Abstract
A harvesting assembly is provided with a transverse feed auger for directing harvested crop material into a feederhouse. The feed auger is also provided with retractable fingers. The retractable fingers are freely rotatably mounted on a finger timing shaft located in the feed auger. A feed auger torque sensor is mounted to the feed auger and communicates an actual feed auger torque signal to a controller. The controller is provided with a memory having a maximum desired feed auger torque signal. When the actual feed auger torque signal exceeds the maximum desired feed auger torque signal, the feed auger drive is disengaged. A timing shaft torque sensor is mounted to the finger timing shaft and communicates an actual timing shaft torque signal to the controller. The memory of the controller is provided with a maximum desired timing shaft torque signal. When the actual timing shaft torque signal exceeds the maximum desired timing shaft torque signal a brake is applied to the feed auger.
