Rear shredder with electronically balanced "Ventilator" rotor, available with hammers (2.1 KG) or knives. Recommended for cutting grass, pruning and branches up to 8 cm of diameter. The cutting unit consists of a 6mm monolithic body built entirely in HARDOX®. 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 further retain the product inside the cutting device and then chop it further. The 4 rows of counter-knives installed inside guarantee excellent cutting quality in both 2 positions of the rear roller. Externally the side is rounded to avoid damaging the stems and vegetation of orchards and vineyards.
