I recently purchased a 1986 CaseIH 244. It is a Mitsubishi tractor that International and then CaseIH sold in the mid 80's. It apparently is the equivalent of a Mitsubishi MT210. It has a Mitsubishi K3D 3 cylinder diesel w/live hydraulics, power steering, and 3 speed transmission w/3 speed rear differential. It has Cat1 3 point with draft control. A KMW model 95 loader is mounted and receives its hydraulics from two ports located at the left rear of the tractor. The problem I am having is the 3 point will not lift my 5 ft Howse disk. The disk weighs approximately 500 lbs and should not be an issue. I also noticed the 3 point arms do not raise very high. I believe I have a way to fix the arm height issue through an adjustment of the nut on the hitch raise control rod. I was trying to move the disk using the 3 point when I discovered the tractor would not lift it. I never connected the top link, because the top link fully compressed was too long to be connected. After hooking up the two lower hitch pins I attempted to raise the front of the disk so I could attach the top link. The 3 point arms did not move. I unhooked the lower pins and moved the tractor forward, then stood on both lift arms and raised the 3 point. It lifted my weight (250 lbs). I ended up moving the disk by using the loader to pick the disk up using a log chain. The loader had no problem picking the disk up, so system hydraulic pressure and volume are not a problem. The service manual talks about a hydraulic relief valve located on the left side of the hydraulic hitch cover. You adjust the shims to change the opening pressure of the relief valve. My question is: Does this relief valve only affect the 3 point or the whole hydraulic system? The manual is not clear. It would seem I have enough system pressure, just not at the 3 point. Any advice would be appreciated.
