A visit to the 2024 Queensland Tree Climbing Championship was an incredible introduction to the spectacular world of climbing competitions. Image: TF
A competitive nature
I’m really looking forward to the Asia Pacific Tree Climbing Championship.
Fingernails are being chewed and there’s a great deal of nervous fidgeting as I write this. Organisers are awaiting final approval for the dates, and the excitement and enthusiasm of all involved is contagious.
I’m a new fan of climbing competitions. I had such a good time during a very brief visit to the 2024 Queensland Tree Climbing Championship that I’m now a big supporter, and I’m just as keen to see the dates of the Asia Pacifics confirmed and announced as seasoned climbers and officials.
The Queensland Arboricultural Association is hosting the event, and they’re not helping by geeing me up with vivid descriptions of how great it will be, and by saying how they really hope the magazine will be there.
At this stage, it’s my intention to attend, shoot photos, talk to as many climbers
and volunteers as I can, try and get some inside info on the upcoming ITCC event, and hopefully bag a few stories.
Is it any wonder I’m excited?
As soon as the final details are available, The Australian Arbor Age will post them on the website and the usual social-media channels, and we’ll be doing our best to get everyone keen and on the ground for the big weekend.
Right now, the dates are forecast to be ‘late May’ and the venue will be at Capalaba in Brisbane’s south-east. It might be worth tentatively blocking out those last couple of weekends and making some loose travel plans.
The climbers have to make a big commitment to compete. Not just financially, but in time and personal sacrifice. The volunteers do the same. The organisers face a huge uphill struggle to not only run the events, but to make them worthy of the international status they represent. Acknowledging that,
let’s rally round and show some support.
Try and get to the event, even if it’s only for a few hours, and enjoy the camaraderie and athleticism that goes with competition at the highest level – no pun intended. Just showing up and spectating will be hugely appreciated by everyone involved.
If you’re in a position to help with any aspect of the event, whether it’s setting up and packing up, paperwork, or perhaps officiating, get in touch with the QAA and put your hand up. The staff there will love you for it, and you’ll be joining a tight-knight group of true enthusiasts and professionals with a passion for trees and climbing.
The QAA website address is qaa.net.au. That sounds pretty damn good, doesn’t it? You bet it does.
See you there.

Significant trees
The Lone Cypress
A famous landmark on California’s 17 Mile Drive in Monterey.
With what seems to be a tenuous hold on a granite headland overlooking Carmel Bay, California, the Lone Cypress is believed to be around 250 years old. The Cupressus macrocarpa has survived centuries of Pacific winds and salt spray, and is one of America’s most photographed trees.
A stone retaining wall was constructed around its base in 1941 to protect its root
system from erosion, and cables were installed in 1948 for support. The tree was fenced off from the public in 1969, and in 1984 an arson attack left the Lone Pine scarred but undaunted.
A storm in 2019 removed a branch, noticeably altering the tree’s appearance, but it remains a favourite postcard subject and a major tourist attraction.

Moni-tour ’24
Upskilling for excellence in tree-care equipment.
In December 2024, Monitor Industries hosted an exceptional week-long event at its head office in Tamworth, NSW. Over 60 staff members from across Australia – Melbourne, Brisbane, Sydney, Perth, and Tamworth – came together for Moni-tour ’24.
This event marked a significant milestone in Monitor’s ongoing commitment to upskilling its team, and was supported by Morbark, a leading American manufacturer of Morbark woodchippers, Rayco stump grinders, and Boxer tracked loaders.
In-depth product training
Representatives from Morbark delivered a comprehensive series of workshops and hands-on training sessions focused on the latest advancements in tree-care machinery, specifically their impressive new enhanced BVR wood-chipper range, which is set for release in Australia in the near future.
Monitor’s service technicians, workshop managers and product
specialists delved into the nitty gritty of wood chippers, stump grinders and tracked loaders, from torque settings to bolt sizes, types of bearings and why they’re used. A key takeaway from Alex Enticknap, Branch Manager VIC, was that “…there’s a lot of intricate detail in these machines. The tolerances, lubrication schedules and torque settings must be right. If not, the longevity of the machine is greatly affected.
“You really need specialist technicians to service them – people who can also offer guidance to customers on how to get the most out of their machine.”
Demonstration and innovation
Throughout the week multiple hands-on machine demonstrations and tests took place, with a focus on the soon-to-bereleased and much anticipated range of Morbark BVR wood chippers.
This was a fantastic opportunity for both Morbark and Monitor technicians to make sure they were suitable and ready to tackle Australian demands.
A key takeaway after getting up close and personal with the new BVR range for Blake Harwood, Business Development Manager QLD, was, “…the improved efficiency and cutting-edge technology that sets the BVR series apart from others in the market. An example is Morbark’s proven and patented ZeroClutch technology that features an integrated drum-speed sensor that monitors the drum speed and will not allow the clutch to engage if material is lodged between the feed wheel and drum, or if the discharge chute is plugged”.
Tim Joyce, Founder and Product Manager, discussed other notable innovations including “…the infeedmounted control panel that provides a more convenient location for operators, a side-load anvil, a 360-degree manual swivel discharge chute with multiple locking positions for greater control over chip discharge, and a three-position electronic control bar with dual safety pull cables”.
Kahi Puru gave a powerful speech on workplace health and safety.
“The hands-on wood-chipper demonstrations were appreciated by many of the team, particularly those who had not previously seen these machines in action,” said Tim. “There’s nothing like experiencing and feeling the power of a chipper in action, and watching and smelling the fresh wood chips flying.”
After thorough testing and discussions, it was clear the BVR wood chippers were more than ready to make an impact on the Australian market. These chippers are designed to meet the specific needs of arborists here, with a focus on both durability and performance. The local consensus from the testing phase was that the BVR’s combination of power, versatility, and ease of use positions the new chippers as a potential industry game-changer.
Growth matched by development For Monitor Industries, Moni-tour ’24 was more than just training: it was a demonstration of the team’s dedication
Hands-on demonstrations were appreciated by everyone.
to providing the best possible service and support to its customers. With an emphasis on continuous improvement, the event underscored Monitor’s commitment to building a highly skilled and knowledgeable team. This aligned with the overarching goal of offering unmatched expertise, not only in its renowned spider-lift range, but now also in the growing tree-care equipment sector, following the company’s recent merger with heavy-machinery giant, Global Machinery Sales (GMS).
Ben Joyce, CEO, reflected: “We have run Moni-tour events for many years now, each with a different focus. I felt the tree-care space was a really important area to provide training on this year to ensure our team can match the renowned support we offer for our EWP range in the tree-care space, too.”
The event underscored Monitor’s commitment to building a highly skilled and knowledgeable team.

The week’s activities weren’t limited to product training.
A notable highlight was the appearance of Kahi Puru, a Paralympic powerlifter and workplace health and safety advocate, who shared his personal story of resilience. Kahi’s moving speech served as a powerful reminder of the importance of safety and well-being in the workplace, and what can be achieved with dedication and commitment.
“It was a very moving speech,” said Ben. “You could tell it really resonated with the team and was a great way to celebrate the work everyone has been doing in terms of keeping our workplace safe and committed.”
Past, present and future
The event concluded with an endof-year evening gathering, where the Honourable Kevin Anderson MP addressed the attendees, speaking passionately about the importance of upskilling local communities and supporting businesses within the region. Throughout Kevin’s speech he described, “What stands out to me about Monitor Industries is its dedication to upskilling its workforce. It’s clear that when businesses invest in their people, the community thrives.”
With speeches from Monitor’s CEO, Ben Joyce, Founder and Product Manager, Tim Joyce, and Morbark representative Lou Hicks to follow, discussion covered the year that’s been, where the company is heading in 2025, and the exciting new Morbark BVR wood chipper range to be launched in Australia soon.
Looking forward
For Monitor Industries, Moni-tour ’24 was an outstanding success, showcasing its continued focus on professional development, customer satisfaction, and product excellence. As the company looks ahead, it remains committed to maintaining its position as an industry leader, empowering staff to offer the best support and service to customers across Australia.
“We’re excited about what lies ahead,” said Ben. “From new product launches to enhanced service packages, we’re committed to delivering exceptional value to our customers across Australia and beyond. As we celebrate nearly 30 years in business, our focus remains on supporting our clients and driving the industry forward.”
Monitor Industries is poised for an exciting year ahead, driven by a commitment to knowledge, skill, and innovation.
Monitor staff and Morbark representatives wrapped up a fantastic training week.
The Honourable Kevin Anderson MP encouraged staff to continue to strive for excellence.

