bouncy 3 point lift arms on L2550.

Thank you. Sorry I am not responding very well. I had to take some time off to have a cancerous tumer removed from colon.

Ok, so it happens while lifting an actual load. Does it only stutter on the way up and once you stop raising it it stays there normally?

It probably has something to do with position control. I dont know if theres a way to disable that function in order to test that theory. I dont know if its relevant but apparently draft control was optional on that tractor and had a separate lever behind the 3pt lever. Does yours have that?

It shakes at any point when you stop lifting. I do not have the draft option. Thanks for your reply.

The lowering speed valve closes off the hydraulic circuit between the lift cylinder and the position control valve.

If the lift holds with the lowering speed valve closed the lift cylinder is not leaking.

That would suggest the leakage is in the position control valve or a component between it and the lowering speed valve.

Thank you for the input. Lifting holds ok with lowering speed valve closed Even overnight. With the lowering valve closed I can still raise the implement but only at a point maybe 3/4 up to the top.
