A chopper drum module and sugarcane harvester vehicle include a module frame distinct from a chassis of the sugarcane harvester having first and second drum bores on each side of the module. The first and second drum bores support, respectively, first and second chopper drums for parallel rotation. A plurality of mounting devices may be attached to the module frame or the chassis, wherein when the mounting devices are in an engaged state the module frame is secured to the chassis by the mounting devices such that the chopper drums receive sugarcane from a feed mechanism supported by the chassis. When the mounting devices are in a disengaged state, the module frame and the chopper drums may be collectively removable from the chassis and the sugarcane harvester.
