Ok I was mowing yesterday and the mower just stopped. Hydro fluid is full I can hear a whine from the pump. I will try replacing the filter on monday But I'm clueless as to why it will not run.I didn't get a book on it and the neighbor who was my ace in the hole,on farm repairs, rudely deceided to die on me. Oh well wanted to be with Jesus I guess. The farm shop for this machine is a long way away and they most likely will not be able to work on it for several weeks and the hay is ready. Any help would be gratefully needed.
