WELCOME

appy New Year to one and all! Mine came in with a clatter and a bang; I was putting the rubbish out on a damp, miserable New Year’s morning, completely unaware there had been an overnight frost. I performed some spectacular arse-over-tit acrobatics for any neighbours who happened to be watching before finally ending up in a crumpled heap on the path. It’s good to know that I still bounce and the only real damage that was done was to my pride! In this first issue of 2021, we welcome aboard some new writers. Anthony Carr is an experienced harvester operator from Bellingham in Northumberland and has published his first feature in this issue. In his mid-range harvester roundup, he has interviewed various operators to get honest feedback on the machines they use. He has just started a mid-range forwarder feature, which will be featuring in our April Issue. Matthias Wüthrich lives near Zurich in Switzerland and is passionate about his work in forestry. He will be contributing to the next magazine with interesting forestry features from around central Europe. We are still looking for more people passionate about forestry who have a working knowledge of the industry to join us on a freelance basis. We are looking for help to cover features and exhibitions both in the UK and overseas. We are happy to work around your full-time employment; writing skills are not essential as you will get full support, but you must be able to communicate and write in English. If any of this is of interest to you, please email Rab at: forestmachinemagazine@mail.com We have some original and exciting items planned for you throughout this year; we are starting off this issue with a free centrefold poster, which will feature in each magazine going forward. Don’t forget to check out our free bi-monthly emag which has completely separate content to our printed magazine. If you sign up on our website it will keep you entertained in the months between our printed editions. Take Care and Keep Safe!

This was a great job to trial the new MultiGrab as it gave us plenty of more ideas on what were the most important features of the grab. Firstly, it had to be accurate enough to sort the wood scraps from the ruins. Secondly, it needed to have both “the finger tip” grip and the ability to close with a tight enough grip so you could just take any piece of plank in the grab and trust that it will stay in the grip firmly and not cause any danger to the groundwork’s working close to the machine. Thirdly, it had to be solid, but still agile enough to tear down the chimney safely and accurately. Then, when we were cleaning the foundation, we noticed that the grapple must open a fair bit so it moves out of the way and gives you a good visual on what you are scraping. Finally, when the plinth was removed it also had to be sturdy enough to work as a lever to get the big blocks of the foundation dug up. Later along the way we have already used the MultiGrab for digging up stumps from a felling site, digging up boulders from yards, stone wall building with both natural boulders and with square blocks, loading brush into the forwarder and so on. We have even used it to fold scrap cars in half.

ALWAYS READY

RECOVERING SUNKEN TREASURE BY TERO NURMI

ust like the fire brigade, Arto Vuorijärvi from Kauhava and his shiny red Scania lorry loaded up with his specially built Rottne F12 debogging forwarder, are fuelled up and ready to go anywhere in Finland at the drop of a hat. His new Rottne F12 has recently replaced his old faithful, and still fully operational, 1983 Rottne Blondin which has rescued hundreds of sunken machines over the years and is still fully operational. It all started when Arto Vuorijärvi was in his 20’s. He was living in Kauhava and was employed at the Jorma Lillbacka factory. This was the foundation of Arto’s entrepreneurial hopes and dreams. He started out working as an engineer and his skills were soon recognised as he quickly progressed to become the industrial adviser Page 6

for the Jorma Lillbacka Power-Park, this is an amusement park in Alahärma. “You could only work eight hours a day, being young and enthusiastic I wanted to work much longer, one of my co-workers, who was also operating a forest machine at the time, suggested that I build a recovery winch. This is where it all started. My first winch was tractor-driven, it worked well enough but manoeuvring it around was quite a challenge. Firstly I had to make some money before I could even think about being able to afford to upgrade my equipment and purchase a Rottne Blondin,” IT HAS CARRIED OUT HUNDREDS OF RECOVERIES WITH A 100% SUCCESS RATE

www.forestmachinemagazine.com

February 2021

Above left: My faithful Rottne Blondin, is still fully operational today. The general appearance of the machine is deceiving, although it looks a little odd it is highly efficient and is a forwarder conversion. Above: Tatu Rintamäki and Arto Vuorijärvi have known each other for over a decade, their chance meeting came about when Arto was called upon to de-bog his Timberjack. Left: Rottne has semi-flotation tracks where Vuorijärvi has welded on 50-millimeter grousers for extra traction.

In a winching career spanning over three decades Vuorijärvi has de-bogged more than 800 machines and the tractor unit has only ever broken down once. “The 400 tonne pulling force winch has been 100% reliable and has never let me down, the main cable is 120 meters long but we can extend it so we can winch from a distance of up to 1km. It took quite a lot of thought in the beginning to build an efficient winch which was strong enough but we got it right as we have never run out of pulling power. Band tracks are used to increase the traction power of the base machine”. When the Rottne F12’s first started arriving in the Finnish forests from our neighbours in Sweden we were delighted as we had found the perfect base machine to replace our faithful Blondin. The F12 was a lightweight 8WD forwarder which is ideal for travelling on wet and boggy ground. “This wasn’t a straightforward project and a lot of ideas were banded around before a design was agreed on and work could actually commence. The large wheels and low ground pressure of the Rottne F12 ticked all the correct boxes” said Tatu Rintamäki a forestry machine operator. February 2021

Once we had all agreed on the base Peurala worked on the winch gearing, Vuorijärvi was responsible for the fabrication work and Suomen Työkone Oy designed and implemented the hydraulic system”. Arto wanted this new winch to be fully hydraulic as the previous one had been mechanical. “The main advantage of using a hydraulic winch is that the winding speed of the winch is fully adjustable and offers a smooth and powerful pull when under load. This is much safer as there is no snatch and reduces stress and damage to the equipment. We made the ground anchors so they could be raised and lowered with hydraulic rams, Tatu came up trumps with the design and the end result was much better than I expected. I had much more time to spend on fabricating them than I initially thought. When Covid-19 descended all my holiday plans for the year were cancelled and I spent all summer in my workshop. Everything was built for strength, most forestry and construction equipment is made so that although strong it is not overly heavy, with our winch it was the opposite and we made it as

The extra working lights were a great investment.

strong as possible. Another alteration we had to make was adding extra cooling so we could work in the hottest of summers as well as the cold winters. Our new Rottne has much more power than its predecessor – I can safely say that there is sufficient power for our requirements, the only addition is band tracks for lower ground pressure and increased traction. Theoretically, the winch cable is the weakest link in the equipment, but it’s much stronger than before and nothing gets tangled up. The real challenge is the anchor points of the equipment we are winching,” Vuorijärvi states. “Our biggest challenge is attaching the winch to the bogged equipment, the anchor points are often to weak or in some cases they don’t exist at all. When the machine is severely bogged getting the winch attached can be a daunting challenge on its own. Good preparation is more important than the task itself; first, we need a secure and strong anchor point. When the machine starts to move you need wooden bearers or something similar in Page 8

front of it so it has something to climb up onto. One machine was a nightmare and we pulled it 250m before it climbed up onto the surface”. In mid-August, the machine was still new and shiny as It hadn’t been put to any real tests yet. “So far, I had only de bogged one excavator and moved a large rock,” Vuorijärvi says. “The rock in question was between 150 and 200 tons and I winched it about 100 metres from a field to a garden, this was still well under the maximum pull of our new machine. We were going to do a presentation with the Rottne for the Finnish Forestry Department in the autumn, but due to the current Covid situation, the plans were changed. SAFETY FIRST “Recovering bogged equipment can attract interest from curious members of the public. A successful recovery is collaboration between the machine owner, the operator and me. I assess the situation and pass on my opinions but the final decision is made by the customer who pays the bill”.

THE PAST YEAR HAS BEEN FAIRLY PEACEFUL Vuorijärvi recovers about 25 machines each year, usually one every two weeks, he also will operate equipment for local farmers during harvest time. He also carries out contract work with his own excavator and does engineering work in his workshop. His customers know that his recovery business takes priority over all his other work but since the outbreak of Covid his call outs for recoveries have decreased but luckily he has had plenty to do keeping up with his other work. “Excavators account for about 90% of my recovery work with the remainder being forestry machines and equipment that has fell off the back of a lorry and ended up in places like ditches”. “My advice is that as soon as a machine starts to get bogged stop immediately and ask for help, trying to get out on your own often makes the situation far more serious and can cause a lot more damage. Getting assistance from a nearby machine can often eliminate the need for me and my winch. When the engine submerges and the water starts to rise so does the repair bill “ says Vuorijärvi with a wise wink. February 2021

VERY FEW PEOPLE ARGUE OVER THE COST. The minimum charge for Vuorijärvi’s winching service is five hours with all his travel expenses on top, after the machine has been recovered successfully the customers are delighted and never complain over prices. “Often other machines have been used to try and recover the bogged machine and end up in the same situation. One time a customer called and thought I was too expensive so he used another machine for the recovery. This machine also got stuck so he called in a third machine which got stuck as well; he soon changed his mind over my prices then”. Tatu Rintamäki and Arto Vuorijärvi got to know each other back in June 2009, Tatu was operating his father’s Timberjack when he got bogged. “I had been taught that if I ever got bogged I was to stop immediately and call for help. I phoned my father who in turn called Arto and within an hour he was on site. I questioned whether it was worth getting outside help as it wasn’t severely bogged. My father explained that if you calculated the cost of moving another machines to my site, operator costs and the loss of earnings

www.forestmachinemagazine.com

Page 9

while it was de-bogging me then it would have been more expensive and with no guarantee of success”. Arto Vuorijärvi has travelled beyond Finland with his winch “I have recovered machines from all over Finland and also been to Estonia and Sweden, I have been asked to travel to Russia and East Germany but that was just too far to go. Four Excavators and two winches had been trying for over a week to recover a Finnish contractor’s bogged machine in Estonia. In that time they had only succeeded in moving it one meter, when the Finnish contractor contacted me for the third time begging for me to help him I just couldn’t refuse. Once I arrived it took me just three hours to get the machine out” Vuorijärvi has recommended that contractors who are working on soft ground to purchase extra insurance cover which includes any recovery costs . “As far as I know, they have worked very well, even those who have broken through weak ice. With insurance, you can get the help you need and not have to worry about the costs and they also compensate you for any damage caused to the machine. Page 10

Although when machines are bogged the circumstances may look similar but from my experience no two recoveries are ever the same. Some have more resistance and bring more challenges than others but no matter what we face we always get there in the end”. Text and photos: Tero Nurmi

F Te RGL Bogmaster with an ultra low footprint on a diseased site in Dunoon.

