In one aspect, a method is disclosed for automatically controlling a height of an implement of an agricultural work vehicle relative to a ground surface. The method may include monitoring the height of the implement and a vehicle speed; determining an implement height error by comparing the height of the implement with a predetermined target height; and calculating a sensitivity factor based on a sensitivity setting. When the monitored vehicle speed is greater than a predetermined speed threshold, the sensitivity factor may equal a first constant sensitivity value that is proportional to the sensitivity setting. The method may include reducing the sensitivity factor to less than the first constant sensitivity value when the monitored vehicle speed becomes less than the predetermined speed threshold and adjusting the height of the implement relative to the ground surface based on the implement height error and the sensitivity factor.

An agricultural header having a frame, a first support arm, a second support arm spaced from the first support arm, a reel extending from a first reel end rotatably mounted to the first support arm to a second reel end rotatably mounted to the second support arm, a first actuator operatively connected to the frame and the first support arm and configured to move the first support arm relative to the frame, a second actuator operatively connected to the frame and the second support arm and configured to move the second support arm relative to the frame, and a control system configured to alternately operate the first actuator and the second actuator in repeating alternating incremental steps to thereby move the reel from a first reel position relative to the frame to a second reel position relative to the frame. A combine having such a header is also provided.

A device for cutting vegetation comprises a base capable of being selectively propelled about a surface upon which the device sits, a turret affixed to the base and rotatable relative to the base, and one or more vegetation cutting tools affixed to the turret. The turret and cutting tools rotate together 360 degrees relative to the base as the base moves about the surface such that the cutting tools are adapted to cut vegetation on the surface.

An implement includes a hydraulic control to move rear wheels upward and downward. A hitch frame has a rear end pivotally connected to a front of the implement's frame about an upper hitch pivot axis and a front end connectable to a tractor drawbar. A tension link has a rear end pivotally connected to the front end of the implement about a lower hitch pivot axis located below and parallel to the upper hitch pivot, and a front end movably mounted to a front of the hitch frame. A front hydraulic cylinder moves the front end of the tension link forward and rearward. The hydraulic control activates the front hydraulic cylinder to move the tension link rearward as the rear hydraulic cylinder moves the rear wheels upward with respect to the implement frame, and to move the front end of the tension link forward as the rear wheels move downward.