Reaching new heights
Husqvarna’s continuing support of competition climbing has helped Australia achieve international recognition.
Tree-climbing competitions aren’t new in Australia, but competitor numbers have grown in recent years, and with climbers like Barton AllenHall, Jack Lewis, James Gigliottii and Alana Murray scoring high on worldchampionship rankings, the glamour end of the sport is going well.
But the grass-roots level – where future international contenders will make their start – is continuing to gain momentum, and one thing that seems to be constant in the Australian climbing scene, from the most fundamental ‘local’ competition through events like Women in Arb and on to the sharpest and elite international contenders, is support from Husqvarna.
Officially
Husqvarna’s spokesperson, Marketing Manager Vienna Spence, offered a fairly modest comment on the situation.
“These events are a fantastic opportunity for Australian climbers to showcase their skills, and at the same time help to inspire the next generation. Husqvarna is proud its support helps showcase our industry and its importance within the community.”
While there’s no doubt of the truth of those statements, they don’t really present the depth of Husqvarna’s support of climbing competitions, competitors, and the sport in general.

good position to explain the importance of that support to climbing nationwide.
Team effort
Adam Lovering is the manager of the Australian team which competed at the 2024 world championship. He’s been a working arborist for some years, and his company, Impact Arbor Tree Service, is based on the NSW Central Coast. Aside from his role with the Australian team, Adam is also involved with the NSW arb committee, and he’s been around the competition scene for long enough to have seen first-hand the effect of Husqvarna’s involvement.
“Husqvarna is one of the most important pieces in Team Australia,” the easy-going New South Welshman told The Australian Arbor Age, “but it’s not just Team Australia. Husqvarna supports a large number of competitions around the country.
“For the associations just to be able to run the competitions, then send people to the nationals, and ultimately
field teams at the Asia-Pacifics and internationals…it’s Husqvarna’s support that’s helping to keep the community competitions going to enable us to get climbers to the big stage,” he said.
In the beginning
Adam’s personal support for Australian competitors began some years ago and has grown over time.
“I have a side company called The Climber Cartel which was producing T-shirts and rope bags and so forth,” he related. “I’d seen how much work Jamie Boston and a few other boys at the time were putting in to go to all these competitions around Australia, and I started supporting them individually.
“Through my sponsoring those guys, I knew a climber called Mark ‘G-man’ Gistitin. In my eyes he was probably the best climber around at the time, and he went to the US and finished sixteenth or seventeenth in the world. When he came back I asked how come he’d finished so badly, and he told me: ‘Mate. When you
get over there it’s a scary place. There’s no one to talk to’.
“It’s an individual sport, so it’s hard if you don’t have a team backing and supporting you the whole way.
“Once a few of our climbers made it to international level, we sort of came together trying to get some sponsorship and to bring the team together as a group. Because everyone came from different areas all around the country, once they got to the international level, they didn’t really fit in together, if you know what I mean,” remembered Adam. “Jamie Boston and I tried to unite the individuals as a team to represent Australia.”
Husqvarna
Adam and Jamie enjoyed some success, but then there was a shift in Australian competition climbing a few years ago.
Adam explained: “For the past three or four years, Husqvarna has jumped on board big time, helping financially with the things we couldn’t do. Husqvarna

paid for a lot of us to fly up to Brisbane two years ago to have a big training camp just before we went to the world championships.”
It was the kind of support which allowed bringing the climbers together as a team, and focussed their preparation, skill development and sharing techniques to prepare for highlevel competition.
“We never would’ve been able to come up with the finances to be able to do that ourselves,” Adam said quietly. “Husqvarna definitely supported us heaps with that.”
Jamie B
When Adam said, “They paid for a lot of us to fly up to Brisbane…” the setting for the training was the property of good friend Jamie Boston.
Jamie has a string of internationals and titles to his credit – most recently a win at the Queensland Tree Climbing Championships – he’s a Husqvarna H-team ambassador, and he and his brother run Boston Tree Care near Brisbane. Jamie is also the current president of the QAA.
“In 2023 Husqvarna flew everybody that was part of the team up to my place in Brisbane where we hosted a training camp. Then Husqvarna brought in a
videographer to film and do interviews to build the team brand and image to help us gain other sponsorship to help with the rest of the funding,” he said, clearly appreciative.
Vital support
Like Adam further south, Jamie is in a good position to appreciate Husqvarna’s involvement with the climbing fraternity.
“From the QAA’s perspective, we can’t operate and run events without help from sponsors. We’re a not-for-profit organisation,” explained the very likable and enthusiastic Boston. “But it’s not just the QAA Husqvarna supports. It’s the wider Australian arb community as well. None of us could give back to the industry without the support of Husqvarna,” he summed up.
Jamie’s also the current captain of the Australian tree-climbing team, and international competition is expensive. Attending the AsiaPacific championships or the world championships takes a huge commitment, both personally and financially. For most climbers it’s not only the cost to travel and compete, but also the lost income from time off and not working. Jamie cites Husqvarna’s generosity as vital to both
his and the Australian team’s ongoing representation and competitiveness at those events. Husqvarna awards individual climbers in the team a cash grant which goes a long way to making attendance achievable, as well providing backing to the whole team to ensure the climbers have real support in their efforts.
But, as Adam pointed out earlier, it’s not only big, high-profile events which get Husqvarna’s attention.
“For a number of competitions around Australia, most of the time the prizes are donated by Husqvarna,” Jamie pointed out. “Whether it’s e-vouchers, equipment, prize money…it’s a mix of product and cash or e-vouchers for the events.”
All for Aus arb
QAA will be hosting the Asia Pacific Tree Climbing Championship and New Zealand the International Tree Climbing Championship in 2025, and Husqvarna is the major sponsor for both events.
Jamie offered an overview of the way he sees Husqvarna’s involvement with arboriculture in Australia.
“It’s a ‘no-question support’ attitude,” he said. “Husqvarna’s open to the support of all practical arb throughout Australia.”
Ufkes Greentec chippers
Does Ufkes Greentec machinery stack up against its competition? The people who use them should know.