February 2021

ounded over 30 years ago, by Bob Little, RGL Plant (Moffat) Ltd. grew to become the leading specialist mulching contractor in Scotland for soft and challenging sites. The surge in wind energy and upland peat bog restoration works, opened up big opportunities for the forest sector, but there was a catch; you had to be able to first access the work and then be able to actually do the work. The vast majority of sites were situated in remote and highly inhospitable areas and included some of the deepest and wettest peat sites in the UK. A way had to be found to do the work, www.forestmachinemagazine.com

by existing contractors who had won contracts and for the small collection of firms that stepped up to meet these new challenges. The only way forward was to use LGP equipment and as everyone in the forest industry knows, this type of machinery is not available off the shelf and companies had to either turn to specialist engineering companies to convert their machinery, or as in Bob Littleâ&#x20AC;&#x2122;s case, they decided that they would build their own. The only real standard across the mulching industry, was that excavators would form the vast majority of mulching machines Page 13

for this new type of work. Although some tracked purpose-built equipment found its way into the North, it was the excavator mulcher concept that was to swiftly dominate the battlefield, when it came to durability and the ability to access and cover the different terrain and tree types. Tree and vegetation clearance is hardly ever on good ground and this is of course why trees were planted on it in the first place. Almost all tree clearance falls into one of these ground types: Soft, rocky, steep or a combination of all three! Similarly, trees to be cleared are invariably one of a few types: Small and failed/checked crops on deep/wet peat. Larger crops, such as Lodgepole, that had been planted back in the sixties, with almost no hope of ever being recovered as a viable crop, especially once the trees had fallen over or suffered windblow in the soft conditions. Harvesting residues and stumps from cleared commercial crops on land that had been designated for restoration or change of use, such as bird habitat restoration, or simple large-scale clearance for turbine bases, access roads, powerlines and to minimise the effects of wind currents on turbines. The common denominator here is that any mulching machine for this type of work that has to make reasonable progress needs both low ground pressure and horsepower. Lots of horsepower! Many sites also had very tight program deadlines and alongside the usual weather and ecology restrictions, many of these were simply huge, with thousands of hectares of trees to be mulched. This all added up to make a very tough working environment, with engineering and operational challenges that many would not survive and made the people involved into a pretty special breed.

RGLâ&#x20AC;&#x2122;s Hydraulic Thumb used with the bucket to grab stumps, rocks, concrete or other objects to safely remove them.

Page 14

With some exceptions, the majority of contractors opted for converting excavators to larger and wider undercarriage and then running conventional mulching heads, powered by priority valves (known as â&#x20AC;&#x153;stealing oilâ&#x20AC;? from the excavators existing hydraulic system), but RGL decided to do something

www.forestmachinemagazine.com

February 2021

very different. Adding a second engine to an excavator is not a new idea and many examples of this exist around the globe, but what is unique, is the way the RGL went about it. Early machines utilised complete engine transfers â&#x20AC;&#x201C; grafting in bigger engines and hydraulic systems, as well as adding powerpack engines to other, smaller, lighter excavators. Experiments with merging 30 ton excavator track bases, with 13 ton excavator top equipment were tried, all with varying degrees of success. Along this often difficult and testing road, other lessons were learned the hard way, like how much stress something that was primarily designed for digging holes on a building site, would actually put up with, but over time, the basic mulching machine methodology was refined into three basic designs. 1. A heavily modified excavator of less than 20 tons weight, with longer and wider track frames to reduce the ground pressure, with a second â&#x20AC;&#x153;powerpackâ&#x20AC;? engine to power the mulching head. 2. A completely custombuilt machine, based loosely on an excavator and using some primary components/ features, but with enormous power and durability, all built onto a super-LGP chassis, that can accommodate 6 foot wide (1.8m) tracks, whilst still being narrow enough to be moved on roads, without being dismantled. 3. The re-powered excavator base on a machine above 20 tons, where the standard engine is replaced with a much more powerful one, along with all the additional cooling, strengthening and other required features to cope with the stresses caused by this type of work. The final piece of the jigsaw puzzle was the mulching heads themselves. RGL quickly found that standard equipment fell way short of the sheer strength required to drag the machine about, as well as coping with 400hp and above at the rotor, so they set about building theirs from scratch. Without giving away too many technical secrets, the original design heads are all still in use today and have cut literally millions of trees between them, with almost no durability issues and a new design is about to be used, that will hopefully increase production by a further factor above other standard equipment.

The result of all this was to end up with three primary mulching machines on the RGL “fleet” – a name that has loose connotations with shipping - and looking at some of the waterlogged sites that were worked over the years – seems very apt! The current fleet comprises of the 400hp V8 powered “Bogmaster”, a 530hp Doosan DX180-based twin-engine powerpack and a 600hp Kobelco based re-powered twin-engine excavator. The machines go to work on a variety of sites, many of international significance, such as Flanders Moss and many others. Powerline upgrades, including the recent Inveraray to Port Ann upgrade for Scottish Woodlands/SSE and other restoration works, as well as many diseased Larch sites have all been completed. Further improvements to the setup included designing some bog mats that can be easily and quickly repositioned by the excavator on the wettest of sites, as well as building or modifying the usual collection of recovery equipment, tracked mobile workshops, bowser carriers and 4x4 vehicles. What now for RGL? As the demand for specialist mulching rapidly gathers pace again, with powerline upgrades, new wind energy sites and the expansion of existing ones and a whole host of other restoration works, bird habitat creation and diseased Larch clearance, the rush is on again to expand the mulching side of the business again. A big upgrade is under way, with the existing machines being rebuilt and improved still further, along with some more new mulchers, that will be coming on stream as soon as they can be built. The engineering side of RGL is also starting a planned expansion and will soon be offering bespoke engineering solutions to the forestry sector. We caught up with RGL on a diseased Larch site in Dunoon, where they were working for Craig Downie of Specialised Rural Services and RTS Forestry. Craig (a part-time operator for RGL) was operating the Bogmaster on some pretty challenging terrain, with the usual mixture of steep slopes, deep peat and rock and as they say in those parts, “That’s Argyle Page 18

for ye laddie!”. The machine was powering through the standing crop and was on it’s “standard” 1m wide tracks, rather than the 1.8m wide LGP setup, on account of the extremely uneven ground and large rocks that would have swiftly destroyed the wider setup. With plans for a new “super-powerpack” well under way (and two more smaller 400hp powerpacks about to be pushed through the workshop into the mulching fleet), the RGL fleet will number five machines by the middle of 2021 and anyone who knows RGL from the past would be well advised to “watch this space”, as some very trick kit is planned. With forestry becoming more important than ever to the Scottish and UK economy, RGL are looking at a busy future. Get in touch if you have sites to clear or problems to solve. www.rglforestry.co.uk

MID-RANGE HARVESTERS

AN OPERATORS PERSPECTIVE

By Anthony Carr

ver the last 40 years, timber harvesters have changed very little in appearance. Although in terms of productivity, reliability and comfort, they are a million miles away from their predecessors. Today’s harvesters are all very capable machines and all do a great job of harvesting the timber that this country needs. All manufacturers think their equipment is better than their competitors, but in truth some machines are more suited to certain types of conditions than others. This feature isn’t about comparing one make against the other, our intention was for honest and open feedback from operators. Anthony Carr interviewed a random selection of UK operators who have used their harvesters for a considerable length of time and are in a position to offer their opinions.

Anthony Carr My interest in forestry goes back as far as I can remember, with me spending most weekends and school holidays alongside my father Mick Carr who ran his own contracting business. I left school in 1981 at the age of 16 and went to work for my father using a chainsaw. After his death, I moved on to various other contractors including TPH and big Les Charlton until I left the industry in 1988. After six years operating various plant machines I returned to my spiritual home to operate a forwarder for John Lawson. I then went on to operate harvesters for P.B.T before joining Walton Logging in 1999 were I remain to this day as a harvester operator.

and thus improved uptime for the machine.

TIMBERMATIC MAPS

TimberMatic Maps registers the harvester’s route and felled assortments with the exact location of each log. The forwarders working at the same site are seeing an accurate, real time situation and the harvester operator also sees the location of the forwarders. The operators can mark avoidable or difficult areas on the map, or any other notes from the terrain. The communication between the operators will improve as the data is stored in the system and is not dependent on a person’s memory. The data between the machines is updated through a cloud service. TimberMatic Maps is a standard feature in new John Deere forest machines and it is available with an upgrade kit for older models. The application requires 4G MTG and HPC15 (XL4) computer.

everything needed for base machine control and monitoring, measuring and bucking in one configurable user interface. The use of just one system makes the operator’s work faster and easier. Several pressure sensors have been added to TimberMatic, making it possible to adjust most settings from inside the cabin – and even without tools. The pressure sensors make machine adjustments and condition monitoring easier via the machine’s on-board PC: • • •

work and transmission pump pressures delimbing knives feed-roller arms.

