Hey all,
I have a D10 that I’ve had for around 10 years. The hydraulics always worked ok. Well they went up and down when told to and held position just fine. Traction booster never worked.
Well now the lift wants too raise any time the tractor is running. It is a series 2 with live hydraulics. The control valve feels funny now, not wanting to click into position. Also the traction booster valve that rides on the 3 point has always just been tied on to the tractor with wires. It is still hooked up to the control handle but the whole valve just goes up and down with the control handle. It does not ride on the 3 point linkage like I think it should. I don’t really know how that valve is supposed to be mounted. I don’t see a way to keep it on the 3 point linkage, but I’ve never seen another series 2 to see how it is supposed to be mounted. I don’t know if that valve is part of the problem or not.
Does the main valve give many problems? And is it rebuildable? Does it have o-rings in it that could have went bad?
Anyway the main problem is that the 3 point arms will constantly raise slowly and not go down anymore.
Anyone seen this before? Or any suggestions on what I should look for to fix this problem?
Also if anyone has a picture of how the boost valve is supposed to be attached I’d appreciate seeing how it hooks up.
Thanks for any help with this issue.

We had much the same issue with my Dad's D10. When I checked it out it was the round rod in the linkage mechanism that had slipped slightly. It has that little 'lock screw' to hold it in place. I would check that first as it may not be more serious than that.

Thanks for responding, is this lock screw in the main valve?
I will look tomorrow.
Thanks
