Rear , front or reversible shredder with electronically balanced "Ventilator" rotor, available with hammers or knives. Recommended for cutting grass, pruning and branches up to 8 cm of diameter. The cutting equipment consists of a double internal frame built entirely in HARDOX® (wear-resistant and anti-abrasive steel). Double position of the back support roller: 1) self-cleaning to allow the shredded product to be unloaded behind the roller. The power absorption of the tractor is thus reduced to a minimum with consequent reduction in consumption. 2) rear, to further retain the product inside the cutting device and then chop it further. The 3 rows of counter-knives installed inside guarantee excellent cutting quality in both 2 positions of the rear roller
