JAK-300R for wheel loaders and telehandlers description

The JAK-300R is designed for use with 6 to 21-ton kg (13227-46297 lbs) wheel loaders and telehandlers with a maximum lifting capacity of at least 1300 kg (2866 lbs) or more at their maximum reach. By changing the rear part to be connected to the grapple, it is also possible to harness the JAK-300R for use in excavators, 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.

JAK-300R tree shear accessories

The use of the tree shear can be diversified by equipping it with the following accessories:

JAK-350R Guillotine Unit

Guillotine unit streamlines the operation of the tree shear and makes wood handling even more accurate, versatile and safer. The JAK-350R Guillotine Unit cuts wood neatly and effortlessly up to a width of 350 mm.

The location of the cutting blades far from the jaws allows the tree shear to be used simultaneously for cutting, loading and all wood handling. When using the JAK-350R Guillotine Unit, the jaws of the tree shear always close first and the cutting blades close only after that to cut the wood.

The high design of the JAK Tree Shear, combined with the two-stage cutting function, ensures that even a thick tree trunk stays in the firm grip on the jaws after cutting. Separately closing blades also make it easier to clean small and bendy twigs.


The rotator improves the use and reach of the grapple, making wood handling easier. The rotator works, as its name implies, to allow the tree shear to rotate along the axis of the arm. This allows for a wide variety of working angles and makes clearing easier, especially when working in challenging terrain.


  • Weight of the rotator: 139 kg (306 lbs)
  • Rotator mounting clip weight: 5 kg (11 lbs)

Rotary manifold

The rotary manifold to be installed in connection with the rotator allows the grapple to be rotated indefinitely in both directions. When the hydraulics associated with the use of the grapple jaws are controlled through the bushing, the user does not have to worry about the hydraulic hoses rotating inside the tree shear when rotating the grapple.


  • Rotary manifold + mounting clip weight: 11,5 kg (26,4 lbs)


Collector optimizes work efficiency and saves time. If the purpose of the tree shear is to clear smaller and more densely growing timber from the same area, this process can be made much more efficient and faster thanks to this collector.

The collector makes clearing easy and fast as the same area can be handled with less effort. With the help of a collector, the tree shear can collect several trees growing separately in the same bundle.

Felling support

Felling support attached to the tree shear makes wood control easier and safer. Optional felling support raises the height of the tree shear impact plate to ensure firm control of the wood. In this way, the felling support ensures solid control of the wood.


  • Weight of the felling support: 33 kg (72,7 lbs)


The saw brings efficiency to clearing work. With the help of a saw mounted on the place of the cutting blade, you can neatly cut even several trees at once in no time. The saw also allows more thicker trees to be cut, which not be possible with a standard cutting blade alone.


  • Saw adapter weight: 120 Kg (264 lbs)
  • Saw unit weight:  102 kg (225 lbs)
  • Minimum oil pressure for saw: 160 bar (2320 psi)
  • Minimum oil flow for saw: 65 l/min (17.1 gal/min)

Quick valve

Quick valve improves the working speed of the tree shear. It allows faster movement of the unloaded gripping phase. The operation of the Quick valve is based on changing the oil flow when rapid traverse is more important than maximum force.
