My M8540 is eight years old and I can't seem to keep it out of the shop. Henderson Implement in Lake Charles, La. changed the clutch pack out and they did such a wonderful job I was bragging on them till a week later I went to hook up the bush hog and the 3 point wouldn't lift up. I'm not sure if the mechanic didn't hook something up or if I have a whole new issue. Anybody have any thoughts while the shop is working on it????
