FORESTCUTTER

Fastest machine on the market, can also be used as a sorting grapple* One machine, three functions, clearing bushes and trees, and maintaining wooded areas The fine cut allows trees to regrow again optimally More view of your work, and higher capacity. With the optional swivel head, you can cut through both thick branches and thin trees cleanly whilst the crane is swivelling Trees are cut at ground level, reducing the risk of tyre damage Significantly longer service life for the chisels compared to the chain. The chisels can also be rotated multiple times More stable operation, vandal-proof thanks to robust cutting technology (no flying chain) Strong gripping force, both 4-finger gripper and collection arm Versatile application Up to three times faster operation compared to shears

Hammer function + 1x double acting + leak hose
