PROPERTIES AND DURABILITY ARE A CLASS OF THEIR OWN
What makes the Bison 300 PRO wood grapple special?
The toothed grapples with additional reinforcements ensure a stable and strong grip, which in turn speeds up the work process.
The cross-cut support ensures a precise and clean cut on the narrower grip and prevents roots and stumps from getting into the stored bush.
The reinforced container/cylinder guard ensures extremely precise synchronous movement of the grapples and protects the cylinder from possible damage.
The replaceable blade is made of wear-resistant HARDOX steel.The blade attachments are surrounded by special inserts that protect them from possible deformations. Due to this, the blade is very easy to change even after a long service life.
The purpose of the cutting blade is to speed up the cutting process because the trees are cut on two sides at the same time. Significantly reduces the force required for cutting.
The bolted joints are protected by special inserts, which prevent wear or deformation of the fasteners.
The stump uprooter is one of the useful accessories of the BISON 300, which helps to get rid of cumbersome stumps during cutting without changing the device.
Durable housing molded into a single piece of high-quality spring steel.
Additional collector is an accessory device, which is attached to the main device with a bolt connection. An additional collector allows you to hold a larger amount of brush without the need for a storage procedure in the meantime. This saves time and reduces equipment wear. The additional collector is also suitable for other manufacturers' devices.
Fastening of customer's choice.
Available with short and long shaft.
