I could use some thoughts from anyone. When I hook up equipment to my auxiliary connector on the rear, there is pressure on the hose but no lifting. Could this just be the wrong ram, on the mower, for the 45 system? Have tried different settings on the pump but no change. Any thoughts?

Are the cylinders on the equipment you are hooking to set up for single action or double action? Are there 1 or 2 hoses on the cylinder? The WD was designed to run single acting cylinders (one hose). If the cylinder has 2 hoses on it, remove the hose that is not being used and put a cylinder exhaust port in.

Coupler bad if it has pressure on hose before coupler. If pressure after couppler, the hose could be plugged. MACK

Your tractors lift arms should go up and down as you raise and lower the hydraulic lever. If they work, you must have bad or mis-matched coupler parts. If the lift arms don't do anything, you have hydraulic pump problems.
