Rear shredder with electronically balanced "Ventilator" rotor , available with hammers or knives. Recommended for the shredding of grass, pruning and twigs up to 5 cm of diameter. The chopping equipment consists of a double internal frame built entirely in HARDOX® (wear-resistant and anti-abrasive steel). Double position of the rear 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 retain the product more inside the carving and then chop it further. The 2 rows of counter-knives installed inside guarantee excellent cutting quality in both 2 positions of the roller.
