L3901 3 point issue

[OldcrowP51]

I noticed the 3 point on the L3901 oscillates when at idle no implements attached.
Also noticed with tractor off the 3 point drops with the control lever in up position.

You need to consult the WSM on how to test it.
Sounds like you could have a problem with the three point piston seals.

Almost certainly the problem.