As a subcontractor working full time in tree care, Russell Fray has used a few different chippers and machines. A Cert 3 arborist, he now spends the majority of his working days with The Climbing Dutchman, a Mornington Peninsula-based arboricultural business, which keeps him fairly busy.
Russell is big fan of the Ufkes Greentec Jaguar 40 chipper and its 16" feed.
Experience
“I’ve worked behind the two main American-brand chippers with other companies,” the Mount Eliza-based arborist told The Australian Arbor Age.
“I’ve had enough experience with those to be quite confident in knowing their capabilities and how to operate and maintain them.
“These days I’m onsite with the Jaguar 40 most days, usually running the crew. I’ve probably been operating and working with that machine for close to 18 months.”
During that time Russell has developed a healthy respect for the individual machine and the Ufkes Greentec brand.
Impressed
“The Jaguar 40 is definitely a good thing,” he said.
“I guess the difference between this particular model – and a lot of the range from Ufkes Greentec – and other chippers is that you can customise them with different add ons and have different set ups.
“The machine I’m working with has an 8.5-metre crane grab attached to the chipper. It’s a hydraulic, joystickcontrolled crane that’s able to grab branches and logs and bring material close and feed it in to the chipper. That’s probably the main point of difference with this particular machine compared to everything else that’s on the market. It’s able to feed itself using a hydraulic arm with a grab, and it’s sort of like two machines in one.
“A lot of other people may be set up with a traditional chipper and they’ll use a skid steer, small loader or excavator to bring the material to, and feed, the chipper. The crane grab on the Ufkes Greentec machines enables us to be able to do that with a single, all-in-one package.
“The Jaguar’s crane has good lifting capacity, so if the tree or branch will fit through the 16" (40cm) feed opening, you can pretty much grab it and feed it in in one go.”
High efficiency
Russell pointed out a substantial increase in efficiency due to the crane and chipper being a single unit.
“There’s no second machine – skid steer or excavator – involved,” he explained.
“We can run a much smaller crew, and achieve a lot more in a day, because the machine does all the work. It’s a faster, smarter way to work.”
Russell went on to outline the additional cost of having an extra
machine on site – another trailer, tow vehicle and driver – and the possibilities afforded by the Ufkes Greentec set up.
“We wouldn’t normally do it, but there have been specific jobs where I could turn up on my own and handle a chipping pile someone’s left. I can just work my way through it with the crane grab, pretty much standing behind the chipper and having the machinery do all the work.
“It’s easier to fill bins with mulch and it’s easier to process material. It’s more efficient and it’s a lot safer.”
Tough as
While the efficiency and safety offered by the Jaguar is obviously a high priority, the durability of the Ufkes Greentec gear must also be a big consideration. There’s no gain in a machine which will run at high speed but won’t run for long because it constantly needs repair.
Russell had no reservations in that area.
“The Ufkes Greentec machinery is better engineered,” he said, clearly confident in his assessment. “It’s a heavier build quality for the whole unit.
“Everything, from the quality of the steel to the painted finish, stands up well to the daily wear and tear this kind of work throws at it. We’ve never really had downtime due to breakages or with the way the machines have been engineered or constructed.
“The dual-axle trailer is a good example,” he continued. “It rides better than a single-axle trailer. We have a medium rigid truck pulling the chipper, and our set up is probably around 6.5 tonnes on the trailer. I can cruise on 100kph on the highway, no worries. I don’t even know the chipper’s on the back.
Bottom line
“You don’t realise the capabilities of the Ufkes Greentec machinery until you’ve worked on a job with it,” said the Victorian. “It’s not only doing the job of an excavator, skid steer or a loader saving the heavy lifting, but we can use it as a crane. As long as we’ve got the reach, we can crane things away with the climber still in the tree. It means we can work safer, minimising the impact of material falling on the ground or having to set up rigging and so forth.
“There’s a lot of advantages with the Jaguar 40. You can get a lot done in a day without the operators breaking a sweat.”
The 952MEGA has plenty of horsepower and is easy to transport.
Second opinion
Another happy Ufkes Greentec owner is Mark Maiden of MJM Forestry Service in Gippsland, Victoria.
Mark, an owner of the business, has around 60 dozers, excavators and other machines in his fleet, but only the one chipper – the Ufkes Greentec 952MEGA with a 22" x 41" infeed and 400hp.
We wondered what led a bloke with so much heavy-machinery experience to choose Ufkes Greentec.
“I just wanted something that was big, horsepower-wise, but easy to transport,” said the straight-shooting Victorian. “And
the expense of a crew and another truck with a driver and loader.
“It has its own crane, so it’s all pretty self-sufficient,” he explained. “It eliminates floating costs and the cost of an excavator. We can go out with just that machine and a tipper, and it can be a one-man band. We can pick up a log and put it through the chipper or whatever needs to be done.
“Getting good personnel these days is getting harder and harder. If we can have one man do the whole job, it’s quite good.”
Mark was happy with the power, too.
Greentec stood up to it. It’ll do 20 cubic metres of chips in about 12 minutes if you’ve got the right material feeding it.”
A hydraulic, joystick-controlled crane can grab branches and logs and bring material close, then feed it in to the chipper.
Chippers, grinders and clean-up options
Keep up the grind
Site and stump clearing is an often overlooked, but vital, aspect of construction preparation. No job is exactly the same, so contractors need robust, reliable and adaptable equipment that can tackle any challenge.
The SC48TX Stump Grinder is the latest culmination of Vermeer’s continued innovation. Images: Vermeer Australia
Powerful equipment that is flexible and suitable for a variety of different situations, without sacrificing efficiency and productivity, is essential for arbor-industry professionals.
Vermeer’s SC48TX Stump Grinder is the latest addition to its stump grinder line-up, and it’s the ideal addition to any landscaper’s, arbor professional’s or rental-equipment provider’s fleet. The machine’s compact size allows it to manoeuvre through tight jobsites without sacrificing its robust cutting capabilities, allowing it to take down large stumps with ease.
An experienced provider
Vermeer has been in operation since the late 1940s and has grown into a major powerhouse of an equipment provider, recognised across the world.
In 1957, Vermeer created the industry-leading design for the stump grinder using a horizontal cutting motion that remains the most efficient and reliable design to date.
When testing the initial model, an operator accidentally caused the cutting wheel to move horizontally – not vertically as planned. They found this motion cut the stump more efficiently and decided to further develop this design.
After Vermeer brought the first commercial stump grinder to market, it continued to develop new features and models to better equip customers in their daily work.
Never get stumped again
The SC48TX Stump Grinder is the latest culmination of Vermeer’s continued innovation and iteration.
“ ” A beltless design provides excellent cutting strength while minimising wear and tear
The machine’s low ground pressure and narrow footprint give operators unparalleled access to difficult jobsites.
Designed to help contractors systematically cut stumps of all sizes, the 48hp (36kW) diesel engine enables optimal fuel economy, durability and performance.
The beltless direct-drive system delivers power from the engine to the cutter wheel through a pair of gearboxes connected by a driveshaft. This beltless design provides excellent cutting strength while minimising wear and tear, meaning contractors can expect minimal maintenance costs.
Despite its power, the machine’s low ground pressure and narrow footprint give operators unparalleled access to difficult jobsites. The SC48TX’s ability to retract to only 89cm (35 inches) and then extend the tracks to 124.5cm (49 inches), allows operators to work in previously unreachable areas.
The machine also sports Vermeer’s unique two-sided cutter-wheel design, minimising the recirculation of material and maximising grinding efficiency.
Additionally, the SC48TX offers further flexibility with its optional, full-function remote-control mode, which allows operators to use the equipment from a distance to improve safety and visibility.
Support guaranteed
Contractors can work with confidence knowing the SC48TX’s CAT engine is supported worldwide with three-year service coverage.
Additionally, Vermeer offers extended service coverage, preventive maintenance, and its Vermeer Confidence Plus® asset-protection program.
Vermeer Australia offers more than just the latest in high-quality, highperformance equipment. With its team of industry experts available across 13 metro and regional branches, the Vermeer Australia team provides leading after-sales support and service.

Chippers, grinders and clean-up options
Rayco
Arborists’ go-to stump grinders.
Stump grinding can be tricky, demanding precision and power to get through tough stumps without damaging the surrounding area. When it comes to choosing the right equipment, the Rayco RG37 Trac stands out as an efficient, compact machine that combines agility with strength. It’s ideal for arborists like Jake from Stump N Grind, who need reliable machinery to get the job done.
A journey in arboriculture
For Jake, owner of Stump N Grind, his journey in arboriculture began in 2000 and 2001 at Wollongbar TAFE.
Over the years, Jake gained extensive experience in felling, pruning, and climbing, working with various local arborists in the Northern Rivers region of NSW. A significant portion of his work was done alongside Swing Tree Service, where Jake honed his skills and built his
reputation as a reliable arborist.
In 2007 Jake took his first step into the stump-grinding business by purchasing a Rayco RG1625 Super JR, complementing his tree work. Despite the job’s simplicity, Jake quickly realised there was much to learn about maintaining the machine’s efficiency, avoiding underground damage, and using proper screening tactics to protect property. The time spent keeping the machine sharp, planning stump-removal approaches, and managing job schedules gave Jake valuable insights into the business.
After the COVID-19 pandemic hit, industry demand led Jake to shift his focus further toward stump grinding for private and commercial jobs. As his workload increased, so did the need for better machinery. This led him to upgrade to the RG35T, marking a significant improvement from the RG1625. The new machine brought with
Rayco stump grinders improve efficiency, reduce downtime, and handle even the most demanding jobs with ease. Images: Rayco
it more power and allowed Jake to focus almost entirely on stump grinding. Jake’s success in the industry came down to his reliability and transparency as a business owner, as well as his having the right tools and machinery on hand to tackle all sorts of jobs with precision.
The Rayco RG37T
When it came time for another upgrade, Jake turned to the Rayco RG37 Trac, a compact but powerful stump grinder that ticked all the boxes for his growing business. After putting 1400 hours on the RG35T, it was still working well, but Jake knew the wear and tear from his busy schedule would soon catch up. Upgrading to the RG37T allowed Jake to minimise downtime, increase productivity, and meet the demands of his clients.
The RG37T has proven to be a versatile, compact stump grinder, ideal for
both small residential jobs and more extensive commercial work. Its compact size (890mm wide) allows it to fit through gates that are typically 900mm wide, a critical factor when working in suburban areas with tight access points. This feature sets it apart from other similar-sized stump grinders, which often struggle to fit through narrow entrances.
With a cutting depth of 450mm and a hydraulic backfill blade, the RG37T excels in removing stumps completely, ensuring builders can lay foundations or install services without any obstruction. Jake praises its maneuverability and lightweight design, which enables it to work on well-built decks, paved areas, and other sensitive environments without causing damage.
Key features
When touching on the RG37T features with Jake, he explained, “The RG37 is probably one of the most useful machines.”
So, what makes the Rayco RG37 Trac such a standout option for arborists and contractors?
• Compact design and excellent traction: the rubber-track undercarriage on the RG37T provides superior traction, allowing it to operate efficiently on uneven, muddy, or slippery terrain. The machine’s short track base ensures easy maneuverability, reducing turf damage often seen with longer-track machines. Its counter-rotating tracks make it possible to turn in place, a useful feature when repositioning for large stumps or working in confined spaces.
The compact size of the RG37 allows it to work in suburban areas with tight access points.
• Power and precision: the RG37T is powered by a 37hp Vanguard engine, which provides ample power to tackle tough stumps while remaining fuelefficient. Its 43.8cm x 2.5cm cutter wheel and 44.5cm cutting depth give it the capability to handle both small and large stumps, cutting deep enough to remove stubborn roots.
• Swing-out control station: Jake particularly appreciates the swing-out control station, which offers excellent visibility while cutting and ensures precision. The control station can swing back in line for easier travel through gates or when repositioning the machine, adding to its overall flexibility.
• Two-speed travel and hydraulic backfill blade: Arborists like Jake can move quickly between jobs and easily clean up mulch with the backfill blade, saving valuable time on each job.
Monitor Industries for stump grinders
Jake’s decision to choose the RG37T was primarily based on the machine’s reputation and capabilities, but Monitor Industries, the company that distributes Rayco stump grinders in Australia, has provided exceptional support. Although Jake handles most repairs and maintenance himself, he values the fact Monitor Industries offers professional and helpful service.
Having access to a knowledgeable mechanic has been invaluable for Jake, especially when troubleshooting technical issues that aren’t easily found on YouTube or forums. The timely support and quick dispatch of spare parts from Monitor Industries has ensured Jake’s downtime has been kept to a minimum, and kept his business running smoothly.
What’s the verdict?
For arborists and contractors looking for a versatile, reliable, and compact stump grinder, the Rayco RG37 Trac is an excellent choice. Its combination of power, maneuverability, and compact design makes it an ideal machine for various job sites, from small suburban yards to larger commercial projects.
Jake’s experience with the RG37T showcases its ability to improve efficiency, reduce downtime, and handle even the most demanding jobs with ease. Whether just starting out or looking to upgrade, the Rayco RG37T is a stump grinder which can be relied on.

