Last year I bought a 1977 B7100. My first tractor. I took it to my local tractor mechanic recently to have him go through it and check it out. The hydraulics weren’t working well. There wasn’t much lifting power with the 3 point hitch. The mechanic said that there was a lot of water in the system. The shifter boot had cracked and the previous owner left it outside. He drained and refilled it and the 3 point hitch is much stronger. It goes up with lots of weight on it but it won’t go down. I can get it to drop by shutting off the tractor and putting the 3 point hitch lever (by the seat) in the up position. The 3PT will drop slightly, 1/2 inch maybe. By wiggling it back and forth I can get the 3PT to drop. With the engine on pushing the 3PT lever forward (which should drop the 3PT) does nothing. I spoke with my mechanic and he thought I should run it a bit and see if it sorts itself out. I’ve mowed with it for several hours. It hasn’t change. I'm thinking (guessing/hoping) there is some sort of relief valve that is stuck closed? Maybe? Any thoughts?
