Greetings.... my first post. The bucket on my friends Case 1845 has suddenly stopped rolling in either direction at a normal speed. It seems to have reasonable power but barely moves. The boom moves perfectly normally, power and speed. When I am moving the boom up or down and try to roll the bucket at the same time the bucket is back to normal rolling speed, but as soon as I stop moving the boom the bucket roll speed goes back to a crawl. I am trying to figure out how to eliminate possible problems to narrow down the exact cause. Any ideas? Thx, al.
