Abstract: An agricultural machine system includes: an agricultural work vehicle including a lift device; a header coupled with the lift device, the lift device configured for selectively moving the header between a plurality of positions associated with a header height including a low position, a high position, and an intermediate position therebetween such that the header occupies the intermediate position when the agricultural machine system is in a predetermined mode of operation.

Abstract: The disclosure relates to a crop merger system for a harvester. The system includes a frame, first and second rollers mounted to the frame, and a belt disposed over the first and second rollers. The system includes a motor operably coupled to and configured to rotate the second roller. The system includes a controller configured to electronically receive as input a desired speed of the belt. The system includes a sensor configured to detect a measured characteristic associated with the crop merger system, and electronically transmit the measured characteristic to the controller. The controller is configured to determine a measured speed of the belt based on the measured characteristic, and if the desired speed and the measured speed are unequal, the controller is configured to regulate the motor to adjust a speed of the belt to be substantially equal to the desired speed.

Abstract: The disclosure relates to a steering control system useful for providing stable control during high-speed operation of harvesters, such as self-propelled windrowers. The steering control system utilizes sensors for detecting a ground drive wheel speed or a swash plate position of hydraulic pumps for determining an angle of curvature used as input for controlling a steering cylinder associated with a first caster.

Abstract: The disclosure relates to a steering control system useful for providing stable control during high-speed operation of harvesters, such as self-propelled windrowers. The steering control system utilizes a sensor for detecting and regulating a position of a single steering cylinder associated with a first caster, a damper being free of sensing and providing passive damping to the second caster.

Abstract: The disclosure relates to a braking system useful for providing stable braking of harvesters, such as self-propelled windrowers. The braking system utilizes respective service brakes associated with or integrated into a front drive system of the harvester, each of the service brakes configured to slow down or stop rotation of the respective front wheels. A controller/module is configured to receive inputs and feedback parameters to actuate components of the harvester to slow down or stop the harvester.

Abstract: The disclosure relates to a ride height adjustment system useful for self-adjusting casters on suspension systems of harvesters, such as self-propelled windrowers. The suspension system utilizes sensors and hydraulic actuators operably linked to each caster, the hydraulic actuators responding to a detected ride height of the harvester to adjust the position of the casters to achieve the preferred ride height.
