It has a JD self leveling loader (245 I think) and has been started alomost every day. The down sides to it are the loader - it isn't anywhere near strong enough for the tractor and the hydraulics. The hydraulics have never worked properly. It always acts like it is starved for oil. The loader raises with a lot of vibration and it is often necessary to open up the throttle to get the loader up. Even when still under warranty the dealer couldn't solve the problem after several tries so I have lived with it.
Does your loader hydraulics dump back in the remote valve block or does it dump in the filter housing?
A friend of mine has a JD (older model) and had the vibration like you wrote about. His loader was plumbed to dump in the remote block on the back of the tractor. I helped him find a hydraulic filter bowl that has a port that you can use as a return. He got it all hooked up last week and it's working like a charm now. First thing he said was "after all these years". After changing over to the new bowl he turned the pump pressure up a little and the loader works great now.
It dumps back into the filter housing. Also if it has the wrong type of valve, the selling dealer installed it prior to delivery so I doubt that is the problem.
