The JAK-250R is an efficient and versatile tree shear model designed for use on excavators weighing 5-12 tons. The power of the JAK-250R is superior in its size class, and it is versatile for clearing small twigs and felling even larger trees. By changing the adapter to be attached to the back of the grapple, it is also possible to harness the JAK-250R for use in loaders and telehandlers.

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.

JAK-250R excavator tree shear accessories

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


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: 68 kg (150 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 grapple when rotating the grapple.


  • Rotaty manifold + mounting clip weight: 11,5 kg (25,3 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: 13 kg (28,6 lbs)


A foot is an accessory that is installed below the rear of the tree shear. The foot is used as a support point if, for example, the excavator needs to be turned to the ground by pressing the boom of the excavator


  • Weight of the foot: 10 kg (22 lbs)

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.
