I bought a B8200 recently and the loader and the 3 point lift worked fine. Yesterday I was operating a tiller and wanted to back up. When I tried to lift the implement it would only come up in short increments, and it sounded as though the valve might be opening and closing, or something was bypassing. In that condition the loader behaved the same. However, after I stopped the tractor and restarted just a few minutes later, the hydraulics to both implements worked for awhile. But after tilling for awhile, the problem repeated, and also cleared up when I stopped and restarted the tractor again. I know nothing about hydraulics. Help?
