摘要：
A combine harvester having a cleaning system with at least one cleaner assembly for cleaning the harvested and a drive assembly connected to the cleaning system to drive the cleaning system, thereby driving the at least one cleaner assembly to perform a reciprocating cleaner movement. The drive assembly comprises a variable speed drive assembly with a rotary drive comprising a rotatable output shaft for driving the cleaning system, a transmission to connect the rotatable output shaft to the at least one cleaner assembly, the transmission configured to convert an angular movement of the rotatable output shaft to the reciprocating cleaner movement, and a control unit to control an angular velocity of the rotatable output shaft based on an input signal.
