Abstract
A sugarcane harvester for harvesting sugarcane including a cutter configured to cut sugarcane into a sugarcane mat. An extractor is operatively connected to the cutter, and includes a fan housing having an inlet configured to receive the sugarcane mat and an outlet configured to discharge crop debris. A fan is located in the fan housing to move the sugarcane mat through the fan housing and includes a motor, blades rotatably coupled to the motor, and a blade angle of incidence mechanism operatively connected to the blades, wherein the blade angle of incidence mechanism adjusts the angle of incidence of the blades with respect to the motor. Sensors identify an air flow through the fan housing or a load placed on the motor during movement of the sugarcane mat through the fan housing. The angle of incidence of the blades is adjusted based on one or both of the air flow through the fan housing or the load placed on the motor.
