Mike: The most likely cause of your problem is sticking control valves inside of the pump. If your lift arms bleed down overnight and as soon as you start the tractor they go up, then this is your problem. If they don't go up when you start the tractor until you move the control lever up to raise, then you have a problem in the hold position valve on top of the pump. If the control valves are sticking, you can usually get them to free up by turning in the screw on the front of the pump by the bell housing with the large knurled head. If this doesn't work, then you will have to remove the pump to take it apart and clean and free up the control valves. If the hold position valve is the problem, then first check to see if the rod that operates the valve is attached at both ends and working the valve. If the rod is working the valve, then you will have to remove the valve and take it apart to check for any defective parts. I hope that this information is a help to you. Have a good day. Gordon

I had also considered buying a landrover and trailer, but the price of a ... [Read Article]
