I can not get my 3 point hitch to work. The front loader works fine. I’ve screwed the value out two or 3 times and turned back in slowly and still can not get it to work. Once in awhile when I crank it, it will come up but still can not make go down. The value will come all the way out and it does not look like it has any washers or orings or nothing on it. The pic in the book looks like it has washers and things on it. Can anybody help me to get this going. I just bought the tractor, my first and the man said it did work.
