The design of the cutting unit uses three straight and a planetary reduction gear, respectively, through the cut a shaft, an idler shaft, cut two shafting, cut three shafting, two idler shaft, idler three shafting , compared with other similar products, using high aspect has been greatly improved. The use of planetary gear cutting head, and is directly connected with the drum, cutting unit simplifies, thus saving material and space, reducing body weight, reducing the economic costs. But also in the design process of the gears, shafts are rigorously checked to ensure that the machine is in the course of stability and security.
