Abstract
A chopper system for a sugarcane harvester comprises a chopper and a timing-adjustment tool. The chopper comprises a first chopper drum mounted for rotation about a first axis of rotation and comprising blades, a second chopper drum mounted for rotation about a second axis of rotation and comprising blades that cooperate with the blades of the first chopper drum to sever sugarcane stalks into billets upon rotation of the first and second chopper drums respectively about the first and second axes of rotation, and a gearbox that coordinates rotation of the first and second chopper drums relative to one another to establish a timing of operation between the blades of the first and second chopper drums. The timing-adjustment tool removably mounts to the chopper to adjust the timing of operation.
