Description
Equipped with the Avant adapter, the JAK-250R is an efficient tree shear designed for use in Avant loaders. By changing the adapter to be connected to the back of the grapple, JAK-250R is also possible to harness for use in other loaders and medium size excavators too.
The structure with two cylinders cuts the trees efficiently and precisely up to a thickness of 25 cm (9,8 in). The jaws and high profile of the JAK-250R tree shear take a firm and unmistakable grip on the wood. With the JAK-250R’s wide 690 mm (27 in) opening, it is also easy to cut several trees at once.
The firmly pressed wood is cut precisely and neatly thanks to a cutting blade shaped for the purpose, after which the wood material firmly attached to the grapple can be lifted to the desired location.
If necessary, the cutting blade can be removed, in which case the tree shear acts as a wood grapple.