Forest Centre to distribute Green-Tec TH3
Green-Tec, a Terex brand specialising in tree-care and vegetation-management solutions, has endorsed Forest Centre as its Australian distributor for the TH3 Tree Care Handler.
Building from experience in forest harvesting and haulage equipment, the decision to include purpose-built solutions for mechanised tree care in Forest Centre’s product range was borne from curiosity and a frustration with receiving requests for equipment combinations that didn’t seem to be readily available.
“It was a bit of a slow burn, and perhaps even a little early for our market,” explained Forest Centre
Director, Rey Kell.
“Going back to around 2010 to 2015, some of the forestry attachments we had available at the time could absolutely cut and handle timber, but it became obvious to us that this didn’t always make them a great match to the needs of tree-care and vegetationmanagement contractors.
“Tree harvesting out in the forest and tree dismantling for removals are similar, but not the same.”
Wide-ranging range
Fast forward a few years – with thanks to some of Forest Centre’s keen-eyed customers and Rey’s persistent market research into product development and utilisation abroad – and there’s now a strong population of purpose-built attachments from various European brands working Australia-wide in tree-care tasks, all distributed from Tumut in the Riverina region of New South Wales.
Image: Awesome Earthmovers
“We’re extremely grateful to have been well received by tree-care and arbor-related businesses both big and small here in Australia,” said Rey. “Forest Centre’s now supplying a range of grapple, saw and shear attachments for everything from compact skidsteer loaders through to truck cranes, telehandlers and large excavators.
“During this time we’ve established great working relationships with some of the key players in arboriculture,” he added, “as well as dealers for various carrier machines, and it’s exciting to be able to move into 2025 and offer a complete working package to existing and new clients across Australia.”
The package which is making Rey smile so enthusiastically is the Green-Tec TH3 Tree Care Handler.”
TH3 Tree Care Handler
Featuring a compact design, fourwheel steering and up to 15 metres of effective reach with the telescopic
stick boom and Vosch grapple saw, the TH3 is a brilliant option to complement any fleet for quickly and efficiently getting through large work volumes in roadside or storm clean-up applications.
Features of the TH3 include:
• A cabin with 30-degree tilting and elevation to 5.3m above ground level
• Four-wheel steering with a 4.5m turning radius
• Machine width: 2.72m
• Machine length: 9.52m
• Machine height: 3.43m and
• Operating weight: 21,900kg.
“The standard Vosch grapple saw on the TH3 is a bit of a bonus,” quipped Rey. “Being the Australian dealer for Vosch since 2017, Forest Centre is already very familiar with these grapple attachments on excavators.
“Contractors particularly appreciate the simple, robust ¾” harvester saw system and unique 20-metre safe working zone when cutting –
compared to 90 metres with nearly all other grapple saws,” he added.
Wide coverage and support
The Forest Centre crew is a small team based in Tumut, NSW, and from its earliest days having a sister company in timber harvest and haulage, the company’s been on both sides of parts and service when something comes up and distance is a challenge.
“We strive to uphold our reputation for fast turnaround and outside-thebox solutions where needed for parts deliveries,” Rey pointed out. “For technical needs further afield we’re fortunate to have service partners in five states, mostly from forestry backgrounds.”

Forestry equipment
Telematics
Your link to forestry-equipment cost savings.
To remain competitive, successful forestry management is always trying to find ways to boost production or reduce expense. To put it more simply, either sell more or spend less.
The key to finding ways to do either is more information. Telematics, or remote reporting of equipment information through satellite or cellular service, can generate the information a business needs to sell more and spend less.
Cellular versus satellite
Many forestry-equipment manufacturers now offer a telematics option on their equipment, and on some machines it’s a standard feature. Telematics installed by the OEM as standard equipment will often be less expensive than a retrofit, and it’s certainly hard to beat the convenience. However, a quick search of the Internet will turn up aftermarket telematics vendors that can provide varying degrees of information.
At its heart, a telematics system includes hardware and software that together provide information ranging from the location of equipment all
the way up to complete diagnostics of all machine components, including fault codes, event codes, preventive maintenance due, and so on. Many
Telematics can generate the information a business needs to sell more and spend less.

No more missing a scheduled service or running with dirty air filters.
of these systems include a controller installed on the machine that communicates via a satellite link to the vendor or manufacturer’s computers. The equipment owner is then able to access the information on a website from anywhere in the world, even using a smartphone.
Some telematics systems use cellular service rather than satellite. This can be less expensive depending on options, but it may provide less reliable communication due to gaps in cell coverage.
Reduce spend
There are some different ways telematics can help spend less on equipment.
• Reduce idle time: for an average size machine, idle time is the equivalent of throwing a $2.00 coin out the window every minute. With VisionLink®, the user interface for Caterpillar’s telematics system Product Link™, a Cat® customer learned an operator had run a mid-size dozer for 40 hours one week, with 16 of those hours running at low idle. With the dozer consuming about five litres of fuel per hour at low idle, and with diesel fuel costing roughly $1.50 per litre, the
operator cost his company $120 that week. More importantly, he added 16 unproductive hours to the machine clock, and the machine will be due for its next scheduled service sooner.
• Eliminate catastrophic failures: if the telematics system is capable of ‘talking’ to the machine’s electronics, it can report Level 2 and Level 3 fault codes, emailing them directly to the owner or fleet manager. Recently, a Cat customer had a machine with three Level 3 fault codes for the transmission overheating. Not only did he receive three email notifications, Caterpillar personnel called the customer by phone to ask him to shut down the machine. The problem was corrected and catastrophic failure of the transmission was avoided. The customer found the operator had deliberately overridden the fault codes and continued to operate the machine.
• Fleet tracking: Knowing where every machine is. No more wasted trips to refuel a machine that isn’t there. No more phone calls to five different people trying to track down a machine that’s due for service.
• Uptime: Most telematics systems can track the operating hours
of a machine, and many have a maintenance tracking feature. No more missing a scheduled service and, for example, running with dirty air filters. Preventive maintenance can more easily be done regularly, on schedule, and at a time that doesn’t interfere with production.
• Cost per hour calculation: Telematics capable of tracking fuel consumption and maintenance intervals can help figure how much it costs to keep a machine productive. Armed with this information, owners can make better decisions about whether to rebuild a machine coming to the end of its life or to purchase a new one. Those investing in a new machine will have good data to decide what size, make or model to buy.
A step in the right direction
Like any information you gather about your business, telematics only provides value if you act on it. If your equipment came standard with telematics, you are already a long way toward selling more and spending less.

Do your employees have a right to work in Australia?
The TTIA’s Brian Beecroft outlines employer obligations with regard to hiring, and what could happen to those who don’t comply. Brian also has some sound advice on avoiding penalties.
ATTIA Member was recently seeking clarification about hiring a new worker and raised a question on the TTIA Industrial Hotline. The query was whether there was a specific obligation to make appropriate checks on an employee’s right to work in Australia.
The law does indeed provide a positive duty for employers to do their due diligence in that situation.
It also needs to be made clear the Fair Work Commission is on the lookout for employers who don’t comply with this obligation (so is the Australian Border Force) and, under the Migration Act, employers could be fined up to $255,000.
What to know
It’s the employer’s responsibility to check whether workers can legally work in Australia. This includes employees,
contractors, and any other workers sourced from labour-hire arrangement or recruitment agencies, and it applies to both paid and unpaid work.
Put simply, a person does not have a right to work in Australia if they are one of two things: first are those illegally staying in Australia – foreign citizens without a valid Australian visa, called ‘unlawful non-citizens’; and second are those ‘lawful non-citizens’ who have a valid visa to stay in Australia, but with work-related restrictions.
Those not well-versed in all the different types of visas and their working conditions can head over to the Australian Government’s Visa Entitlement Verification Online (VEVO) at homeaffairs. gov.au/visas. There the working conditions attached to each visa can be checked. Employers need a worker’s
permission to access their VEVO details, so make sure this permission is part of the on-boarding process.
Non-compliance penalties
Employers could face penalties for engaging a person who does not have a valid right to work in Australia.
Brian Beecroft TTIA CEO
Fines range up to $102,000 (and, for more ‘aggravated’ breaches such as forced or exploitative labour, this number can go up to $255,000).
In 2013 the law was changed to introduce stricter provisions. Employers could still face penalties even if they unknowingly employ a person without valid working rights. This new law places a positive obligation on every employer to actively make sure their employees have valid working rights. Employers who fail to comply could be liable for fines up to $76,500.
It’s also worthwhile noting even executive officers could be held personally liable if they:
• Were aware of the breach,
• Influenced the employer in the breach, or
• Failed to take reasonable steps to prevent the breach.
What to do
The last thing anyone wants is the headache of an investigation and the possibility of heavy fines hanging over a business. Under the Migration Act, employers must take ‘reasonable steps’ to check the working status of their employees and contractors. This includes keeping records of employees’ working status and making the necessary enquiries.
Don’t turn a blind eye if it’s suspected a worker doesn’t have the requisite visa status, particularly for those employing someone who has a temporary working visa. The employer has an obligation to continue to check employees’ work rights until their employment contract ends.
Proving valid work rights
To prove they have a right to work in Australia, employees can provide the following documents:
• An Australian birth certificate and a photo ID
• An Australian citizenship certificate
• An Australian passport
• A New Zealand passport
• A New Zealand birth certificate and a photo ID
• A certificate of evidence of resident status
• A valid visa with relevant work rights. To avoid penalties, it’s a good idea to be proactive about checking employees’ work rights from the very beginning. Some examples of good practice include:

