An auger slip can be monitored to determine when an auger slip condition indicative of possible plugging of a harvesting work vehicle is present. In response to the auger slip condition, various implements of the harvesting work vehicle can be adjusted to resolve the auger slip condition or mitigate plugging. The implements may include a cutter bar, an auger, a roll gap, a swath flap, and/or a shield former. Further, an engine speed or vehicle speed of the harvesting work vehicle can be adjusted to mitigate plugging.

A windrower implement includes an actuation system coupled to a rotating element of a crop conditioning system for controlling a position of the rotating element to define a processing gap. A first hydraulic motor is coupled to the rotating element. A merger attachment includes a driven roller rotatably supporting a conveyor. A second hydraulic motor is coupled to the driven roller. A controller is configured to determine a current value of a first fluid pressure of the first hydraulic motor and a current value of a second fluid pressure of the second hydraulic motor, and compare the respective fluid pressures to respective thresholds. When the current value of the either the first or second fluid pressure is greater than their respective threshold, the controller controls the actuation system to increase the processing gap to prevent plugging of the crop conditioning system.

Systems and methods are provided for monitoring and controlling operation a conditioning system of or otherwise associated with an agricultural machine, which may include a mower conditioner. Sensor data indicative of a real-time displacement associated with component(s) of the conditioning system is used to determine a measured displacement, which is compared with a minimum displacement for the component(s). The comparison is used to control an operational parameter of one or more components associated with the conditioning system. The controllable component(s) can include the conditioning component(s), and the one or more controllers may be used to control the operational parameter (e.g. operational speed, position, etc.) of the conditioning components and ultimately a level of conditioning applied to cut crop material passing through the conditioning system.

An agricultural crop conditioner comprising: a frame with a first conditioner roll rotatably mounted to the frame, and a second conditioner roll rotatably and movably mounted to the frame. A tensioner is connected between the frame and the second roll, and configured to generate a first force to bias the second roll towards the first roll. The conditioner has a roll drive circuit comprising a hydraulic pump configured to drive a hydraulic motor. A hydraulic actuator is operatively connected to a forward supply line between the pump and the motor. The hydraulic actuator is configured to change the first force as an inverse function of changes in a pressure of hydraulic fluid in the forward supply line during operation of the hydraulic motor in a forward processing direction.

An agricultural crop conditioner comprising: a frame; first and second conditioner rolls with the second conditioner roll being movable towards and away from the first conditioner roll to change a size of a gap between the rolls; a tensioner configured to generate closing force component to bias the second conditioner roll in the closing direction; a conditioner roll drive circuit; and a hydraulic actuator. The conditioner roll drive circuit has a hydraulic pump and motor to drive at least one of the conditioner rolls. The hydraulic actuator is configured to convert pressure from hydraulic fluid in the reverse supply line into an opening force to bias the second conditioner roll away from the first conditioner roll. The opening force is less than the closing force when the pump is operated in a forward direction, and greater than the closing force when the pump is operated in a reverse direction.
