ABSTRACT:
A base cutter assembly (16) of a sugarcane harvester (10) in which the accumulation of trash around the drive shaft (32) of the base cutter assembly (16) is prevented. The base cutter assembly (16) is provided with a shaped drive shaft (32) which causes the trash which in use is wrapped around the shaft, to migrate towards an intermediate portion (40) of the drive shaft (32); and a cleaning means (34) positioned adjacent the intermediate portion (40) and adapted to remove the trash which builds up at the intermediate portion (40). The cleaning means may be in the form of a rotatable wheel (42) which is angled with respect to the longitudinal axis of the drive shaft (32).
