Abstract: A detection system for an agricultural header includes a belt that has at least one physical feature driven by a roller at a roller rotational speed. The detection system also includes a sensor that detects a physical feature as it passes the sensor during rotation of the belt. The detection system further includes a controller that receives a signal indicating a first pulse of a first time a physical feature passes the sensor during the rotation of the belt and a second pulse of a second time a physical feature passes the sensor during the rotation of the belt. The controller further determines a pulse frequency based on the first and second times and calculates a belt rotational speed based on the pulse frequency. The controller compares the belt rotational speed to the roller rotational speed and provides an output if the roller rotational speed exceeds a threshold.

Abstract: A sickle knife drive for an agricultural vehicle generally includes a first pump, a first motor, a second motor and a drive manifold having a plurality of connections used for connecting to other devices of the sickle knife drive and/or to devices outside of the sickle knife drive. Operation of the first pump in a forward direction causes the first motor to drive a sickle knife gearbox to cut a crop. During the forward direction, the second motor provides cooling to the fluid circuit. When the first pump direction is reversed, the agricultural vehicle supplements a fluid flow to the fluid circuit to clear any jammed crop from the sickle knives.

Abstract: An agricultural harvester includes a controller configured to receive at least one wing angle signal indicative of an angle at least one wing with respect to a center section of a header. The controller is also configured to receive a wing height position signal indicative of a distance between the at least one wing and a soil surface, determine whether the angle of the at least one wing exceeds an angle limit threshold based at least in part on the wing angle signal, and output a tilt signal to a tilt actuator in response to determining the angle of the wing exceeds the angle limit threshold. The tilt signal is indicative of instructions to maintain the distance between the at least one wing and the soil surface within a target distance threshold.

An agricultural vehicle having a header operated as described above is also provided.
