Abstract: A cleaning arrangement for separating a billet material from an extraneous plant matter in a sugarcane harvester includes a cleaning chamber defining an inlet for the billet material and the extraneous plant matter, a first outlet for the extraneous plant matter, and a second outlet for the billet material. A fan is positioned within the cleaning chamber and configured to generate an airflow to direct the extraneous plant matter toward the first outlet. A billet deflector is located between the inlet and the first outlet and configured to direct the billet material toward the second outlet. An actuation mechanism is coupled to the billet deflector and is controllable to adjust the position of the billet deflector. A sensor is configured to generate a signal. A controller is programmed to activate the actuation mechanism to adjust the position of the billet deflector based on the signal.
