Long 310 Hydraulic lift problem

[bladerunner3]

Hello all,
I have a recently purchased Long 310 or 260 which is a neat little tractor, overall, but has a problem with the hydraulic lift in that it will initially lift an implement, but after reaching the set position, will then lower it, lift it, lower it, lift it, etc.... You get the picture. If there is no implement attached, the lift goes up to the set position and stays there. Any ideas on what could be wrong with it??

i do not know if your joystick has a floating position. i do not know Long tractor. as far as i know,some tractor have four position in the joystick--lift,down,float,stay. when it on the float the 3 point will down and up.

I don't have any experience with a Long, but it sounds like it is "hickuping". The position control senses that the arms are lower than the setting and raises them back up. Then they leak down again, and on an on. I would think you have leakage in the control valving or the lift cylinder seal.
