A grounds maintenance vehicle having a vehicle frame is disclosed. An implement is coupled to the vehicle frame and has a first implement end and a second implement end. A height selection tool is configured to select one vertical position of a plurality of selectable vertical positions, where each vertical position limits a distance between the implement and the vehicle frame. An implement angle selection tool is configured to change the elevation of the first implement end relative to the second implement end and fix the elevation of the first implement end relative the second implement end. The implement angle selection tool has a manually engageable mechanism configured to change the elevation of the first implement end relative to the second implement end when the implement angle selection tool is disengaged.

A ground contour sensing system and method for a vehicle with a mowing head. The system includes a sensor system that measures a ground contour in front of the mowing head, and generates contour measurement signals; and a controller that determines whether to move the mowing head based on the contour measurement signals, and generates movement commands for the mowing head when it determines to move the mowing head. The mowing head can include tilt and lift cylinders, and the controller can determine whether to move the mowing head using the tilt or lift cylinders. The sensor system can include a pivot arm that moves in response to changes in the ground contour, and an angle sensor that measures an angle of the pivot arm. There can be one or more sensor systems positioned between the right and left sides of the mowing head.

A boom mower attachment that moves a cutting mechanism in a first movement, a second movement, and a third movement by only using two motions of a single control and method of use thereof is provided. The boom mower may include a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. An implement control system including a control, at least one function switching mechanism, and an implement is also provided. Activation of the control is operative to move the implement in a first mode, a second mode, and a third mode by only using two motions of the control.

An agricultural vehicle includes a chassis and a header carried by the chassis. The header includes: a header frame; a cutter movably coupled to the header frame; a reel arm pivotably coupled to the header frame; a reel carried by the reel arm and including a plurality of tines; a variable displacement fluid cylinder including an interior chamber, a first piston linked to the reel arm placed within the interior chamber and a second piston placed within the interior chamber, the interior chamber defining a shared volume between the first piston and the second piston; and a piston driver linked to the cutter and configured to translate movement of the cutter relative to the header frame into displacement of the second piston within the interior chamber.

A header has a cutterbar table that is movably mounted to a frame and configured to cut a standing crop, an intake auger mounted to the frame and configured to receive the cut crop; the intake auger further being configured to rotate, during a normal state, in a predetermined direction, and to rotate, during a corrective state, in a predetermined reversed direction, an actuator assembly configured to displace the cutterbar table relative to the frame, thereby changing a distance between the cutterbar table and the intake auger, a control unit configured to, upon receipt of an error signal indicative of a need to operate in the corrective state control the actuator assembly to displace the cutterbar table away from the intake auger to a safe operating position, prior to controlling the intake auger to rotate in the predetermined reversed direction.
