Description

Equipped with the excavator adapter, the JAK-300R is a powerful tree shear designed for use in larger size excavators weighing over 12 tons (26455 lbs). By changing the adapter to be connected to the grapple, JAK-300R is also possible to harness for use in loaders and telehandlers, for example.

The jaws of the JAK-300R take an unfailing grip on the wood. With the wide opening of the grapple, several trees can also be cut at once, and the force of the grapple does not coagulate even with a large mass. Due to its large size, the JAK-300R easily cuts a tree’s diameter up to 30cm (11,8 in) thick. At the same time, it is also ideal for felling into smaller stands, as its handling is precise and effortless.

The wood that has been firmly pressed by the grapple is neatly cut thanks to the grapple cutting blade. If necessary, the cutting blade located below the JAK-300R can also be removed, in which case the energy grapple acts as a normal wood grapple.