• Posting job advertisements specifying applicants must have valid working rights in Australia before applying
• Introducing employee screening processes with compulsory reviews of employees’ work rights when they start work, and
• Reviewing any contracts with thirdparty labour-hire or recruitment companies to ensure they are also checking the rights of suggested workers.
For employees on temporary visas, be sure to schedule regular check-ups of their working status.
For further questions around employing (or sponsoring) visa-holders, the Department of Home Affairs has a handy resource at immi.homeaffairs.gov.au. For any questions about other obligations before taking on a new employee, a checklist is available at business.gov.au.
Employers beware
The duty of a business to check whether workers have the right to work in Australia is something that can often
be forgotten. While a person might be employed in good faith, employers are required by the law to take reasonable steps to check their working status. It’s a good idea to be proactive because, “I didn’t know,” is no longer an excuse. Investigations are a headache; fines are heavy, and the last thing anyone wants is to find out a valuable employee is employed illegally. The TTIA Legal Department can offer more clarification on this issue if needed.

Arboristry and time
In an excerpt from his upcoming book, TCAA regular Jim McArdle highlights the importance of being specific about time when it relates to arbor work.
The issue of stating time frames when securing work, specifying work when time frames aren’t given, or the relaxing of a date by which a job must be completed or dated, is important.
Recently TCAA was given permission to peer review reports from an AQF5 and saw time frames were consistently given as ’ASAP’ (as soon as possible).
The issue with allowing ASAP is it gives leeway. The client may say the work isn’t possible due to budgetary allowance or some other factor which ignores the urgency the tree’s situation.
Report time frames are a prediction by a professional practitioner and can be implanted as priorities to allow clients a better understanding of the urgency of work, or which work and at what rate it should be prioritised. The key issue is the
experience of the arborist and whether they understood the complete nature of the defect or toxicity, failure or exposure.
A useful pointer
The treatment of a toxic tree and the management of a tree with defects have similarities, but are very different. Both could be cordoned off, but with toxicity, branches, leaves, dust and even contact surfaces need to be treated or eliminated. Access should be restricted by stated time frames to allow the carrying out of those protocols. This is the case with the Dendoroncnide sp (Stinging tree or Gympie Gympie), Toxicodendron sp (Rhus tree), Nettle tree, the Euphorbaecea family and Melia species.
Other time frames can be specified
according to the nature of the exposure within one day, three days, or seven days prior to access by public or students in recreational areas.
Times for times
One useful timeframe condition which can be imposed is re-inspection after a certain, definite, period. That might be one week and three weeks after a tree has been transplanted or pruned, for instance. The clearly stated intervals indicate goals of the arborist – to distinguish moisture requirements, growth of canopy and compartmentalisation of wounds (if there are any).
Timing of pruning and maintenance can be listed as appropriate to the season: late spring, early autumn, mid-
autumn and even winter, looking for a good response after a dormant growth season.
The annual inspection has been underlined as a typical and reasonable response within educational facilities and childcare establishments, but some variation on this can be useful in high target areas bringing the timeframes in line with high occupancy. An experienced arborist can assess the environment and may suggest either monthly, bi-monthly or tri-monthly inspections be part of the essential solutions. Within these timeframes drip-feed or hand watering of plants is also suitable.
When assessing running irrigation on both large and small construction sites, water dispersion also needs to be

considered. Checking the water delivery and dispersion may be as simple as a hand or field moisture test, but the frequency of those tests is important and needs to be clearly stated in a report.
Qualifying
The TCAA typically recommends five years’ experience for an arborist to be considered a qualified, bonafide consultant.
Naturally, the candidate must be in a related field, and of course, those entering as an arborist assessor may be in a better position to qualify as a consultant more rapidly than those from horticultural gardening.
Coming through the ranks from tree worker to climber is a practical and popular way to gain experience. Not all
Level 3 arborists want to go on to Level 5, and not all Level 5 arborists want to be consultants. The question of how the arboriculture industry can capture the AQF5 consultant with experience has been an ordeal under consideration for the past 10 years. A review of the IACA and Arboriculture Australia listings show a large number of AQF5 arborists on their sites, but TCAA membership acknowledges more than 50 (that comparison includes the TCAA AQF5 arborists who own businesses but also engage AQF 5 arborists on their teams).
Peer guidance
Time frames given by consultants who are relevant and active must be related to the experience they’ve gained with like-minded arborists. Within an association it’s always the case that members are building experience through contacts at team meetings, through reference materials and from peer reviews.
With regard to a description of a tree’s condition for the next arborist reviewing a tree on a separate occasion, we should look at the condition of the tree – its vigour, vibrance and veracity –and whether the good vigour and good condition, on review, can be restated.
The given re-inspection time frame – for example, ‘in 12 months’ with a description of the tree’s condition in the assessment schedule – can assist the next assessor.
Having a picture of a usable size also is useful, particularly for monitoring trees. TCAA suggests the issue or defect should be monitored by an AQF arborist and placed with a time frame that may take into consideration weather extremes, or fall within a specific timed event, weather event, after construction, or after winds of a stated speed or force.
The TCAA’s Jim McArdle. Image: TCAA
It’s worth noting that 40kph is written in the NSW Department of Education handbook as a parameter where it considered not safe for students to be near trees.
Arborists only
Monitoring indicates an ongoing process that must be carried out by the assessor. A change can be stated by a person of locality, usually a general assistant or gardener, or even an owner can state a change, but monitoring is, by definition, to, ‘Observe and check the progress or quality of XXX over a period of time.’
A systematic review is specialist work for a qualified AQF5 arborist. Monitoring by a general assistant is not a systematic review. The AQF5 assessor should not rely on an unqualified person to determine the quality or progress of a defect.
This would be like asking a patient to prescribe medicine.
Frequency
Allowance needs to be made for material samples to be dispatched and tested, and the results and conclusion documented. The conclusion and documentation then has to be communicated to the client.
This process takes time.
Botanical identification, soil tests, aerial inspection, Resistograph and Picus tests, contaminant tests…they all take time. A business needs to allow for that interval related to the bookings and the queue of cases. It’s usually two to six weeks, but urgency can sometimes decrease time frames if there’s a hazard involved, and it’s communicated well, and the lab or business can adjust to meet the criteria.
Aerial inspections can be done more easily if the AQF5 has a climber who is mobile, and cordoning off or isolating trees is useful as a risk-reduction management process.
‘In perpetuity’ is defined as ‘for all time’ by the Merriam-Webster dictionary. As a time frame it means ‘forever’. Using this term in a report can align with a conservation process as noted biobanking-zoned areas like AIS areas of intergenerational significance. Wetlands, mangroves and waterways, foreshore zones and high-quality heritage zones would be unlikely to be challenged in a court.
It’s beyond the scope of this piece to discuss indigenous areas and scar trees, but these could be considered. The ‘in perpetuity’ comment is difficult to manage if the owner has a different intention and is under direction of a court order.

