Abstract
A chopper mechanism for chopping stalk-like plant wherein the chopper mechanism includes a plurality of chopping elements that are removably mounted on the pair of chopper drums via associated holders. The chopping elements are mounted on the chopper drums circumferentially spaced apart and define a predetermined radial angle (α) therebetween. Each of the chopping elements having a pair of substantially parallel cutting edges spaced apart by substantially parallel mounting surfaces. One of the cutting edges is selectively engaged in the chopping while the other cutting edge is enclosed within the holder. The parallel cutting edge of the chopping elements facilitates in reversing each chopping element depending on the degree of abrasion of the cutting edge.
