A load sensing and lift cylinder adjusting system for a three-point linkage arrangement on a tractor, which includes; a control system and load setting system; a load sensing system in the form of a load sensing proportional valve in fluid connection with the lift cylinder; a load adjusting system which includes a load sense pump connected to the load sensing proportional valve and the tractor's hydraulic oil supply; the load sensing system monitors load on the lift cylinder via oil pressure from within the lift cylinder and if the load drops from the pre-set load this sends a signal to the load adjusting system which diverts oil from a hydraulic oil supply to the lift cylinder to maintain the pre-set load; if the pre-set load is exceeded a signal is sent to the load adjusting system which diverts oil from the lift cylinder back to the tractor's hydraulic oil supply.
