I'm having some issues with the three-point lift on my 2005 m4900. When I lift an attachment, the 3-point jumps up and down thrashing the tractor around. After looking at the hydraulic system section in the service manual I took the lift system off the tractor and found that the feedback lever shaft was slightly bent. This caused the lever to move hard and stick. I got it freed up, so it moves easy. I put the tractor back together and it still jumps up and down. As far as I can tell, nothing else appeared to be bent or broken. Any ideas?

Sounds typical when rockshaft piston seal has failed. I've heard this referred to a 3 pt hiccupping. Now you need to R&R rockshaft housing again so you can replace piston seal.
