3-Point Hitch 3 point hitch jumping

[charlton289]

I have a 55 ferguson to 35 and just rebuilt engine. Tractor sat for about 2 years but the 3 point lift keeps jumping when under low lift pressure. Like bush hogging and grader blade. Is there anything I can do to keep it from jumping it is full of fluid. I was thinking it would quit after it ran for awhile but its still doing it. Any ideas would be a great help thanks.

Check the hyd fluid filter. Any evidence of water in your fluid?

If you raise an implement like a bush hog, then turn off the tractor, does it immediately fall to the ground? If so, it is probably the seal on the 3 point lift bypassing and the position control keeps compensating for the drop. I'm not sure that tractor has position control, but the symptoms sure sound like it.

Yes it drops and drops when I push in clutch it has draft control. When I move draft control it don't do it as bad. Thanks

Draft control can also do this, depending upon the circumstances.

OK I,m checking my manual from I&T shop manuals it don,t say much about what it could be just that it could be gummed up or have trash in it. I guess I,ll pull the cover of and check it out thanks for your input I,ll let you know what I find thanks.