Additionally, the new software version enables Remote Display Access (RDA) via Internet (either MTG or other modem). RDA means faster troubleshooting by maintenance people

Robbie left school at 15 and went to college for a year before joining John Deere forestry at Carlisle. After serving a three year engineering apprenticeship in the workshop he then went on a service van for 18 month. After this he began working for the family company, Walton Logging LTD, where he has been ever since. He began with 18 months on the service van before operating various harvesters up to his current 1270 G. “Overall the 1270G is extremely reliable” said Robbie. “It has done 1060 hours and apart from a few small warranty issues I haven’t had to stop because of breakdowns. On my current site I am cutting a 0.34m³ crop which is mostly bent and twisted with a lot of multiple stems. Fuel consumption on this site is 17 litres per hour and production is 21.4m³ per hour. It will climb a house and to date the transmission has never blown off. It is good on soft ground; the head is fast, accurate and reliable, all in all an all round excellent machine”.

BASE MACHINE “The frame brake is really good with no real issues. After operating older machines in the past, the new frame brakes are a lot better. I had a drive on a 1270 test machine last year with a prototype frame brake which uses stabilising rams and it was so much better. These should be installed on future machines. Refuelling is by the quick fit coupling at the back of the machine. The only slight problem is that because of the eight wheels, the back end of the machine is higher. A bit more thought is required when I position the bowser so I can reach the coupling and switch”. On the whole Robbie says the hose layout is good, the only issue is when the machine steering is on full lock the main feed hoses in the centre of the machine push up and rub on the bracket which causes failure through time. When the machine is at an angle he can feel the vibration of the hoses rubbing. “The machine is serviced every 750 and 1500 hours” continues Robbie. “John Deere takes care of the 1500 (big) services and Colin and I do the

750 ones. Servicing on this machine is pretty straight forward, the only problem being is with certain fuel filters needing a special tool to remove them, the worst one being so close to the chassis making it impossible to get a filter strap round it”. Robbie also pointed out that on other manufacturers’ machines, to save dropping the big belly plates, they have smaller access hatches underneath for draining the oil and greasing the propshaft, and he felt this would be a good addition to the 1270G. Robbie says he could do with more storage, one of his main complaints is there’s nowhere to keep his electric grease gun. A good addition in recent times though is that on the opposite side of the cab from the driver’s door is a compartment for the essential spill kit. Overall Robbie thought that the lighting is very good; the only addition would be to add more lights at the back of the machine which would activate when reversing.

CABIN “The cab is really comfortable with everything where it needs to be and with more storage than I actually use. The computer is very easy to use with all the information needed on the work screen and straightforward to see. The vision is brilliant, obviously with the John Deere you have the blind spot with the crane in the middle but other than that it’s excellent. The levelling is really good it is instant and it keeps itself level when driving across the site. The one thing I feel that would improve it is greater levelling forward

Rotating and levelling or fixed cab

and back. Although the lighting is perfectly adequate more lights on the front would be a welcome addition”. The cab greasing is taken care of by two banks of nipples under the cab. These are optional extras with Robbie saying these are well worth the upgrade. This system does away with getting unwanted grease on your head and shoulders when reaching under the cab to grease the standard set up.

CRANE For the size of the Machine Robbie says the crane power is very good. “Reach is adequate but I could always do with more. The game changer on this machine is the IBC as it is fast, smooth, precise and powerful” said Robbie. The hose layout is neat and tidy on the crane with the hoses under the kingpost causing the only notable problem. These hoses are kept

out of the way to improve vision, but as Robbie pointed out the downside of this layout are the hoses rubbing together under the kingpost leading to hose failures, which are awkward to replace. The crane lights are on the underside of the main boom which Robbie feels are adequate but additional lights on the underside of the dipper boom would be a welcome addition.

415 HEAD For performance Robbie feels that this supercut saw is now the best on the market. The downside coming from slightly excessive bar wear. He also says the tensioning could be improved as the chain occasionally runs off the rails. Chain wear is excellent though with chain breaking being an exceptionally rare event. “Felling is generally good” said Robbie. “Sometimes it is difficult to get the head square on the tree when felling large trees with big toes. When felling with the head at an angle the head loses grip resulting in the saw getting stuck”. When double cutting to make sure he cuts right through the stem he has to make sure to get the head further round the back of the tree due to the positioning of the saw box. This head is running after market V-TEC feed rollers which Robbie prefers to the standard ones. The single speed motors give really good torque and grip with excellent delimbing. As with most heads, feeding on large stems is a problem with grip. The machine has slow feeding and feed limitation options but Robbie says a proportional feed would be a good addition.

Robbie uses sequence control to start the tree then uses manual saw for crosscutting. Measuring is really good with calibration via callipers keeping everything accurate. “The hose layout is shocking with lots of hoses sticking out which are prone to getting caught” continues Robbie. “They are a nightmare to change although it has been improved by putting a join in one of the feed roller hoses. This means it isn’t necessary to take the head cover off to change it. Some of the hoses under the head cover are awkward to change, with having to take other hoses off to get to the burst ones”. Another thing Robbie commented on was hose quality maybe isn’t as good on new machines compared to the replacement hoses he uses. The head is relatively easy to grease. The two issues with greasing is the access to the two nipples on the top knives which are really awkward to get to - a hole drilled through the chassis would be an easy solution to this problem. Another problem is the nipple behind the measuring wheel which is sometimes difficult to get at due to sticks getting jammed behind the measuring wheel electric hose”.

struggle especially with the bigger trees in the wind-blow, he is still managing. “Where the machine really comes into its own is in smaller crops. 0.4 m³ and 0.5m³ being the optimum size. The machine is excellent in crooked stems. The Scorpion performs well on soft ground although I feel the back end of the machine does seems to go down easier than the front”. Graham is currently harvesting on a local site cutting direct for the forestry commission. It is a second crop site with a 0.9m³ tree average across the whole site which includes patches of wind blow. The average tree size Graham has harvested so far is 0.78 m³. He is achieving an average production of 28.4 m³ per hour and using 18.5 litres of fuel per hour.

BASE MACHINE

enables comprehensive services now and in the future. The easy-to-use tool offers assistance in harvesting equipment maintenance and work planning, along with providing access to extensive reporting.

Operator: Graham Robson, 35 TPH LTD.

Graham Robson has worked for TPH off and on for 16 years. Graham started on a part time basis operating a forwarder on nights and weekends. He began working full time 9 ½ years ago on a forwarder for two years before progressing to a harvester. After operating various John Deere harvesters Graham changed to the Scorpion King 18 months ago. Graham is very happy with this machine; he finds it very operator friendly with visibility and stability being exceptional. Although

“The frame lock uses a ram either side of the chassis in the centre section which are linked to the cab levelling rams, this system gives unparalleled stability. One feature I really like is the alarm system which warns if the machine is in danger of tipping when reaching out too far on steep side slopes. The refuelling point is at the rear of the machine and the hydraulic oil filling is under the front hood of the rear section. The hose layout is one area where the machine could be improved, especially the hoses under the cab and the centre section. This machine is on a service contract with Ponsse, with services at 750 hour intervals. Graham helps the engineer out during these services and he finds the machine very easy to work on with filters etc being easily accessible. “Storage is adequate but I could always do with more. The side pod on the rear is handy though for storing hoses, and there

is another compartment in the front step. There are 2 led lights under the hoods

for servicing with a further one for refuelling”.

CABIN “Although the cab is small, the all round comfort is excellent. One of the main reasons for this is the stability of the machine as I am not getting rocked about all day and at the end of my shift I still feel really fresh. The seat is heated, has a cold air blower and is easily adjusted. The armrests are comfortable and I really like the comfort grip levers (pillars). The noise level in the cab is quiet, the only downside being caused by movement of the hydraulic pipes and hoses while being worked. The vision on this machine is unparalleled. With the cab rotating 320 degrees you are mostly looking out of the front window even while reversing. Even if I have to look out of the side

and rear, vision is good because of the narrow pillars on the cab. When the machine was new the cab had to be calibrated a couple of times but since then it hasn’t needed to be touched at all. The levelling works really well, the only glitch being when pulling big trees from the side it will pull the cab down a little bit but other than that, perfect. Lighting is covered by a bank of lights on the front of the cab below the window and a bank on the top of the cab with further lights on the side and back. Despite the fact that this is an easy computer to use I must admit it took a bit of getting used to after operating the John Deere system for years. I do feel however that there are a lot of similarities between the two systems”.

CRANE “I find the crane to be really smooth, with the slew power on the machine being really impressive but I feel the main lift could be better. I have to work close to the crop to achieve the best results. The one function I do really like is the automatic extension which works automatically

in conjunction with the dipper arm, using the left lever. The hose layout on the crane is excellent with hoses down to the head easy to change and there are two lights under the dipper boom and six on top of the king post providing excellent lighting”.

H7 HEAD “This saw is phenomenal. The machine is coming up 18 months old and I haven’t had any problems at all. Where the saw bar fits on is really

strong which does away with much of the sideways movement. Bar and chain wear is excellent. The head is good for felling but I am currently in a 0.8 metre average job so sometimes the head is letting go during felling on

the bigger stems.

as it very rarely alters”.

The feeding on the head is fantastic. In large trees it has a proportional feed, operated by a toggle on the pillar, which slows things down to get an accurate start on the tree. The head handles bent twisted stems with ease due to the reaction bar, and being able to feed the tree right out to the tip and then right back to the start without losing grip is a major plus point. De-limbing is really good and capable even on edge trees”.

“The hose layout on the head is exceptional. None of the hoses are exposed I have had problems with catching feed roller hoses on previous machines I have operated. The feed roller hoses are really well routed on the H7 head, and I’ve never caught one yet. All the grease points can be reached with the head in one position although the two nipples on the tilt frame swing arm are difficult to grease and could do with being extended so they aren’t as difficult to reach.

Graham uses the semi automatic system for sawing. This system is utilised by keeping the saw button pressed just before it reaches its length and the saw cuts soon as the length is reached. “Measuring on the machine is very accurate; it’s the best measuring head I have ever used. I calibrate the measuring on average once a fortnight but I do feel that it isn’t really necessary

Overall the head is very reliable and there has been very few issues with it. One problem though is the measuring wheel bearing wear. I have been changing these at nine month intervals, before they actually fail. Another issue is with hoses on the tilt frame manifold wearing through including the hose housing the electric cable”.

