Small forage choppers are often referred to as rakes and are mainly used to cut rice straw and wheat straw. They are also used to chop green feed. Large-scale forage choppers are commonly used in cattle farms and are mainly used to cut silage. Therefore, they are often referred to as silage choppers. Medium-sized forage choppers are generally used for both grass and alfalfa silage. The three types of choppers are used as follows: The fixed small forage chopper before work is to be fixed on the foundation or rectangular wood, and the center distance between the motor and the chopper is 1.2-1.4 meters.
