Hi Kevin, the 574 has an open center hydraulic system, meaning there should be no load on the hydraulic pump when all control valves are not being used. For the 3pt circuit the high pressure oil should come out the bottom right port on the MCV valve flow up under the seat to draft control then unto remote control valves and return via draft control to second port from bottom on right side of MCV valve to be filtered before entering the pump again.
If the tractor engine is being loaded by the hydraulic pump when no hydraulic control valve is being used then there is a problem somewhere.