FINAL POINTS CHAIN OIL USAGE

The oil flow for the saw can be adjusted via the computer. Graham says he usually uses about four litres of chain oil a day, which is ample as he has no issues with excessive bar wear or broken chains.

LOW LOADER

If there has to be a bad point of this machine, transportation is it. The machine itself is easy to put onto the low loader but knuckling up the crane to get it low enough in Grahams words is a real headache. Fitting of quite a few guards is

needed and then some special manoeuvring techniques are required to get in to place.

RELIABILITY

Very few problems, covered elsewhere.

BACK UP

“Back up is A1, on the rare occasions I have had to call out a van, they have always been there the same day, even at 3.30 on a Friday”. If Graham needs spares he orders them over the phone and they are usually delivered to his house the next day.

“The frame brake on the 931 utilises a ram on either side of the chassis, when coupled with the 8 wheels it provides faultless stability even on steep slopes. Refuelling is accessed via a removable step which clicks into place to allow access to the fuel and Hydraulic filling points.

Operator: Keith Palmer, 53

The autolube takes care of most of the base lubrication with four greasing points on the main slew bearing and two on the driver’s access step being the only ones needing to be greased manually”.

Blacklock Harvesting.

Keith spent his early years driving Lorries around the Scottish Borders area before

One issue I have though is that when checking the Hydraulic oil level, I have to remove the bonnet protection bars before lifting both bonnets to see the sight glass - a hole cut in the side of the bonnet would be an easy solution.

The hose layout on the base machine is generally good, the only problem being in the centre joint where the hoses go under the cab which has resulted in a water hose failure. Storage is good

with room for the toolbox etc in the front step although extra storage can be obtained by taking the plastic urea tank out which leaves room for hoses.

CABIN After year’s operating Komatsu 941’s, Keith went onto operate a different make of harvester for about two years. He found the computer a little bit difficult to use at first but became used to it over time. Now back on a Komatsu it has taken time getting used to the 931 XC computer. He is now however, comfortable with it and say it is very user friendly. “Cabin comfort is excellent with the overall stability of the machine keeping things steady, along with a roomy cab and excellent seat. The levers are the wooden Komatsu ones but I find these better to use than the mini levers I have used in the past, I find them really comfortable with the buttons just where they need to be. Storage inside the cab could be a lot better, if I put anything in the nets in the door they fall out when I shut the door. The two pockets behind the seat provide some storage but things rattle

around in them so much that they are very annoying. Vision is excellent which really maximises performance, the only slight problem being if a tree gets caught in the crop on my right-hand side there is a blind spot due to the main boom. However I can feel when the tree is caught so this doesn’t cause me any major problems. Levelling is excellent on steep ground and it levels further than machines I have operated in the past”. The cab has courtesy lighting which gives a red glow around the cab while operating in the dark with the lights becoming white when the door is opened. Cabin greasing is part of the autolube system which would probably last for two weeks, but is filled up weekly to keep things running smoothly.

CRANE Although the main lift is perfectly fine, working close to the crop gives the best results. One thing Keith did remark on was, when handling large trees or a full diesel bowser or site safe, he has to be careful that the head doesn’t come in and hit the front of the machine due to lack of power in the dipper ram. “Slew power is good as is the extension” said Keith. “The machine stays stable

even at full reach out to the sides”. To keep the crane working at an optimum Keith calibrates the levers and all the functions on the crane at least once a fortnight, this is all done within the computer which is relatively straightforward to do. “The Hose layout on the crane is generally good. The one hose I have had problems with is the one that houses the electric cable down to the head.

BOOM: 230H

Gross lifting torque 229 kNm Reach 8.7, 10 or 11 m

This problem occurs while working on steep ground as it causes an acute bend on the hose where it goes into the electric box.

With 4 lights underneath the main boom and 4 on the side of the crane it provides excellent lighting”.

C144 HEAD “Felling with this head is good as the well designed saw box enables me to cut the stumps low. I fell the trees manually in larger crops and use fully automatic when I am in smaller stands. One short press of the saw button is all that is needed to cut all the way through in the fell cut; this can be overridden by simply pressing the button again. Feeding is excellent it has a good grip on big trees and accurate measuring is achieved when care is taken with big butt logs. On the rougher trees I am able to feed the tree all the way to the tip and then back to the butt with no loss of grip. The head is able to de limb rough trees but I tend to leave them for the cutter so as not to put too much strain on the head”. Keith uses the semi-automatic method of crosscutting, holding his finger on the saw button before the tree reaches its length which results in instant cross-cutting. “The measuring is good on this machine. There

have been problems in the past with Komatsu machines but I feel that they have it right now. Calibration is done via callipers every 1000 m³ which are very easy to use. “Very Quick when the bar and chain are 100 %” were the words Keith used when describing the saw, and he added even when the chain goes dull it still cuts reasonably well but he doesn’t recommended this as it causes excess wear on the bar and chain. Chain snapping is minimal with the only slight problem being the chain sometimes catches the side of the saw box. This Head has done 3500 hours. The only hoses that I have had to change were two knife hoses which had not been crimped properly when new. The feed roller hose layout is perfect unlike other heads I have used in the past. Greasing on the head is well thought out with the inner greasing points all accessed via a bank on the outside of the head with the other ones easy to locate”.

FINAL POINTS CHAIN OIL USAGE

LOW LOADER

“The machine is easy to put on the low loader. Folding the lights on the cab forward, and

moving the lights under the main boom to the side, give the only minor gripes to folding the machine up for transport”.

RELIABILITY

“Overall the C144 is a good reliable head;

9 the Achilles heel has been the inner feed rollers. The rollers are in line rather than side by side with the top one being powered via a sprocket between the two rollers. If the top roller becomes jammed and the bottom roller keeps on turning it results in either blowing the motor seals or breaking the bolts on the sprocket. The last time this happened new stronger bolts were used and so far they seem to be okay. Apart from this a failure with a top knife has been the only other notable issue”.

BACK UP

“Good and getting better. A lot of the original engineers have left over the years and the younger lads that have replaced them are doing a good job”. One aspect Keith is really impressed with is the Team Viewer system, this allows for an engineer from Komatsu’s base in Longtown to be able to alter his machines computer no matter where it is. This system can be accessed even without phone signal, with the engineer being able to change settings as though he was actually sitting in the machine. “I was recently working in Ireland and had a problem with the knives not working properly, by turning the cab and crane round and dangling the head out the back of the machine, the engineer was able to watch what the head was doing via the reversing camera and diagnosed the problem”.

his 21,000 kg harvester is available in six or eight wheel drive and uses a six cylinder AGCO Stage V 258 hp engine and the hydraulic system offering 285 l/min at 1500rpm.

The 6H stands between 2640 and 2930 mm depending on tyres. It has ?? mm ground clearance, a steering angle of +/- ??° and weighs approximately 21,000 depending on harvesting head. This model is supplied with a Mesera 221H crane and has three reach options; 8.3, 10 and 11m and can be fitted with a choice of three Logset harvesting heads - TH45, TH55 and TH65. Logset have developed a base machine control system, the TOC 2. This control system has been designed so that it is user friendly and straightforward to navigate. Recently updated, the settings for the TOC 2 control system are divided into two parts: basic settings and advanced settings. Anyone can simply change the basic settings of the program, for example, drivers can save their own crane settings in the program. Access to the advanced settings on the harvester can be restricted to qualified technicians. Logset has developed a new measuring instrument system for their harvesters: Total Operation and Measuring Device 2 (TOC-MD 2),

“Comfort in the cab is excellent and larger than I expected”. In 1991 Colin teamed up with Nigel Greenacre, who had also worked for the forestry commission, and formed the company GNF Forestry. Together they worked cleaning up windblow following the 1987 storm. This is the company they are still running today with Colin operating the harvester and Nigel operating one of their two forwarders. Colin and his son C J were double shifting the 6 H on a flat site in Suffolk, with Colin describing the crop as “mediocre”. They are producing an average of 26 m³ per hour with a tree size of 0.3m³ and fuel usage of 18 litres per hour. “Overall reliability of the machine, over the 10,200 hours, has been excellent” said Colin. “The only problem that hasn’t been run of the mill was a broken wire under the cab. RJ Fukes fixed the problem in two hours by replacing the wiring harness”.

TOC-MD 2 which is a Linux-based system. The TOC-MD 2 is able to connect to the TOC 2 control system directly which eliminates the need for a separate PC. TOC2 and TOC-MD 2 control systems are the result of 10 years of development, the TOC control system has been used in Logset forest machines since 2007. The TOC-MD was introduced in Logset machines in 2010. TOC-MD 2 navigation has been recently updated with the latest navigational software.

“GNF Forestry has been loyal to the Logset brand since 1997. Starting with excavator based harvesters before going onto purpose built machines. The machines have gradually improved over the years with each model being better than the previous one. The 6H has been very productive and reliable. The majority of our work is carried out in Norfolk, Suffolk area where the sites are relatively flat with good ground conditions. With the 6H never running tracks and it being fully ballasted to aid stability, it is reasonable on soft ground with extra care being needed to get the most out of the TRS tyres”.

BASE MACHINE to get to. There is a compartment on the main slew bearing and two other side of the machine which houses the batteries. The various greasing points are easily accessed and the hose layout on the Logset is excellent with no failures in the centre joint during the 10,000 hours the machine has worked. The LED lighting on the base is also excellent. Servicing on the machine is done by the operator on the interim 500 hours service, whereas the

main 1000 hours service is carried out by RJ Fukes. The servicing is straight forward; the only thing which was a little awkward to change was the transmission filter” said Colin. A common theme among those I have interviewed is lack of storage. Colin commented he could always do with more. There is storage under the front of the cab for chains, with 2 drop down hatches at the rear of the machine for bars etc. There is also storage in the refuelling compartment for the toolbox.

