Finland is one of the few places in the world that has so far kept a lid on the coronavirus pandemic. So despite some early uncertainty, the 2020 running of the bi-annual FinnMetko forestry show went ahead as planned, albeit later in the year (September 3rd to 5th) and with fewer exhibitors than normal. Held in the town of Jämsä, the event showcases the latest innovations in forestry equipment and, despite its reduced scale this time round, almost 10,000 visitors attended the show in 2020.
COMPACT HARVESTING SOLUTIONS
USEWOOD Already known for its compact clearing machines, harvesters and forwarders, Muurame-based Usewood presented the Combi Master, powered by a four-cylinder Kubota engine delivering 33kW. The machine resembles the company’s forwarder offering, but has a retractable rear chassis to shorten the overall length of the machine while in harvester mode. This has benefits when working within the stand off thinned racks or when using the machine to conduct clearing operations. Despite this compact form, when extended to use in forwarder mode the machine has no difficulty accepting log lengths up to 4m without the need for additional bunk extension structures.
Usewood presented the machine with its own in-house produced UW180S harvesting head, which has the ability to fell trees to a maximum felling diameter of 22cm. The head is fitted with a roller feed mechanism executed by two feed rollers, and the delimbing function is fulfilled by two upper moveable delimbing knives together with a top fixed knife.
COMPACT FORWARDER OFFERINGS
ALSTOR Compact forwarders were popular at FinnMetko, with the Swedish-built Alstor 8x8 taking pride of place alongside machines from Kranman, Kinetic and Logbullet. Interestingly, all the machines have been engineered by people with firsthand knowledge of timber harvesting, with designs based on their own needs.
KINETIC The Kinetic mini forwarder in eight-wheel configuration is another contender in the compact forwarder market. The 8x8 machine weighs 1,790kg and has a load capacity of 3 tonnes. Power is provided by a Yanmar engine with crane reach extending to 4.7m.
LOGBULLET Logbullet completed the compact forwarder line up with its eightwheeled hydrostatic drive unit, which was developed by Pekka Syvanen for his own timber extraction interests. The machine weighs a mere 1.7 tonnes and measures just 5m long and 1.5m wide. Ground clearance is a generous 40cm and power comes from an 18kW Kubota engine. Equipped with a Farma C3.80 crane, which offers a maximum outreach of 3.8m, the machine has a galvanised bunk structure for extended working life.
LARGER HARVESTER DEVELOPMENTS
Larger forest machines also cried grabbed the attention of prospective end users at FinnMetko 2020, the most notable being from Finnish manufacturers Nisula and ProSilva. Such is the level of success both companies are experiencing, they have greatly increased their product ranges in
NISULA
recent years with the trend continuing through 2020 and beyond with a number of new product introductions.
NISULA Nisula’s excavator-based harvesters offer an oscillating undercarriage conversion coupled with the option of an additional telescopic boom extension with heel boom feature, which not only extends the working range of the machine when using its harvesting head but when required also provides a degree of climbing assistance when faced with steeper terrain. Excavatorbased harvesters showcased at the event included a Volvo ECR145LC and the more compact ECR88D Pro demonstrating the different size class conversions that can be facilitated.
Purpose-built wheeled harvester bases were also presented by Nisula. The N5 thinning machine is based on a Lannen backhoe loader and is now also available as a six-wheeler alongside the more traditional four-wheel format. Nisula’s new flagship harvesting head, the 1,420kg 755X was also displayed. Intended for tracked excavator bases from 16 to 23 tonnes, it employs three feed rollers driven by four powerful feed motors, with
delimbing conducted by one fixed top knife and four movable knives offering thorough stem contact and positive gripping characteristics. Its powerful Parker saw motor enables a cutting diameter of 75cm.
PROSILVA With harvesting base machines offered in four- and six-wheeled configurations, ProSilva also offers steel, quad track drive based units which have been proven on its original C6 harvester for many years. However, ProSilva has now introduced a smaller unit in the form of C3, offered in either four- or six-wheeled formats. Launched during April 2020, the machine can be adapted to incorporate a wide choice of cranes and harvesting heads (Logmer 13105H crane and Waratah H413 harvesting head pictured left).
RISUTEC Risutec attracted much attention with its live mechanised planting demonstrations utilising a Doosan DX160LC-3 excavator equipped with its PM160 tree planter. However, the company was eager to promote other products, including the original clearing head line up, which was the basis for its establishment. An example of the latest clearing head was mounted on a Doosan DX62R-3 reduced swing radius excavator, while examples of Risutec’s new tree shear attachments were presented for the first time at FinnMetko.
Designated M50EX, the tree shear offers a number of Risutec-specific design features, which serve to provide a firm grip and positive cutting action through the use of twin blades that close on the stem from each side as opposed to the more common single-knife approach.
