An agricultural vehicle includes a chassis, a header carried by the chassis, an operator cab carried by the chassis, wheels carried by the chassis, at least one wheel driver coupled to at least one of the wheels and configured to drive the at least one coupled wheel at a wheel drive speed, a control handle placed in the operator cab that is displaceable from a zero speed position to a maximum speed position, and a controller operably coupled to the at least one wheel driver. The controller is configured to receive a header type signal indicating a header type of the header and output a resolution signal to the at least one wheel driver to define the maximum speed amount based at least partially on the received header type signal.

An agricultural vehicle configured for traveling in a driven-wheel-leading mode and a caster-wheel-leading mode. The agricultural vehicle includes a first driven wheel and a second driven wheel, a caster axle, a first caster wheel and a second caster wheel, and a steering system. The steering system includes a first steering actuator connected in between the caster axle and the first caster wheel, a first sensor connected to the caster axle, and a controller operably connected to the first steering actuator and the first sensor. The controller is configured for actuating the first steering actuator to steer the first caster wheel in the driven-wheel-leading mode and the caster-wheel-leading mode.

An agricultural baler towable by a vehicle that includes a frame and a baler hydraulic system. The baler hydraulic system includes a plurality of hydraulically operated subsystems, a plurality of hydraulic subsystem lines being fluidly connected to the plurality of hydraulically operated subsystems, and a hydraulic manifold fluidly connected to the plurality of hydraulic subsystem lines and configured for connecting to the vehicle hydraulic system. The agricultural baler also includes an electrical processing circuit operably connected to the hydraulic manifold and configured for switching the hydraulic manifold for connecting at least one hydraulic subsystem line of the plurality of hydraulic subsystem lines to the vehicle hydraulic system.

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.

An agricultural vehicle includes a chassis (), a lift arm () movably coupled to the chassis (), a lift actuator () coupled to the lift arm (), a header () coupled to the lift arm (), and a controller () operably coupled to the lift actuator (). The controller () is configured to: receive a header type signal corresponding to a header type of the header; define a lift height limit of the header based at least partially on the received header type signal, the lift height limit being a first height limit when a first header type signal is received or a second height limit when a second header type signal is received; and output a lift signal to the lift actuator () to vertically displace the header (). Header vertical displacement is limited to the first height limit if the first header type signal is received or the second height limit if the second header type signal is received.

A steering system for an agricultural vehicle that includes a steering wheel, a steering wheel sensor operably connected to the steering wheel, a drive selector having a forward position, a neutral position, and a reverse position, an actuating device configured for being operably connected to the steerable wheels of the agricultural vehicle, and an electronic control unit operably connected to the steering wheel sensor, the drive selector, and the actuating device. The electronic control unit is configured for selectively preventing a rotation of the steering wheel from steering the steerable wheels in the neutral position of the drive selector.

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.

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.

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.

The disclosure relates to a leveling system useful for self-leveling casters on suspension systems of harvesters, such as self-propelled windrowers. The suspension system utilizes position sensors and hydraulic actuators operably linked to each caster, the hydraulic actuators responding to a rotational position of the caster as detected by the respective position sensor to level the caster.