Many times over
Remedial orders in the case of Hunters Hill Council v Liu [2018] NSWLEC 108 addressed an occasion where two trees appeared to be cut down in Sydney’s Hunters Hill area and included: “No agreement on whether a period of years to monitor replacement trees should be imposed to address any arboricultural problems arising with replacement trees – monitoring of replacement trees to be required, but for a shorter period than that proposed by the council.”
The Prosecutor-proposed orders (made pursuant to s 126(2A) of the EP&A Act) to address the Prosecutor’s direction was the necessity for an ongoing regime of:
1. Arboricultural inspection of, and reporting on, the trees for a period of years into the future;
2. The furnishing to the Prosecutor of a copy of the arborist’s report after each inspection;
3. Implementation of any recommendations from the arborist arising from each inspection; and
4. The time frames within which these inspections were to be carried out.
Naming a period of time well into the future seems nebulous and not quantifiable, but furnishing a report after an inspection is. Implementation – and more importantly, the specifying of xtimeframes within which these are carried out – were a requirement. The environmental damages fine, after consideration, was $48,000.
This has also happened in critically endangered community areas related to valued vegetation time.
Tag, or you’re it
Maintenance schedules auditing insurance, workers comp or annual or six-monthly paid periods also can be cited for industry best practice.
An alternative is something dated and signed citing a certain time frame. Reports not sent within a suitable time frame can indicate duty-of-care breaches.
Arborists are almost immediately recognised and signed in when they attend a site, and these attendance logs need to be fairly accurate, both for proving compliance with a court directive and as being a professional, reliable arborist.
Finally, make allowance for gear that, by law, needs to be date stamped and in good order. Ropes are required to be tagged with dates, as are helmets, bracing equipment or rope harnesses, as is any electrical equipment.

Merlo Roto 50.26 and Advance Tree Works
While improving work capacity and efficiency is a real benefit of Merlo’s 50.26, for one Queensland-based arbor outfit, there was an even bigger consideration: safety.
Advance Tree Works is a sizable arbor company. With 12 full-time staff and plenty to keep them busy, owner Owen Hardy gave a wry grin and offered, “We’re goin’ alright.”
Asked what made up the staple of Advance Tree Work’s typical working week, Owen took a moment to sort his ideas and offered, “First of all, we’re a certified indigenous company.
“We do consultancy work – I’m a level 5 arborist and have been for six or seven years, and Advance Tree Works does everything from government, real estate, private, tree removals, tree pruning, tree assessments…basically anything and everything associated with trees.
“We also do land clearing and work for mobs like RoadTek and Queensland Rail.”
The plan
Advance Tree Works already has a fair range of machinery, including three EWPs and a few sizable chippers (and has plans to “go bigger”), an excavator and a few loaders, and about halfway through 2024 Owen added a Merlo 50.26
rotating telehandler.
“We haven’t had it long,” explained the Queenslander, “but we’ve had a bit of a play with it, and it’s definitely a game changer.
“At the moment all we’re running is the GMT050 grapple saw.
“It’s taken us a little while to get our heads around it, and it’s definitely different to some of the other gear we use. But the more we play with it, the better we’re getting.
“We’re really hoping in the future it’ll be doing side-of-road works for RoadTek, and the rail work. That’s where it’s going to excel.”
Financial sense
Committing to equipment like Merlo’s Roto 50.26 and a grapple saw is often the result of a contract or specific series of jobs, but not in this case. Owen’s motivation for the investment was far more simple and basic.
“I’m just trying to take men away from the tree,” he said with obvious sincerity. “We run EWPs and climbers, and
there’s always going to be a need for those, but when we can, we just want to try and limit having men in and around the trees, just for safety.”
Naturally a good business outcome was also part of the motivation, as Owen related.
“We see the Merlo as being versatile,” he said. “In quite a few jobs we’ve done in the past we could see where the Merlo would’ve saved us a hell of a lot of time. We wouldn’t have had to put as many men on the job, and generally, it just would have been a hell of a lot safer.”
The Merlo’s versatility is obviously a big attraction for a business like Advance Tree Works.
“I did buy a big bucket and some forks for it, but I’d probably have been better off buying the platform instead,” mused Owen. “But we will look at that down the track.”
The final word
While Owen is still firming up consistent work for the 50.26 and grapple saw, it’s gaining lots of industry interest and Owen is confident it’ll prove its worth.
“Where I think it’s really going to specialise is in storm seasons, clearing storm damage,” he prophesied with the benefit of experience.
And Owen’s horizon’s aren’t limited to Queenland’s Fraser Coast. If there’s a need for his company’s services, he’ll hit the road and go where he can do the most good.
“We travel,” he smiled. “We’ve been all over the place. We’ve been to Sydney, and recently we’ve been on the Gold Coast for a month.
“If we’d had the Merlo on the Gold Coast we’d have made a lot more money, we’d have been able to get a lot more volume done, and it would’ve been a hell of a lot safer.”

From trunk to crown
How STIHL’s battery range powers arborists every step of the way.
As arborists, every job begins at the crown and ends at the base –or sometimes, the reverse. The tools in use must align seamlessly with the workflow of climbing, cutting, and clearing. That’s where STIHL’s comprehensive battery-powered tool range excels. Designed to address every stage of tree care, STIHL provides battery solutions that are powerful, efficient, and cost-effective, offering a sustainable future for arborists.
Here’s how STIHL’s tools support arborists, from the top of the tree to the very bottom.
Crown work: precision and power above
When working at height, arborists need tools that balance reach, power, and precision.
• Pole pruning with the HTA 135: with a maximum tool length of 4.05 metres, the HTA 135 pole saw allows arborists to safely prune branches in the way of getting to the top. Its powerful cutting capability ensures precise results, making it indispensable for crown thinning and branch removal.
• Top-handle chainsaws for close work: when up in the tree, STIHL offers
two outstanding battery top-handle chainsaws: the MSA 220 TC-O – a great powerhouse with a similar power output to the well-known STIHL MS 194 T, and equipped with an integrated oil sensor, which ensures arborists can monitor oil levels mid-task, avoiding disruptions while working high above the ground; and the MSA 161 T, a lightweight saw and ideal for detailed, precision cuts. This saw offers an excellent balance of control and performance for delicate crown work. The ¼"P chain on the MSA 161 T also ensures smooth cuts to promote regrowth and remove risk of infection.
Trunk work: power meets efficiency
As arborists move down the tree, larger sections of wood demand robust, reliable power.
If the top handle saw isn’t suitable for the trunk of the tree as the work moves down, it’ll be time to call up the MSA 300 C-O – the most advanced STIHL battery chainsaw.
The MSA 300 C-O delivers 2.5 kW of mechanical power and is a great battery alternative to the petrol-powered MS 261 C-M. That makes it ideal for cutting
and removing trunk sections bit by bit.
The absence of noise, fumes, and fuel handling ensures a safer, cleaner, and more comfortable experience.
Ground work: flexibility to finish the job
At the base of the tree, STIHL continues to offer versatile solutions.
Arborists and ground crews can continue to use the MSA 300 C-O to prepare logs, or transition to STIHL’s larger petrol chainsaws for heavy-duty tasks, ensuring flexibility for any workload.
The Battery Top Handle chainsaws are also a great complement to Portable Wood Chippers, allowing removal of any protruding branches for easier feeding.
Cleanup: beyond the chainsaws
STIHL’s battery ecosystem doesn’t stop with cutting. It ensures the entire worksite is left spotless. Battery blowers quickly clear sawdust and debris, leaving the area tidy and professional, while the REA 100 PLUS Pressure Washer uses the same AP System batteries used in STIHL
AP chainsaws and pole saw, enabling tree crews to clean tools, trucks, and equipment with ease after each job when mains power isn’t available.
Lower running costs and faster ROI
Investing in STIHL’s battery tools isn’t just a smart move for the environment – it’s good for the bottom line. With no need for fuel, fewer moving parts, and lower maintenance requirements, STIHL battery tools significantly reduce longterm running costs compared to petrol alternatives.
And by cutting costs on fuel and twostroke oil while delivering exceptional durability and performance, STIHL
battery tools quickly pay for themselves. Arborists can focus on growing their business while enjoying a faster ROI.
A sustainable solution with STIHL BioPlus
STIHL doesn’t just offer a better way to work; it also provides tools to care for the planet.
BioPlus Bar & Cutter Lube is a fully biodegradable oil designed for maximum performance with all STIHL battery chainsaws and pole saws. BioPlus Bar & Cutter Lube helps arborists reduce their environmental footprint without compromising on lubrication or performance.

