I have been using this electric hoist from harbor freight
for almost two years now.
My barn has a large beam on two telephone poles that supports the front of my covered parking area. I used some towing chain looped around the beam and then run through a piece of steel pipe that fits in the mounting brackets on the hoist. It has no trouble lifting the front end of my 60 inch exmark. Makes blade changes go much quicker and no stands or ramps to get in the way.
I would be wary of using a winch for this purpose, they aren't really designed for dead lifting straight up.
