ENGINE-SENSING DRAFT CONTROL SYSTEM WITH MULTIPLE FEEDBACK COMPENSATION MECHANISMS ABSTRACT OF THE DISCLOSURE An automatic feedback control system for use with an off-road vehicle having an adjustable-elevation, ground-engaging implement, such as an agricultural tractor with a three-point hitch and a plough or cultivator, is disclosed. The automatic control system provides an engine-sensing draft control system which adjusts the height or elevation of the ground-engaging implement so as to maintain the draft or load forces experienced by the vehicle at a substantially constant level. The determination of the draft being produced by the ground-engaging implement is determined by the engine speed deviation from a target point speed which is indicated by an operator-set desired no-load engine speed and an operator-set engine lug-down value or load. To provide proper operation of the engine-sensing draft control system, multiple feedback compensation mechanisms are provided, including a throttle compensation function, an electrohydraulic valve compensation function, a slip-sensing function, a sensitivity (deadband) adjustment, a maximum implement-lowering rate function, and an automatic downshift signal function to cause the transmission of the tractor to downshift to a lower speed to avoid engine stall under certain conditions.
