I have an idea to take an old deck that I can get for next to nothing and modify it to create a pull behind mower. My current push mower has a 6.5 hp motor but the chassis is shot. I would like to take that motor and hook it up to a deck and buy a new push mower. Has anyone tried this? Is it even worth trying to do? How big of a deck can that size motor pull? Does anyone have an old pull behind that needs some work that they might be interested in selling? Anyone have any thoughts?
