The TH and TS series, are equipped with large diameter and thickness rotors with interchangeable hammers or blades. They rotate at high speed by cutting the grass at the same time it is mulched into the cavity of the machine, leaving the remains to the outside through the back and depositing uniformly on the ground without creating cords. The degree of cut is so high that the size of the remains is almost negligible. Bottlenecks or congestions never appear in the rear roller, since the material passes over it, which increases considerably the high quality of finish.
