Additional work for excavators with the JAK tree shear | Experiences of the JAK-300
Lauri Leppänen of LL-Konetyö, a civil engineering, and forestry company, has been satisfied with the acquisition of the JAK tree shear. Tree shear gives the entrepreneur more versatile opportunities to earn additional income, especially during the wintertime.
Excavators are easily left for less use in the winter when the ground is frozen and it may not be sensible to do excavation work. However, collecting energy wood is also possible easily during the winter. The tree is lightweight and the abundant foliage does not interfere with visibility. The snow-white ground also helps to distinguish trees from the background and other vegetation.
The company’s basic machine is an 18-ton kg (39683 lbs) tracked Hitachi excavator equipped with a rotator, which Leppänen aims to keep in constant use throughout the year. For this type of machine, Leppänen has also acquired a JAK-300 tree shear, which succeeds in felling even larger wood.
Versatile energy wood harvesting
LL-Konetyö mainly harvests energy wood from field sides and roadsides, as well as from young forest rehabilitation sites. In the end, wood harvested with a tree shear ends up as raw material for domestic thermal energy. The company’s operations are located in the city of Joutsa in central Finland, where there are lots of smaller trees to be harvested for energy wood.
For young forest rehabilitations with lots of small-diameter trunks, a mass handling Collector is an absolute accessory. Collector makes operations significantly more efficient, as it allows the shear to collect up to a dozen smaller trees at the same time. When the tree shear is full, the trees can be conveniently lifted in one motion along the run. This makes work comfortable and, of course, more productive.
Occasionally, even larger trees may be felled. However, the Jak tree shear also fells even log-sized trees in a controlled manner. For example, at the edge of power lines, trees dare to be safely removed when the tree to be felled remains well upright under the tight grip of the shear.
The cutting blade has also been a positive surprise. A new spare blade for the tree shear can also be found, but it has not had to be put into service when the original blade is still in full swing. It has withstood occasional hits in rocks as well, and it has required nothing more than the occasional kiss of a grinding wheel to sharpen it. Leppänen adds that he also uses the shear without the blade for lifting stones or poles, for example.
“I must say that I am satisfied with my purchase” – Leppänen concludes. You can follow the company’s activities on LL-Konetyö’s Facebook page
