I have had the same problem since 1977. How the heck to do the install by your self. Well, I have not figured that one out. I have always had to have another person guide the drive shaft while I lift the front. after that it is pretty easy. I have tried to block it but for some reason when I move the tractor it gets bumped and moves everything out of wack and you have to start over. It is better with two people. JAck