CABIN “The computer on the 6H is very user friendly. The right joystick of the machine is all that is needed to navigate the computer.

downside with the crane is that it is in front of the cab. I have operated Logset’s for years so it doesn’t bother me that much.

Comfort in the cab is excellent and larger than I expected, there is ample room. There are side pockets on either side of the seat with further storage in the door pocket and room behind the seat for the spill kit. With the cab following the crane I find the vision excellent. The only

Levelling on the cab is very good but it is rarely stretched due to the majority of our jobs being relatively flat. The lights on the outside of the cab are all LED’s giving a good spread for working, and inside the cab there are 4 lights including 2 reading lights. Greasing points for the cab are all easily accessible”.

CRANE “The Crane could do with a little more power on bigger trees. But, as the majority or our work is predominately thinning and smaller clear fells,

The 500 litre fuel tank means less downtime for fuel filling

the crane is more than adequate for our needs. The ten metre reach comes into its own in the thinning’s. The hose layout on the crane overall is very good but if I could make one change it would be a guard either side of the main boom to stop branches getting under the metal pipes. This isn’t

BOOM: Mesera L221V

This isn’t an issue in clear fell but as we do a lot of first thinning’s this can be a problem. Lubrication is via one easy to access greasing

point which services the whole of the crane and the crane lighting is via 2 LED lights either side of the link above the kingpost”.

TH65 HEAD “With the saw running an uprated saw motor and a 14 tooth sprocket it gives excellent performance, good bar wear and minimal chain failures. The head is great for felling and the sturdy well positioned saw box keeps the stumps low. The TH65 gives excellent results even in rougher stems and the feeding is very good. Due to being the owner of the machine as well as the operator I tend to leave the rougher trees to the hand cutter to save on breakages”. Colin also uses the manual crosscutting option as it is what he’s used to.

“Measuring of length and diameter is accurate. I do the Calibration manually to keep things in check when needed. The hose layout on the current TH65 head is an improvement over the previous model, the main improvement being the feed roller hoses which have been rerouted forward then up, rather than straight up. The only failures we have had was due to catching the hoses in tight first thinning’s, none have occurred on clear fell sites. The head is easily maintained with all greasing points being readily accessible”.

ECO LOG 560D

Operator: Neil Fraser

he Eco Log 560 is a six wheel drive pendulum arm suspension harvester weighing 19,100kg with its Volvo Penta 6 cylinder Stage V Tier 4F 252hp engine.

This is a self levelling harvester with adjustable ground clearance from four inches to almost four feet. The independent pendulum arms are able to raise and lower each axle individually. The side mounted crane has reach options from 9m to 11.5m and can be fitted with your choice of four Log Max harvesting heads - 3,000, 4,000, 5,000, 6,000. Eco Log use the DASA Forester operating system. Forester is the latest generation of systems for optimised logging and is the 6th generation system from Dasa which draws on the company’s experiences from previous systems. Development was undertaken in close cooperation with leading manufacturers of harvesters, forwarders and logging units. The result is a product that takes bucking and mechanised logging to an entirely new level.

“The levelling of the base machine is taken care of by the pendulum arms”. forwarders before progressing to harvesters. Last year Neil decided to go it alone starting up his own company Fraser Timber Harvesting Ltd working for Norbord in the Inverness area. The site Neil is currently harvesting is mixed with some spruce, rough twisted pine and quite a lot of windblow and dead trees. Neil is achieving roughly 15 m³ per hour in a 0.25m³ size crop with the machine using 11 litres of fuel per hour. “One of the major assets to this machine is the way it can keep itself level due to the pendulum arms” said Neil. “This system is used while traversing the site and its second nature using the joystick control to keep things level. Another advantage with this system is its ability to sit level going across steep side slopes, where with the powerful crane I can fell the trees and then place them in more accessible areas where I can process them, allowing easier access for the forwarder”.

system for forwarders, Navi navigation system for harvesters and forwarders, Monitor operation monitoring system for forwarders and harvesters and a Care telematics system for communication and monitoring machinery.

Although the machine hasn’t come across any very steep climbs so far, Neil feels the hydraulic drive motors will be up to the task if needed. “With this machine running an upgraded crane and hydraulic system that is usually found on the 580 D, it really is on top of the job. With the smaller Logmax 5000 D head along with the 11 metre reach crane it is a perfect combination for the type of work I do”.

Operator: Neil Fraser, 44

Fraser Timber Harvesting Ltd. After leaving school in 1993 Neil attended the Scottish school of forestry on a basic forestry course. While doing this course he also took part time chainsaw work to make ends meet. After a year at the college Neil then went to Finland for three months attending two different colleges where he gained further experience in operating and maintaining forest machines. On returning home he started working for various contractors, including G&A Watt and Douglas Timber Harvesting, on

BASE MACHINE “With the centre joint of the machine only allowing steering movement, the levelling of the base machine is taken care of by pendulum arms rather than the 2 way centre joint and frame lock systems used on most other machines. Levelling of the machine is controlled by a separate 4 way manual Joystick which once I got used to it, I really like.

Fuelling up is done at the very front of the machine with an easy to get to hose attachment. Autolube takes care of the base, crane and the pendulum arms. I have no problems with the hose layout”. Neil was very happy with the storage on the 560. He was one of the few operators who didn’t comment on needing extra storage. “In the front

of the machine there is a slide out tray above the diesel tank which is good for larger tools with additional storage at the front for a toolbox, fuel filling hose, bars and chains etc. Also stored in here is a concentrated 10 litre urea tank, which before being used is diluted with water from a tank in the crane pillar”. Neil stated that the mixture of xenon and LED lights work really well.

CABIN “The cab is comfortable, everything is easy to access the only issue I have had was vibrations coming up through the floor which is all but eradicated as I fitted extra sound proofing. Because the crane is alongside the cab vision is excellent, even looking past the crane on the right hand side causes no problems due to the large side windows. With the machine chassis levelling with the pendulum arms there is no levelling on the cab itself. For storage there is a compartment above

my head and also a pocket on the left hand side of the cab. Control of the machine is taken care of by the Dasa 6 forester computer which is situated on the driver’s door at the front of the cab. The computer is simple but efficient. It has a touchscreen to alter any settings and is very user friendly and easy to use. Lighting is taken care of by a lightbar above the front window with additional lights on the side and back of the cab”.

CRANE “Strong and Sturdy” were the words Neil used to describe the crane. This Machine is fitted with an upgraded 260 crane that is usually found on the 580 D. “It gives it more power, and with 11 metres of reach, coupled with the Logmax 5000 D head it is more than capable for the work I do. The hose layout on the crane is generally good,

Ground clearance can be adjusted from 4” up to 4’

the only issue is the badly protected crane cables down to the head. I have caught these a couple of times but this is probably due to working in rough UK conditions. This problem has been addressed in later machines and the cables are now being housed in a hose. The crane has two lights on the extension hose bracket and one on either side of the crane Pillar”.

LOGMAX 5000 D “The saw is fast and reliable with no significant bar wear. Because I harvest a lot of windblow I do get chains breaking but this is normally down to the saw getting stuck. Felling with this head is good. One thing to mention is the rubber mounted plate that is connected to the side/bottom of the saw box. This plate acts as a shock absorber taking out the stress to the head when feeding down to the ground to locate the fell cut position. Its fast and powerful at feeding. I recently finished a really rough Lodgepole pine job and the 2 wheel drive head coped really well with the bent and twisted crop. Although the head is capable of much rougher trees I tend to leave them for the cutter to save stress on the head”. Neil uses the semi-automatic method of crosscutting and a manual override when needed. “As a requirement of the main contractor I calibrate the head every day. The calibration is done with the quick and easy use of the callipers which keeps everything in check and leads to very accurate measuring. I feel the hose layout on the head is nice and compact with nothing causing any problems in

the 1200 hours I have worked so far with the machine. The head is straightforward to grease, the only issue being sticks getting jammed behind the top knife guard’s which hinder access to the greasing points. When I first got the 560 D I used the Greasing system for lubrication rather than chain oil. The reservoir for the fluid grease system is located on the side of the boom extension bracket. It needed filling twice a day so I switched to the chain oil system which only uses 3 litres of oil a day. I am pleased with the guarding of the head especially the hydraulic rams which are well protected from debris and tree sap, extending the lifetime of the seals. The hydraulic hose of the rams are also protected by effective guards. I have had the machine for over a year now but due to being stopped because of Covid-19 I have only done 1200 hours. In this time the overall reliability has been very good. I have replaced two knives which had already been repaired, and replaced a top knife spring these being the only real issues I have had. I have also had a few leaking rams which is to be expected on a machine of this age. The rams are easily taken off and resealed which I do myself.

“The Eco Log was sourced from Eco Log in Sweden by Scott Burton of SB Forestry. It was covered by a parts warranty for the first Month after I bought it. This came in handy when a solenoid developed a fault on the injection system of the Mercedes engine. It was replaced with a second-hand solenoid. The only other major problem was that one of the pendulum arms failed due to fatigue and had to be replaced with a stronger version on the front of the machine. The one on the other side is due to be replaced in the near future in case it also fails. Apart from the usual run of the mill, burst hoses etc the machine has been very reliable overall considering the hours it has done”.

I tend to repair most things myself and Scott is always on the end of the phone to offer advice, send parts and a service van will be dispatched if I need it. Back up for the head is provided by Treetop forestry. The Treetop service vans often pass near to where I am based in Inverness so I can arrange to meet up with them to collect any parts I have ordered. I carry out all but the most difficult repairs myself and the servicing at 500 and 1000 hour intervals. Servicing is relatively easy with the removal of side panels allowing easy access to the filters etc”.

