Abstract: A tractor control system, which controls an operating condition of an implement attached to the tractor. The control system includes a sensing means providing a force signal which indicates the pull force necessary to pull an implement in a desired position; a control which receives the force signal; and means for measuring at least one parameter associated with the tractor mode and/or the implement mode and the implement position is adjusted to a new position when the force signal varies. The control system includes pre-determined values associated with certain tractor and/or implement modes. A measured parameter is compared with a pre-determined parameter value and if the measured parameter would result in an undesired movement of the implement, the force signal is deactivated, or the response to the force signal is deactivated to prevent undesired movement of the attachment.

Abstract: A pipe switch having a setting system, a housing and a closure element. The housing includes an inner wall in which a feed opening and at least two discharge openings are provided. The position of the closure element is rotatably changeable relative to the discharge openings. The setting system including a control and a drive controls the closure element such that a plurality of positions of the closure element relative to the discharge openings are realized accordingly. The closure element may be in the form of a slide or a two-part element having flaps. The setting system in cooperation with the closure system provides the plurality of positions of the closure element relative to the discharge openings, in each of which the sum of the cross-sectional areas of a first and of a second discharge opening not covered by the closure element is substantially constant.

Abstract: A hitch control system for a tractor which includes a force signal, to indicate the pull force necessary for an implement attached to a hitch, and a control which receives the signal and other inputs from the operator, which indicate the required operating condition of the implement. The system adjusts the vertical position of the hitch relative to the tractor in response to variations in the force signal in order to maintain the required operating condition of the implement. The system further includes a brake sensor which provides a signal to the control which overrides the force signal so there is no movement of the hitch during braking.
