The present disclosure discloses a chopper mechanism (10) for chopping stalk-like plant wherein the chopper mechanism (10) includes a plurality of chopping elements (20) are removably mounted on the a pair of chopper drums (12a, 12b) via associated holders (16). The chopping elements (20) are mounted on the chopper drums (12a, 12b) in a circumferentially spaced apart and defining a predetermined radial angle (a) therebetween. Each of the chopping element (20) having a pair of substantially parallel cutting edge (22a, 22b) spaced apart by substantially parallel mounting surfaces (24a, 24b). One of said cutting edge (22a or 22b) is selectively engaged in the chopping while the other cutting edge (22b or 22a) is enclosed within the holder (16). The parallel cutting edge (22a, 22b) of the chopping elements (20) facilitate in reversing each chopping elements (20) depending on the degree of abrasion of the cutting edge (22a, 22b). |