“The Ergo handles everything from first thinnings to large clear fells making it the best on the market for our needs”. After leaving school at 16 he went on to a YTS scheme with Fountain forestry learning about all aspects of forestry. After this he started hand felling before progressing on to the winch tractor at 17, where he stayed for another three years. At 20 he spent two year on a forwarder for Grosvenor forestry before moving on to Kleen Kutt forestry where he stayed for 16 years. He moved to his current employer Cox Forestry after this and has been on Ponsse Ergo Harvesters for the last 4 years. Nick Cox started Cox Forestry in 1993 working for Euroforest, with 95 % of their work still coming from Euroforest. First up was a County tractor with a Botex roof mount crane, trailer and a gang of hand cutters. He then progressed to a JCB 814 with a Ponsse head. Nick has stuck with the Ponsse brand ever since which has included ownership of 8 Ergo’s, the most recent one arriving the week before Christmas. “The Ergo handles everything from first thinning’s to large clear fells making it the best on the market for our needs”.

Operator: Simon Hern, 42

Simon is currently on a difficult site consisting of a poor larch crop. The majority of the trees are being felled down to him off a bank-side by a cutter. The average tree size is 0.4m³ and he is averaging 13m³ per hour and using 15.8 litres of fuel per hour.

BASE MACHINE

Cox Forestry.

Simon’s introduction to forestry started at an early age. He spent as much time as he could going to work with his father who was a contractor for Fountain forestry. An early indication to his future career was his enthusiasm to, “have a go” any time his father would have time to let him take the controls of the Massey Ferguson 390 tractor.

Stability on the Ergo is taken care of with a ram on either side of the chassis, which Simon said works really well. “Refuelling on the machine is easily accessed behind the cab access step, with both the fuel connection and Ad blue tank being located at this point. Hose layout in the centre joint was one of the main bugbears of

the recently departed Ergo with around 10 hoses failing in the 3 years of having the machine. The only good point of this problem is that with the box above the hoses being on a pivot, and with help from the forwarder it is easily moved out of the way to allow good access to the hoses. Storage is adequate. The storage area next to the

exhaust has been cut by 50 % due to a new emissions system. However as the machine doesn’t come with a urea system there is ample storage where the tank would normally be in front of the crane. This compartment isn’t waterproof and is prone to debris getting in. Care has to be taken placing the chain oil, bars, chains and hoses in it to make sure they stay clean”.

CABIN “As the seat in the Ergo cab turns around the cab is very roomy with space for a passenger if needed. The seat itself gives sideways levelling which is operated manually. The downside of this is the seat actually touches the side of the cab on steeper side slopes. One of the highlights of this latest machine is the addition of a night heater which is a first for me. I look forward to a nice warm cab and clear windows in the mornings. Vision is excellent with the long windows and narrow pillars. The only downside I have with vision is, as the crane is towards the front of the machine, it is a little

difficult to judge in first thinning’s, but second thinning’s and clear fells aren’t a problem. The computer on the ergo is straightforward to use with settings changes being done by touch-screen and a keyboard. With storage under the operator’s seat and also under the passenger’s seat it is more than adequate. The usual all round LED’s are excellent. The only thing I feel would be a good addition to the Ergo is central locking with the function also operating selected lights that would illuminate my path up to the machine on dark mornings/ nights”.

CRANE The crane on the Ergo is the C5 telescopic version which is best suited to the work Cox Forestry does. “Small first thinning’s jobs right up to large clear fell jobs where 4 m³ trees aren’t uncommon. The telescopic crane is the making of this machine. I wouldn’t be so keen to use the parallel crane option. The two motors provide excellent slew power and along with a strong main lift and good reach makes for a very good crane. The only downside is that there is a little more maintenance to do than on normal

cranes. This is due to the extension chains needing regular adjustment to keep things running smoothly. Another plus point on this crane is its ability to easily fold away lower than the cab, which makes moving on the road, from site to site, a much easier task. The hose layout on the crane is excellent too, including the internal hoses down the boom. Greasing for the slew ring is done via four points at the crane base. The rest of the crane is greased at various points which are easily accessible.

Once a fortnight I grease the rollers for the telescopic boom which is also relatively straight

forward. Lighting under the main boom is good”.

H7/H8 HEAD As this new machine was fitted with the H8 head, and Simon had only one day operating the new harvester before being interviewed, the questions he answered were mainly about the H7 head. “The saw motor set up has been difficult to get the correct combination of chain speed and feed force of the bar, which has caused some chain snap. The improved saw on the H8 will rectify this. Felling with the head is good with Simon telling me of a setting which is new to him which only opens the head up in relation to the average tree size of the last 100 trees. As the head is never fully open it is a lot easier to manoeuvre between the trees in first thinning’s. As Simon had only operated the machine for a day, he couldn’t say if the feed was much better. But he did add how impressive the H7 was in the rougher trees and how well it has served him in the past. “One of the changes on the new head are the plated spike feed rollers which have a cleaning system to stop debris building up. I am not sure about this set up as when the head hits a bend in the tree, the feed rollers seem to do a lot of damage to the stem while spinning. I am not convinced they are any better than the original rollers on the H7. Simon uses a combination of automatic and

manual saw for crosscutting with logs and stakes on fully automatic and manual saw for other sizes. Concentration has to be kept up while using the automatic saw with Simon able to override the system to avoid cutting substandard products. “With a choice of single or double measuring wheel, we opt for the single version which gives excellent measuring. Lengths and diameters are checked daily with calibration being done manually as and when needed but it is a doddle to do. With the Knives floating and the head tilted up all the greasing points are accessible without having to move the head. The only downside being that the grease is quite hard to pump into the nipples on the H7 even with a Milwaukee grease gun. With the new H8 head I am hoping this problem to be a thing of the past. Simons only niggle with the H7 head was the hose manifold on the tilt frame where he says the mounting pin wears then breaks causing hose failure, hopefully this should have been rectified on the H8 with a bigger stronger pin. Other than the above issue, reliability was described as overall very good, with feed roller hoses needing replacing about every four months and the measuring wheel bearing every 12 months being the only other things Simon commented on.

“Folding down the light bar on the cab and supporting the head with chains is all that needs done to prepare the machine for transportation, after this it’s just a case of driving the machine on”.

RELIABILITY

“Apart from the hoses in the centre joint, covered elsewhere, the only other problem has been the header tank on the cooling system. The tank has been replaced three times because of leaks, which Ponsse have rectified. The new harvester has a re vamped system which I have been assured will cure the problem. Other than the

above problems and the usual run of the mill issues we have been more than pleased with the overall reliability of the Ergo”.

BACK UP

“The machine is on a service contract with Ponsse UK. Cox forestry take care of the fairly straight forward 750 hour service, but the main 1500 hour services are done by Ponsse. Ponsse service engineer Chris Davies, who is based in Wales, takes care of 99% of the work at Cox Forestry, even though Chris has about a four hour drive from home, he is usually on site by 7 in the morning. Cox forestry have used Ponsse for years and their back up is excellent. They use DPD next day delivery who are very good. The parts are sent direct to the operator’s respective homes when needed”.

Would have another: “Yes”.

Hold it There!

The tried-and-tested system of the FH constant pulling force winch is now also available as a traction assistance winch attachment. The attachment unit is suitable for mounting on excavators, harvesters, forwarders, skidders and more. Since all the components, including the hydraulics and the FH traction assistance control unit, are mounted in a single add-on unit, little modification of the host machine is required. The minimal modification undertaken to the host vehicle means the add-on unit can easily be used for various machines. For instance, if added to a 25 Te excavator, the TWFH120 can support another machine on a slope(s) using the variable control traction feature as determined by terrain and conditions. Moving the controls from one machine to another is a matter of taking the control unit to the next machine requiring stability. The host excavator can still be universally used without needing to modify or remove the winch which makes for cost effective solutions to many harvesting and processing requirements.

STIHL MS 881, THE WORLD’S MOST POWERFUL CHAINSAW

he new MS 881 is a direct replacement of the MS880 and has a displacement of 121.6cc and 6.4 KW of engine power. This chainsaw has been eagerly anticipated and is built for forest professionals capable of high performance work. It is available with 30, 36 and 41” bar options and uses a .404” rapid super chain. It weighs 9.9kg and has many features as standard:

compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.

ANTI-VIBRATION SYSTEM Intense vibration at the handles of power tools can lead to longterm effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine’s engine are dampened which significantly reduces vibrations at the handles. SINGLE-LEVER MASTER CONTROL All important functions such as start, choke, throttle and stop are operated via a single lever. COMPENSATOR This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs. EMATIC CHAIN LUBRICATION SYSTEM The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, February 2021

it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50. CARBURETTOR HEATING (V) By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures. No other chainsaw offers the same 121.6 cc displacement and 6.4 kW engine power, giving it unrivalled performance. The 2-MIX petrol engine complies with EU5 emission regulations ensuring it’s safe for both the user and the environment. The advanced HD2 filter filters out even finer dust particles ensuring a long service-life. Featuring a one touch stop function for simplified starting. A rounded handlebar makes it comfortable to hold and a hand guard protects the users hand from debris. FEATURING A TOP QUALITY ROLLOMATIC ES BAR The MS 881 boasts the highest quality Rollomatic ES bar for high performance demanded by forestry professionals. The bar nose is fully replaceable for low cost maintenance and upkeep, and angled holes allow for optimum lubrication resulting in a cleaner cut. Sealed bearings in the sprocket nose ensure longer durability and less maintenance saving time and money. www.stihl.co.uk February 2021

The MaxiFleet engine heater function has been made both easier and better thanks to new, connected technology that makes it possible to interact directly with the forest machine’s computer. The new technology brings great opportunities for improvement and this is only step one. The MaxiFleet engine heater function has received several practical upgrades that makes it both easier and better. Information about current battery capacity, cab temperature and machine position is regularly sent to MaxiFleet – regardless of whether the machine is running or not. This allows the operator to see, for example, that the heater is working and has warmed up the cab, that

there is sufficient battery capacity to start the machine, and so on. Most operators have programmed a schedule for the machine’s engine heater based on their usual working hours. But sometimes you need to work at other hours and with the new MaxiFleet functionality it is easy to program the engine heater to start, for example, an hour earlier. The machine’s preprogrammed engine heater schedule can be displayed in MaxiFleet, but changes to this schedule can only be made in the machine. It is also possible to manually switch the engine heater on or off through MaxiFleet.