AirSpade
With its innovative design, powerful performance, and versatile applications, AirSpade is an ideal tool for efficient soil excavation and tree root management.
AirSpade has become a must-have tool for companies providing tree-health management and siteconstruction services. Councils and shires in Australia are increasingly specifying non-destructive digging when requesting tenders, often using AirSpade in their Tender Scope of Works.
Used correctly, the equipment is safe for both trees and personnel on site, and when paired with a standard 185cfm tow-behind air compressor, the AirSpade delivers exceptional performance for a range of applications at remote locations.
Safe for buried, solid objects
AirSpade’s proprietary supersonic nozzle turns compressed air into a high-speed, laser-like jet that dislodges soil and is one of the best ways to minimise damage to the tree’s root system during excavation. It’ll easily and gently remove soil around tree roots for better nutrient absorption and growth, and it can dig through soil, clay, and other materials with precision and control, breaking up compacted earth and improving drainage.
Powered by an air compressor, excavation with the AirSpade offers several advantages over conventional tools such as picks, shovels, and backhoes. It’s two to three times faster
than hand excavation for starters, and causes less worker fatigue. There are no sharp metal edges, so AirSpade is therefore harmless to buried, solid objects such as utility lines, telecommunication cables, hazardouswaste containers, military ordnance, and, of course tree roots.
Excavation rates
Excavation rates for the AirSpade are a function of soil type and nozzle size (air flow). Hard, stiff soils will have lower excavation rates than soft, sandy soils. For any given soil, the lower the unconfined compressive strength, the faster the digging.
As shown in the table, six standard AirSpade supersonic nozzles, ranging
in size from 25cfm to 330cfm, are available. As a rule of thumb, the quantity of soil that can be excavated in a given amount of time is rough.
Benefits
Aside from minimising damage to tree roots and underground infrastructure, AirSpade offers substantial benefits over hand and power tools for excavating around and near trees, including:
• A lightweight and ergonomic design for easy handling and reduced fatigue during extended use
• Adjustable air pressure for customised performance based on the task at hand
• A safety trigger to prevent accidental operation and ensure user protection
• Durable construction for long-lasting
AirSpade is two to three times faster than hand excavation and is harmless to buried, solid objects, including tree roots.
reliability in the very toughest and most challenging working conditions, and
• Interchangeable nozzles for versatility in various applications.
Air tilling
With proper, professional, site management, soil excavation with an AirSpade can be extremely effective and productive for the professional arboriculturalist.
Trees and shrubs suffering from shallow soil compaction – typically due to pedestrian use or vibrations caused by vehicular traffic – or lacking vigorous root growth due to poor topsoil quality, are ideal candidates for air tilling.
Since most of a tree’s roots proliferate near the surface where they have the best access to oxygen and nutrients, air tilling is excellent at promoting robust and uniform root growth. If it’s necessary to affect soil to a depth greater than 15cm-20cm, it’s possible to combine air tilling with other methods such as radial trenching or vertical mulching.
While the tree-health benefits of air tilling alone (decompaction and aeration) are significant, this proven method is often used for soil augmentation as well.
Radial trenching
Radial trenching with an AirSpade is done to modify soil composition, improve aeration, and encourage root growth to moderate depths, typically 25cm to 30cm or more, and is especially effective when trees have highly stratified or shallow depth of viable soil or anaerobic conditions.
Additionally, this application can be useful in planting areas where minimal disturbance is desired.
Vertical mulching
Vertical mulching with an AirSpade is done to de-compact and augment soil deep into the tree root zone.
This application is especially useful in areas with poor drainage, with shallow or impervious soils, or shared by perennial or ground-cover plantings where minimal disturbance is desired.
Aeration and soil amendments from vertical mulching can encourage roots to grow deep into the soil profile, improving the tree’s stability and the volume of viable growing medium.
Because vertical mulching affects the deepest soil profile, it is recommended for sites with shallow soil depth, hard-pan, anaerobic
conditions, or other types of poor growing soils and media.
Root collar excavation
Trees commonly suffer when the grade is set too high against their root flare or root collar. This can occur when trees are planted at the wrong elevation or when trees subside due to improper compaction below the root ball when they are planted. Alternatively, root collars can be buried over time due to the accumulation of mulch or soil around the tree.
Whatever the cause, harm to the tree from grade set above the root collar can be long lasting and should be remediated through root collar excavation (RCX) with an AirSpade. Symptoms of this condition include:
• Rot or infection of bark at the base of the trunk
• Growth of roots that are too high relative to the natural root flare, and
• Girdling roots, which constrict the root flare and tree trunk.
Girdling can also occur on urban sites where roots have limited room to grow or have encountered compacted or anaerobic soil conditions. Use of an AirSpade allows tree root collars and girdling roots to be excavated with minimal damage to the tree. Once uncovered, a certified arborist can
Use of an AirSpade is the best way to minimise damage to the tree’s root system.
easily identify roots that need to be removed or trained, and do it with onl;y minimal risk to the tree and root system.
Root pruning
AirSpading is safe to the tree’s roots and a highly efficient method to perform exploratory excavation to locate existing roots and utilities. Almost any site-work operations – including the building of foundations, pavements, drainage infrastructure, and utilities – present ideal opportunities for AirSpading and root pruning. Proper root pruning will encourage future growth and minimise negative impacts to structures or utilities.
Once the existing roots have been excavated, a certified arborist can easily determine the best places to make clean cuts using a hand pruner.
Bare rooting and transplanting
Bare rooting with an AirSpade can be applied to perennial, shrub, and groundcover plantings. It’s a preferred method of transplanting due to its efficiency and ability to preserve fine root systems. Furthermore, bare rooting small plants is often required during more extensive root-zone treatments such as aeration and decompaction or other site-work applications. Use of an AirSpade can significantly reduce trauma to the tree.
Urban tree soil replacement
It may be desirable to partially replace the soil around a tree’s root zone in an effort to enhance the tree’s health and lifespan.
This application is ideal for tree plantings with root zones extending underneath pavement and those that have poorly suited or limited soil volume, or where pavement is proposed to be added or replaced within an existing root zone. Similarly, this may be applied to trees planted in high-use lawn areas (for example within parks or campus landscapes,) where soil replacement is desired to improve lawn durability and health.

Ideal for small-diameter, deep excavation (potholing) where a hand shovel or backhoe bucket cannot be used.
AirVac
The next generation AirVac is the cost-effective, mobile alternative to large, expensive vacuum-excavation trucks, and an excellent companion piece for the AirSpade.
Engineered to be rugged and dependable, AirVac vacuums up to two cubic ft/min of dirt, sand, gravel, and muck. It safely uncovers underground utility lines, tree roots, or other buried facilities, and is ideal for trenching, potholing, and keyholing applications.
Soil is dislodged and driven airborne by the AirSpade, then vacuumed directly into the AirVac container. It’s ideal for small-diameter, deep excavation (potholing) where a hand shovel or backhoe bucket cannot be used. The recovered soil is easily replaced into the trench or hole.
Designed to run off a standard, 185cfm tow-behind air compressor, AirVac boasts a tank capacity of 11 cubic feet (82 gallons) and an extra-wide dump door to facilitate emptying spoils for backfilling.
The powerful, multi-stage venturi vacuum engine is also detachable to provide ease of transport. Featuring all aluminium construction with heavy-duty rear rails, loading the AirVac onto the bed of a vehicle is an easy task.
The tank lid is removable for access to the tank interior and is held in place with quick-release latches. Handles are provided on the AirVac for its lifting but are not intended to support the entire weight of the tank if full.
The AirVac has two wheels and rear handles for manual transportation. A wide dump door with quick-release latches is located at the front bottom of the tank so material can be easily removed or dumped back into the trench or hole.

A cut above
Australia has asserted its continuing dominance in a stunning fifth consecutive STIHL TIMBERSPORTS world title.
Team Australia’s ‘Chopperoos’ set back-to-back world records on the way to winning an unbelievable fifth consecutive STIHL TIMBERSPORTS® Team World Championship – and their ninth in total – in November, 2024.
The Chopperoos cemented their status as the dominant force in elite logger sports in front of a packed and passionate crowd at the Zénith Toulouse Métropole in the South of France. The USA pushed Australia all the way in the final, but was forced to settle for silver, with Canada completing the hardfought podium places.
Saw point
The Team World Championship saw 19 of the best woodchopping and sawing nations around the globe come together in front of a crowd of over 4000 fanatical
French fans. Teams battled head-tohead in a knockout format across four of the six TIMBERSPORTS disciplines: Stock Saw, Underhand Chop, Single Buck, and Standing Block Chop.
With several personal bests set during the time trial, anticipation inside the arena had built to a fever pitch with those inside the Zénith Toulouse Métropole expecting more quick times.
Nothing could have prepared them for what they witnessed, however, with Australia powering to the title by going quicker with each round, culminating in world records in both the semi finals and final.
The semi-final time of 43.64 seconds was enough to blow away the Canadian challenge – no slouches on 51.34 seconds – and lower the previous world record by almost two seconds.

