Can't help with that one but I can welcome you to the forum. Can you elaborate on the jerking? Does that tractor have a hydro or gear tranny?

So both the MF 399 and yours both do the jerking when they are pulling something. Does it do it in all gears? Sounds like you might be in to high of gear. That will cause jerking ...but I'm guessing you know that already. Interesting, but I can't think of any possible cause right off. Can you give us any more info on this issue?
And welcome to Net Tractor Talk. I'm glad you found us. :D

It sounds like maybe the universal joints have been reassembled out of phase with each other? That can cause considerable vibration, there is a thread or two or three on here discussing replacing u joints on an RTV that go into the issue. Hopefully it is something that simple.
