Abstract
An agricultural vehicle header suspension having a frame, a plurality of supports extending forward from the frame, an anchor plate, a frame pivot joining the frame to the anchor plate to be rotatable about a frame pivot axis, a frame actuator connected between the anchor plate and the frame and configured to resiliently hold the frame at a predetermined position relative to the anchor plate, and to allow the frame to move through a range of motion relative to the anchor plate, upon compression and/or extension of the frame actuator. The frame actuator may be, for example, at least one single-acting hydraulic actuator, mechanical spring, or a pneumatic cylinder.
