Abstract: A header floatation system that includes a header, a floatation mechanism which includes a first end and a second end opposite the first end, an adjustment array which includes at least a first contact point, a bracket which includes at least a second contact point, a skid shoe, and a fastener. The first end of the floatation mechanism can be mechanically linked to the adjustment array. Either the adjustment array or the bracket can include a third contact point. The adjustment array can be mechanically linked to the skid shoe. The fastener can be positioned adjacent to, on, or through at least the first or second contact points aligning contact between the bracket and the adjustment array.

Abstract: An agricultural vehicle including a chassis and a header carried by the chassis that includes a cutterbar assembly with a plurality of cutting units. Each of the cutting units includes a rotatable disc carrying a plurality of knives each defining at least one cutting edge and a guard assembly including a plurality of extensions. Each of the extensions includes a bottom guard portion connected to a top guard portion to define a knife slot that allows the plurality of knives to pass through during rotation of the disc. At least one rotary driver couples to the rotatable disc of at least one of the cutting units.

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: A loading assembly of a bale wagon includes a lift actuator configured to drive a clamp assembly to rotate about a local lateral axis and a rotation actuator configured to drive the clamp assembly to rotate about a vertical axis. The loading assembly also includes a controller communicatively coupled to the lift actuator and to the rotation actuator, in which the controller includes a memory and a processor. The controller is configured to selectively control the lift actuator to rotate the clamp assembly about the local lateral axis between a collection position and a longitudinal delivery position, and control the lift actuator and the rotation actuator to rotate the clamp assembly about the local lateral axis and about the vertical axis between the collection position and a lateral delivery position.

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: For a vehicle having left and right powered front wheels and a rear axle having left and right casters, with at least one of the casters being steerable, the steering angle of the steerable caster is controlled when the vehicle is stationary and executing a direction orientation maneuver prior to transitioning to a turn. The rotations of the steerable caster and at least one of the left and right wheels may be autonomously adjusted using a controller. The controller rotates the steerable caster about a caster axis in a direction consistent with the direction of the turn through a steering angle proportion to the magnitude of the turn, and rotates at least one of the left and right wheels to turn the vehicle in a direction consistent with the direction of the turn and in proportion to the magnitude of the turn.

Abstract: A screen assembly for a work vehicle is disclosed. The screen assembly may generally include a screen defining a plurality of screen openings for receiving an airflow therethrough. In addition, the screen may define a flap opening. The screen assembly may also include a flap pivotally coupled to the screen at the flap opening. The flap may be configured to be moved to a closed position when the airflow through the screen is in a first direction and to an opened position when the airflow through the screen is in a second direction.
