I went out today to fix my Mother's road and move some dirt but the front end loader will not tilt after going about halfway down. It works fine...tilts up and down fine if I don't tilt it over halfway down. If I go over halfway it just drops the rest of the way and I have to set it on the ground and back up to get it back to halfway and it works again. It's a 2008 New Holland TT775 with a Woods front end loader, 400 hours, hydraulic oil is at level, filter is new. My Mom said the issue started on my Dad the last time He used it (January) before He passed but He didn't tell me so I don't know if anything else happened to it to help diagnose.

Easy way to diagnose seals in cylinder being and is take one line off one side. Put hose in bucket. Bump valve to make sure your not actuating valve to hose side. Then hold lever down cylinder shouldn’t have much fluid come out of port. If a lot comes out then seals on rod piston are bypassing.
Most likely that’s what it is as that’s the common problem.

15yo is about right in my experience for hydraulic cylinder seals to go bad. Once they go bad in one, expect the rest to go bad in the next year or so. Have rebuilt 5 or 6 and its surprisingly easy.
I will say, if they are bad I would expect to see a leak, with oil on the cylinder. If its that unresponsive, I would expect to see a LOT of oil.Last edited by miket; 03-27-2023, 05:32 AM.
