Abstract

There was a request to prevent a decrease in cutting performance caused by the pair of cutting blades in a chopper. [Solution] The machine is equipped with a chopper that cuts crops harvested from the field and transported toward the rear of the machine and sends them toward the rear of the machine. The chopper is equipped with a pair of chopper drums positioned vertically at different locations, and a pair of gears 46, 47 that mesh with each other to rotate the pair of chopper drums in opposite directions in synchronous motion. An elongated hole extending along the circumferential direction is formed in the upper gear 46 of the pair of gears 46, 47, or in the upper chopper drum of the pair of chopper drums, and the upper chopper drum and the upper gear 46 are connected through the elongated hole.
