JAK-400S Excavator Grapple Saw – 400mm Cutting Capacity

Powerful tree cutting. Simple hydraulics. Complete control.

The JAK-400S Grapple Saw is a versatile excavator tree cutting attachment designed for safe, efficient tree felling, pruning and timber handling. Built in Finland for 8–12 tonne excavators, it combines a powerful hydraulic chainsaw, 360° rotation and a secure grapple design, with an impressive 400mm maximum cutting diameter.

What really sets the JAK-400S apart is its remarkably simple hydraulic setup. Thanks to an innovative electro-hydraulic control system, all grapple, saw and rotation functions operate through just one double-acting hydraulic circuit – requiring only one hydraulic supply and one return. This simplifies installation and operation, without the need for multiple auxiliary hydraulic circuits.