NEW STUDY QUESTIONS THE CLIMATE BENEFITS OF RECYCLED PAPER

Sustainable Resources, in a press release.

ecycling paper materials may not be all it’s cracked up to be according to a study conducted by researchers at Yale University and University College London. Published in Nature Sustainability in October 2020, the study points out that the recycling of paper materials in particular could have a negative impact on the climate.

recycled paper uses more fossil energy than the production of new paper. Paper recycling uses electricity from the grid or natural gas – energy sources with a high fossil content. Fresh fibre paper can be produced with fossil free energy made from by-products of the wood pulping process.

“These conclusions are in line with what we see on the market,” says Johan Granås, Sustainability Director at Iggesund Paperboard. “It is quite clear that the production of paper or paperboard from recycled fibre generally has a higher climate impact than producing paper from fresh fibres.”

The report adds that without The writers warn that circular radical changes to the energy economy efforts should carefully mix used for recycling, fossil fuel consider the energy implications emissions will increase. “We need of recycling paper products. They to be careful about assumptions conclude that recycling paper is that recycling, or a circular likely to have a limited climate economy in general, will always benefit and a higher climate have a positive effect on climate impact than the production of change,” says one of the report’s fresh fibre-based paper. writers, Paul Ekins of University The main reason is that making College London’s Institute for

Granås points out that Iggesund, for example, emits 33 kg per tonne in direct CO2 emissions when producing Invercote paperboard, while one of Europe’s leading recycled fibre producers emits 294 kg per tonne CO2 emissions, according to the company’s own environmental report. Emissions are even higher among some American ←

THE ONE GRAPPLE DESIGN OF TMK TREE SHEAR

e have left our mark in the tree shear market with our unique one grapple design. Many copies from several different companies only proves that we really made an impact. And now we are ready to change the world of attachments again.

”AND NOW WE ARE READY TO CHANGE THE WORLD OF ATTACHMENTS AGAIN.” Are you tired of dragging a trailer full of different grapples to the job site? Or constantly switching from one grapple to the other? If you answered yes, we might have the best solution for you! This is exactly the point of view where TMK’s newest addition, TMK MultiGrab was born. We were tired of the constant switching of the attachments, just because one wasn’t strong enough and the other was too clumsy for the task at hand. We wanted to create a grapple that would be unique and would bring something new into the market. The MultiGrab was originally designed for demolition jobs, but along the way it has proven to excel in various different jobs as well.

GRAB

MULTI

TMK MULTIGRAB FITTED WITH NTP-10 BRACKET

When we started testing the first TMK MultiGrab prototype, one of the first jobs we took it on was a demolition of a burnt down building. On that job we first sorted the wood scraps from the ruins, then tore down the chimney which had survived the fire still upright. After that we scraped the ruins clean to the plinth as the insurance company wanted to check if that would still be salvageable. When it proved to be also damaged in the fire, we also dug up the plinth so the new house could be then built on top of the original concrete. This was a great job to trial the new MultiGrab as it gave us plenty of more ideas on what were the most important features of the grab. Firstly, it had to be accurate enough to sort the wood scraps from the ruins. Secondly, it needed to have both “the finger tip” grip and the ability to close with a tight enough grip so you could just take any piece of plank in the grab and trust that it will stay in the grip firmly and not cause any danger to the groundwork’s working close to the machine. Thirdly, it had to be solid, but still agile enough to tear down the chimney safely and accurately. Then, when we were cleaning the foundation, we noticed that the grapple must open a fair bit so it moves out of the way and gives you a good visual on what you are scraping. Finally, when the plinth was removed it also had to be sturdy enough to work as a lever to get the big blocks of the foundation dug up. Later along the way we have already used the MultiGrab for digging up stumps from a felling site, digging up boulders from yards, stone wall building with both natural boulders and with square blocks, loading brush into the forwarder and so on. We have even used it to fold scrap cars in half.

The grapple of the MultiGrab is detachable with a quick-connector. In the future we will bring different grapple options to compliment different tasks even better and the grapple can be changed within a minute to suit the current job perfectly. The grapple is designed so that it has a whopping 180° range of motion, and it’s both agile and accurate. The main frame in strong enough to handle fair levering which is often needed in the challenging job sites. Many other optional attachments are in the pipeline for the MultiGrab, as our goal is to make it the perfect Swiss Army knife for excavators in pretty much any job site. The first serial production patch of the MultiGrab M size for excavators 13-25 tn Is just being finished at the factory and the first prototype of the S size for excavators 8-15 tn is going through the manufacturing line in the coming weeks. The wide spread sales of the MultiGrab will start around March, but we are looking for pilot users to help us further improve the MultiGrab. So if you are interested to work in the front line of innovation, now is the perfect moment to jump into the TMK family.

A few weeks ago, just as the days were starting to close in, I had a nice walk through the woods. I wanted to have a look at some felling work I knew had been going on during a period of wet weather and see the results. The area in question had been a fairly even-aged crop of Norway spruce (Picea abies) that had been planted along a burn (no buffers, pre UK Forestry Standard / UKFS). The forester was planning to remove the crop of spruce away from the burn and replant / allow to naturally regenerate with alder, willow, oak and other native broadleaves. This woodland (unlike others nearby) is not designated as a Planted Ancient Woodland Site (PAWS), though it would not be too much of a stretch to assume that this would have been broadleaved riparian woodland in the not too distant past. This area of Hexhamshire is rich with hairy wood ant (Formica lugubris) which relies on sunny

that will be used to build houses, create packaging and generate warmth.

An oak sapling retained above the cleared burn (a Northern / Scottish word for stream). woodland clearings and rides to build its nests using pine or spruce needles. A nice side effect of the felling will be increased sunlight and better conditions for this species over the next few years before the new trees grow. I was really impressed at how little ground damage there had been, given this was down in the soggy valley bottom next to a watercourse. The operators had used brash (tops) from the felled trees perfectly and protected their timber extraction route, which could have easily become rutted. Given that this was such a long, thin strip to work, there would have been a lot of traffic back and forth, especially to the far end to reach all of the timber. The results speak to a well planned operation and conscientious operators keen to achieve best results for the wood.

The forester was not forced into removing the conifers from this watercourse; it was their own recognition of bringing the management of the woodland in line with UKFS and sacrificing a relatively small area in terms of productivity to bring extra benefits. Itâ&#x20AC;&#x2122;s living testament to #ForestsThatWork delivering ecological, economic and landscape value.

In any case, all this is to say; this is what modern day, mixed, commercial forestry can look like. I feel like it needs to be spoken about more widely, as there are so many misconceptions. I also found a really nice rock in the woods and sat on it like Simba on Pride Rock. As a forester itâ&#x20AC;&#x2122;s great to recognise good working practice â&#x20AC;&#x201C; Colin Stevens forestry did the harvesting, managed by Euroforest. Ben Anderton is the Forester at Edwin Thompson charged with organising the felling licences, sale, and with overall responsibility for the forest.

The area to the left of the picture above will continue to be thinned and managed as a productive Scots pine woodland (this area is also a red squirrel stronghold), and this one burn is just part of a much larger forested network that delivers many benefits including growing timber Page 80

FAO FAR SO GOOD Rab Easton visits Douglas Matheson from Walkerburn to find out about his recent purchase of a Fao Far 1542 trailer with the Cranab EC7 from Clark Engineering.

orwarding trailers are more popular today than they have ever been, as demonstrated by the sheer number of models on display at forestry exhibitions. I am pretty sure that if demand declined and no one was purchasing them companies would soon switch to manufacturing other products. In 1985 I purchased my first agri-spec forwarder, a Roadless 75 tractor, with a Chief eight-tonne trailer and crane. This combination was excellent for the type of work being undertaken as it Page 82

could easily be converted back into a skidder by unhitching the trailer and attaching my fivetonne Fransguard three point linkage winch. I was working a thinning roughly two miles away from the main road which could only be accessed via a narrow, twisty, single track road â&#x20AC;&#x201C; it was virtually inaccessible to any vehicle larger than a Ford Transit. Our work involved line thinnings which had been planted in furrows, with every third row being removed. This was commonplace at the time

time as the trees were extracted in full lengths by a skidder and crosscut and stacked manually at the loading bay. Due to the poor access we secondary extracted the timber using our (fortunately narrow) forwarder trailer, stacking in a lay-by on the main road ready for collection. The forwarding and haulage had to be planned with military precision because if any wood was left in the lay-by overnight it would be deemed as communal property by the locals, disappearing in the wee small hours. My trailer extracted a lot of timber over the three years that I owned it and it was definitely a step in the right direction. In some circumstances my daily production increased and the end users were always pleased that we were able to supply clean, stone free timber. Although I have seen Fao Far trailers at forestry exhibitions in the past, they were not a manufacturer that I was familiar with. What I did know, having been a Clark Engineering customer for the best part of 40 years, is that the trailers had to be something special before Clark’s would endorse and distribute them. What I found was that Fao Far are from Southern Poland – a region famous for the quality of its engineering – and the company was formed in 1992. The organisation is owned and managed by Janusz Glajcar, who had been a skilled engineer prior to setting up on his own carrying out repairs and fabricating special projects on behalf of his customers. In 2000, he saw an opportunity to start manufacturing his own forestry equipment. Now, Janusz is the largest private forestry equipment manufacturer in Poland with an impressive 5,200m² manufacturing facility. Fao Far have been increasing in popularity year on year and to keep up with the rising demand they have established a network of distributors throughout Austria, Germany, the UK, and the Ukraine. Richard Gordon from Clark Engineering was in touch to see if I would like to visit Douglas Matheson from Walkerburn, near Peebles as he had purchased the first Fao Far trailer in the UK. This trailer had been fitted with a Cranab EC7 crane by Clark Engineering at their workshops in Parkgate. We arranged a meeting with Richard and Douglas just outside of Walkerburn. Douglas Page 84