Getting the chop
The Chopperoos’ seemingly flawless performance put them into a final against Team USA, with Australia incredibly going even better to break its own record and set a new worldleading time of 43.15 seconds. Team USA pushed all the way, doing all they could to clinch the crown, but were forced to settle for silver with a personal best time of 45.60.
Team Canada, vanquished by Australia in the semi final, was pitted against New Zealand in the small final, after the Kiwis were edged out of their semi final by eventual runners-up, USA. In an exceptionally close contest, the Canadians pipped New Zealand to the final podium place with a time of 48.81 seconds to 49.64 seconds.
Team Poland was the best of the rest, finishing in fifth – the highest of the European nations – after setting a personal best in a tight quarter-final defeat to Canada.
Meanwhile the host nation, France, enjoyed electric support from the partisan crowd all night, with deafening renditions of La Marseillaise and chants of “Allez les Blues” booming constantly around the arena. The French finished in a strong sixth position having beaten Belgium in an exciting round of 16 before setting a personal best in the quarter -inal defeat to the USA.
Aussie, Aussie, Aussie
Brad De Losa, of world champions Team Australia, bellowed: “We never get tired of winning, we love it. It was great to
get another win tonight, and breaking the world record on two occasions was just awesome. It’s a credit to these boys, they dig in and everyone operates really professionally. We’ve had success in the past, but everyone is still hungry and loves the winning feeling.
“The crowd here in Toulouse is one of the best we’ve ever seen. They created a really good atmosphere and it’s been awesome being here.”
Jason Lentz, of runners-up Team USA, said: “We always wish for gold, but this is a great team, a great group of guys and it’s always a pleasure to cut with them. Australia is really tough. The team is hard to beat and it’s proven by the number of times they’ve won the trophy. It’s always an honour to
come over here and compete at the highest level for STIHL TIMBERSPORTS.”
Ben Cumberland, of bronze medalists Canada, said: “That was pretty incredible, we really came together as a team over the last few days and I couldn’t ask for more from the guys than a bronze medal. We 100% won the bronze rather than missing out on gold or silver.
“The crowd here was amazing and it was a blessing to be able to compete in front of these fans here in France today.”
Following a barnstorming Team competition, the top 12 athletes in the world returned to the Zénith Toulouse Métropole to compete across all six disciplines in the Individual World Championship.
More than 4000 passionate fans filled the Zénith Toulouse Métropole for the first night of the 2024 World Championships.

Technical feature
The fine art of consulting on trees and being true to form
Cassian Humphreys underlines the importance of ethical reporting.
Using a recent arborist report of mine I am exploring the story behind the tree assessment. It was one that had me bat for the trees by putting responsibility onto the tree’s owner as opposed to those behind a possible council compliance breach.
In this article I’ll also consider confusing council specifications and definitions.
Challenges
As with carrying out contractual works on woody plants, there are many challenges with assessing and reporting on trees. One of those challenges is picking your narrative. As consultants we owe it to ourselves and the tree for our bias to be neutral. This can be difficult. In some cases the bias is the client’s objective, in others it’s about the tree, and sometimes it’s about risk. The variables change every time, but the truth doesn’t.
Sometimes the client has a bias out of sync with the tree or the situation, and that makes the need for good observation and mediation by a consulting arborist paramount.
As with all tree work, we can rarely predict how a consultation will play out. It’s the consulting arboriculturist’s job to mediate between people and trees, and this is no less true of the tree contractor. The best jobs are always those that put the tree first, and often-times in doing that the client and stakeholders are well supported too.
That was certainly true of this project.
Summary
Following a request from a Brisbane tree company, I received a commission to report on a group of trees. Seeing the scope to make an article from it and wishing to share the subject with the greater community, here it is. As a means to deliver the message and to engage with the Australian arboricultrual community I’m writing this in the same format as I do with my professional reports.
The brief was to assess a small stand of boundary trees comprised of four live and one dead specimen, located on private land in a metro suburb. The site was a multiple occupancy with a body corporate, and I was to deliver a status report on the trees following treelopping works and a possible breach in compliance. Under the Council’s Natural Assets Local Law 2003 (NALL), in the category of Waterway and Wetland Vegetation (WWV), the trees were subject to protection. My references involved a study of NALL documentation. I assessed the trees and supplied the report in November 2024.
The stand of trees are within the first third of their lifespans. For ease of reporting I address them as a stand, with reference to individual species where applicable.

The best jobs are always those that put the tree first, and often-times in doing that the client and stakeholders are well supported too “
To keep the report simple, concise and small, my discussion was necessarily included along with my observations.
Species, health, vitality, vigour and dimensions
Species: From left to right (numbers 1-5 in image 1) on site are Melaleuca spp – Black Tea Tree (1-2), Paperbark (3-4) and Corymbia torelliana –Cadaghi (5). The Black Tea tree on site is Melaleuca bracteata. The dead paperbark I could not identify, but it’s still-live neighbour Melaleuca nodosa is likely to be the same species.
Vitality: Bar the Black Tea trees (1-2), the paperbark trees’ (3-4) health or vitality is poor. T4 has died since the aerial image and council assessment was done. T5 shows signs of stress as a result of suspected excess saline water inundation from a neighbouring pool overflow. This is very likely to have killed T4.
Vigour: In this context vigour relates to genetic predisposition, both genera and all species have a moderate to strong genetic code, making the species resilient even when subject to poor vitality.
Dimensions (tree stand):
• Approximate tree stand height: 10m-16m
• Crown spread: 30m
• Diameter at breast height (DBH) of largest tree (T4) – 55cm
• Diameter above buttress (DAB) of largest tree – 60cm
Tree/site observations
The trees are situated on the western boundary of the neighbour’s property. This is a sloping block, with the slope accelerating steeply toward the western side.
My primary observation regarding the site is excessive water run-off, particularly immediately adjacent to the swimming pool located behind the neighbour. I recognised a measure of saturation from rainfall, but one of the Paperbark Gums adjacent to the area of greatest saturation and the aboveground swimming pool is now dead. The Cadaghi Gum shows signs of stress due to the same boggy anaerobic soil conditions.
Roughly half of this tree’s root system is compromised. The water in this location and running down the slope into the client’s land is indicative of pool overflow.
Considering the health impacts on the stand of trees and an adjacent revegetation planting area, the anaerobic conditions in the soil, as well as toxicity from pool salts and chlorines, is a major concern. Health limitations and constant excess soil saturation is known to impact on tree root-ball stability as well.
Tree crown structure – treelopping, council VR definitions
No obvious historical signs of impaired crown structure were observed in the trees’ crowns, bar branch-fork inclusions typical to the Melaleuca

genus. The tree-lopping works carried out by the tree contractor are possibly in breach of NALL and national/international standards for tree-pruning. As recorded by council’s aerial-mapping system, the contractor removed 50% of the trees’ volume. Sympathetic pruning carried out by a professional true to top-end international standards would have pruned less than an overall 2% to achieve crown/roof clearance.
Volume reduction (VR) as top-end works are in excess of the world’s pruning standards – of which the Australian standard falls short. However, in spite of the excessive overpruning or tree lopping for which the contractor is responsible, the impacts on the trees’ health are negligible compared to the impacts of soil water exudation caused by the overflow from the swimming pool.
Having assessed NALL documentation, I did, however, see a confusion around the definition of volume reductions. Whereas a VR as I define it relates to overall volume, this should not relate to crown height or spread. A 30% volume reduction is equivalent to a 5% height/ spread reduction over the whole of a tree. The volume is the collective amount removed by a 5% height reduction. To not specify this can only cause contractor confusion. In the compliance-notification-potential -breach NALL documentation it states ‘…in a given year 20% of a tree can be

taken’. Removal of 20% of a tree’s crown from one side will place large diameter cuts into heartwood, as with Image 5. Removal of 20% over a whole tree’s crown spread is closer to a 2.5% crown height/spread reduction with small diameter cuts kept in the sapwood. The definitions in this documentation need to reflect this.
NB: Health stress is known to impact on the biomechanical status of trees, especially tree root-plate and root-ball mechanics when associated with water inundation.
Expected future tree-health impacts
I don’t expect any further tree-health impacts if the water overflow situation is fixed. Certainly not from the tree work. Tree lopping has impacts on photosynthetic capacity and is proven to lead to side effects as is covered in the global standards, but this is driven by plant vigour and plant vitality. Knowing the tree species involved, the tree works
carried out as a one-off will have little to no impact. With reference to the health-impacts on the subject trees and the compliance notice, ref: Section 11, points ii and xi, by definition, state the residents of the neighbouring property are also potentially in breach of the tree-protection measures. Addressing this situation by plumbing the pool appropriately is essential to mitigate further tree-health impacts.
11. Pursuant to Schedule 4 of the local law, points A) and B) “interfere with”
1. (ii) to poison (including by contamination)
2. (xi) to effect any hydrological scheme which causes draining or flooding.
Conclusion
In conclusion, the stand of trees (T1-5) have recently been lopped, potentially in breach of the Australian Standard. The contractor in question possibly misled the property’s Body Corporate by stating that the works would involve targeting less than 20% of the trees’
canopies. Considering the sensitivity of relations between the neighbouring properties I am surprised council did not advise both parties to manage relations via the Queensland Civil Administrative Tribunal (QCAT). Though it is in the nature of the species of trees to outgrow the lopping works done, the trees are being impacted more by the pool overflow, which needs to be remedied for the long term. Had the parties gone through the QCAT process the right contractor capable of appropriate works would carried out the necessary pruning correctly.
The above was true to the original based on my brief report. All I omitted was client and neighbour references. The client’s bias was to avoid a fine based on non-compliance. The neighbour’s bias for notifying council, and having a potential breach imposed, was based on their position on the heavy lopping of two of their trees.
It will be interesting to learn what council decides.
