Cool project plastikosmd. I did this exact thing (sort of) last winter/spring. I found a cherry Haban for an old school Case garden tractor. I think it was made in the late 60's. My tractor being a newer (1990) 448 and the current hitch type, things needed re-engineered and fabed. I mounted and used it during spring. Over this winter I'm going to "restore" it and re-engineer the lifting mech to something a little more modern and easier. Given the laws that govern these, I'm sure these units are older as well. I was surprised at how well engineered the Haban was.