had some chipwood that had to be secondary extracted through a farmer’s field and up a forest track to the stacking area. The Valtra T183 Tractor and Fao Far 1542 trailer with the Cranab EC7 7.2m reach crane were perfectly matched and looked in proportion together. Douglas suggested that Richard and I follow him in our vehicles as the extraction site was close by. We turned off the tar road and proceeded downhill through a mature stand of timber on a narrow track, which included a couple of narrow, almost hairpin corners to negotiate on a particularly steep section. I thought it looked pretty tight for the tractor and trailer with standing trees on both edges of the track. There wasn’t room to take a wide swing with the tractor and I thought Douglas might have to complete a few backward and forward shunts, but the trailer’s hydraulically steered drawbar came into its own and made manoeuvring around the tight corners look easy. When we arrived I had the opportunity to have a good look around the trailer and chat to both Douglas and Richard. The trailer, which is manufactured using STENX and HARDOX steel and has a single beam chassis design, is clearly built to very high standards. The bolsters can easily be moved along the chassis for loading different product lengths and they also have hardened large diameter bolster pins that wouldn’t look out of place on a purpose built forwarder. The rear trailer section is adjustable via a sliding inner box section and has a length of 4.45m to 5.5m when fully extended; this means it can easily carry two bays of 3m, a length of timber which is used frequently in the UK. The headboard is impressive, solid, strong, and built to last but still provides a good view of the loading area from the tractor cab. The lights and indicators have a hinged cover for off-road use and fold out for travelling on the main road, while the wiring for the lights is routed along the box chassis and therefore none of it is exposed or vulnerable. The 15 tonne load capacity trailer is 2540mm wide with a generous 700mm of ground clearance and weighs between 4600kg and

www.forestmachinemagazine.com

February 2021

Cranab 28 grapple has a good capacity for chipwood. 5500kg (including loader). Douglas opted for the non–driven trailer as it will primarily be used for secondary extraction; an optional Black-Bruin hydraulic drive is also available on two or all four wheel hubs for increased traction when working on difficult and challenging conditions. The Cranab EC7 crane with the 280 Grapple is everything you would expect from Cranab. The hydraulic pipe and hose layout is excellent as they are clamped along the full structure, which prolongs service life by preventing rubbing and chaffing. Although well routed and protected against accidental damage, all the hoses are easy to access when they need replacing. Cranab use a long kingpost on their cranes and the hydraulic valve block is fixed at the base just in front of the slewing pods. Again this is a highly efficient system which is uncluttered and doesn’t affect vision during loading/unloading. Clark Engineering have added their own extra bracket for protecting the main feed and return hydraulic hoses between the tractor and trailer, and they have also included a deflector guard to the valve chest for extra protection. The stability legs are robust with a large surface area in contact with the ground, providing February 2021

excellent stability even when working on softer soils. The rotating seat mounted EHC controls were installed by Clark’s and they had used the Danfoss lever system. As Douglas started to load the trailer it was obvious the crane was precise and very well set up; movement was quick but smooth with no apparent jerkiness. Douglas admitted to being a bit nervous with us watching him and was still acclimatising to his new equipment; however, given the quality of the product he looked like an operator who had years of experience under his belt. This is a quality trailer that will easily stand up to the rigorous demands of working in the forest. I will leave the final words to Douglas: “I’m very impressed with our new crane and trailer. It was supplied and set up by Clark Engineering from Parkgate near Dumfries and fitted with electric controls in the cab of the tractor. I’ve had it out working on a few sites so far and no doubt there will be many more to come in the future. It’s extremely well built, easy to maintain, and carries a good bit of timber too. I am delighted with my purchase.” www.clark-engineering.com

TOWARDS MODERNISED SILVICULTURE IN SOUTH AFRICAN FORESTRY

Justin Nyakudanga Justin holds a Bachelor’s degree in Technology- Forestry and a Post Graduate Diploma in Business management. He has 20 years experience of Commercial and Extension/Community Forestry.

recently had the opportunity to attend a forestry webinar hosted by the Nelson Mandela University Forestry faculty whose theme was “Towards Modernised silviculture”. I must say the Covid virus has forced us to relook at how we go about our normal day to day activities and find alternative ways of connecting as foresters. Under the old norm such seminars or workshops would have be accompanied with a braai (barbeque) and some potent drink to ease the nerves for the road. Anyway, that’s the past, the webinar was hosted by Dr Muedanyi Ramantswana and attended by more than 300 people from different parts of the continent including African, Europe, and South America. On the programme were seven presentations from; Shawn Biggs from Sutherland seedlings, Jacob Zimbodza a forestry contractor from SMS Contractors, Helgard Steenkamp from Novel Equipment a forestry equipment manufacturing company, Shaun McKenzie from Silvix a company that manufactures herbicides and tree planting & weeding hand tools, Nicky Gwende from Thuthungani silvicultural contractors, Dean Da Costa from Mondi South Africa and Professor Saulo Guerra from Brazil. The concept of modernisation silviculture in South Africa includes updating forest operations in

February 2021

terms of both mechanisation and other modern systems improvements with the goal of improving wood/fibre quality and reducing production costs to remain locally and internationally competitive. So why the drive towards modernised silviculture in South Africa? It is because silviculture operations in South Africa have been traditional and labour intensive, with methods being region specific and haven’t changed much for the past 2030. For example, according to Jacob Zimbodza research about 56% of the land preparation in South Africa is manual, 10% motor manual and only 34% mechanised. However, the changing labour demographics, climate change, tight labour legislation, timber price competitiveness, safety and ergonomics requirements and artificial intelligence requires that South African forestry industry relooks at how things are done. Therefore, silviculture operations in South Africa presents the opportunity for the next quantum developments in the forestry industry. DRIVERS OF MODERNISED SILVICULTURE IN SA What are the drivers of modernised silviculture in South Africa? According to Mondi’s Dean Da Costa these include; • An aging rural workforce, with an annual 5% decline in the rural population due to rural Page 87

•

• • • • • •

to urban migration and natural attrition. Young adults do not look as forestry work as a job of choice. High labour turn over (20-30%) and absenteeism. Due to the fact that the forestry work is manual and repetitive, forestry workers are easily fatigued and tend not to turn up for work. The impact of HIV/AIDS, with about 30% (through tests) of the forestry workforce infected. Low productivity and quality challenges as a result of manual operations. Poor ergonomics and posture as manual work requires that one bends or carry heavy loads. Social status (esteem) and education. Young high school graduates look down on manual forestry work. Migration patterns in the South African labour market. Sectorial wage determination, labour legislation and social grants. The introduction of the minimum wage has made labour very expensive and this impacts on profitability of forestry operations and the recipients of social grants don’t feel motivated to seek work opportunities.

FACTORS ENABLING SILVICULTURE MODERNISATION So, what are some of the requirements or enabling factors for a forestry company or tree farmer to be able to effectively modernise his/ her forestry operations? According to Nicky Gwende from Thuthungani Contractors, there are 4 keys to successfully transition from manual to mechanised silviculture operations in the South African context from a contractor’s perspective. These include the following; •

•

Establishing operating procedures – this involves the establishment of standard operating procedures for the silviculture operations and involves high level planning, risk analysis and the safe movement of people. Machinery to be deployed – it important to understand the slope limitations of the machinery to be deployed to avoid roll overs or tipping and to maximise its functionality in any given environment. People – it is paramount to get the buy in of the people involved in the operation. Training

Page 88

of the operators and technicians is also key to the success of the operation. • Support from the client – the grower company/farmer should also be willing to assist the contract were possible in order to achieve sustainable results. Shawn Biggs from Sutherland Seedlings further cited the deployment of high-quality seedlings propagated in Elle pots infield as key to ensure survival of seedlings and maintaining high tree stocking after planting. Ello pots are also tipped as being more compatible with mechanical planters used in the South African silviculture environment. Ello pots are better compared to the normal pine bark medium based plastic seedling trays because; • • • • • •

They have good air circulation Have stable substrate which does crumble Have good drainage. Have better field establishment. Higher density/weight compared to standard loose filled plugs Have a greater infinity for water once planted

CHALLENGES TO MODERNISATION OF SILVICULTURE IN SA Some of the challenges to modernisation and mechanisation of silviculture in South Africa according to Helgard Steenkamp include the following; •

•

Paradigm shift - modernisation of silviculture requires the renewal of the mind as some people still prefer the traditional and conventional ways of doing things. Residue and stumps – stumps and residue limit the movement of machines infield and are energy hungry (high diesel consumption) activity when being removed. Stumps also decrease the area to be re-planted leading to underutilised land due to inaccessibility. Environmental considerations – such as carbon emissions from machinery.

Helgard suggested a Web based solution application to bring precision to mechanised planting operations based on digitisation and telematics. Each seedling planted is therefore geo referenced which in turn makes follow up mechanised operations such as weeding and tree felling easy to manoeuvre. His company Novel

I was thrilled when Willie phoned to let me know he was starting a mature oak thinning near Perth using his Tigercat 615E grapple skidder and his Komatsu 895 forwarder. I was looking forward to seeing Willie and his team and I had been assured I would get to try out both machines for myself. Willie was working on a private estate with approximately 70 large trees that required felling and extracting. The branches and crooked timber were to be cut into 3m lengths for firewood, while the straight stems would be used for sawn timber, beams or veneer.
