A hydraulic implement system (100, 200) is provided that allows a load-sense power source (124, 224) to be activated and deactivated depending on a SCV (126, 226) function. The load sense power source (124, 224) is activated when wing cylinder structures (104, 204) are fully extended to maintain proper down force on the wings. It remains activated or latched when the SCV (126, 226) is returned to neutral. It is deactivated or unlatched when the wing cylinder structures (104, 204) are retracted. Two circuits have been devised to accomplish this latching function. Both of these latching circuits can be used with a sequencing circuit.
