Hi there,My 3-point is acting up and I was wondering about the steps to take in trouble shooting it. The symptoms are The unit will lift and lower using the draft contorl with the position control in the up position. The unit does not have enough lifting power to lift my son, 95 lbs on a rear fork unit. the position control arm will not move the 3-point with the draft in either up or down position. The lift pulses gently when lifting the arms with a very light load on them. There does not seem to be a difference whether cold or warm. The tractor is a 1974 MF40 industrial. The tractor had some water in the transmission / hydraulic oil when I got it. I drained and replaced the oil. Should I 1. Replace the filter on the pump unit.
2. Find out that I am using the controls in a wrong manner. (I spent hundreds of hours on MF65"s and a 285 back in my youth. ((1968 to 1976)) however, with my old age (51 approaching) I could be forgetting something.)
3. I did look at the owners manual, and think that I am trying to use the tractor correctly.
4. Should I check out the pressure relief valve. It could be loosing the required pressure. Anyway, I would appreciate any information that anyone wants to give me. V/R
