Biojack 400S is made of heavy-duty and high-quality raw materials, giving the units a sturdy and durable structure. Biojack 400S is suited for first thinning, energy wood harvesting and for infrastructure construction.

Trunks are cut with a chainsaw. There are two blade alternatives available: a regular direct blade and a fish-type blade, which is also well suited for cutting brushwood.

Biojack guillotine can be used flexibly for cutting and loading; no conversions are required. During the loading operation the blade stays in its case and, if necessary, can be activated by pushing the button. An agricultural tractor, an excavator, a skidder, a harvester or a lorry can be used as the base machine.
