The Biojack 400 Combi is a polyvalent felling grapple, combining knife and saw cut modes. It’s a solution for handling trees in mixed forest with different species and diameters, like on riverbanks, roadsides, or in urban area.

The knife is quick and useful for small energy wood cut, and the saw can take care of bigger trees. No more saw chain jumps with bushes.

During loading, the knife remains in the knife casing and so the grapple can be used flexibly for both cutting and loading.

The Combi is the right solution for the maintenance of mixed forests, river banks, roadsides, railways, power lines, parks, but also for thinning work, in mountainous terrain and in tree care.

The Biojack 400EG Combi features the Extra Grapple (EG-kit). This upper grapple allows holding even a larger trunk vertical, and to lower it safely onto the ground, e.g. in close proximity to buildings or power lines.

The Biojack 400 Combi is also available with accumulating grapples (E-kit), which can be used to gather several stems at a time, without having to load them, or move them onto a stack in between.

No cable, with the optional Wireless control.
