I have a brand new 36" Ferris Hydrodrive walk behind. The dealer informed me that I cannt put a cart behind it since it is only a single drive and alot of the steering is done by me manually turning it, which isnt hard at all but I really need to have a cart behind the mower. Has anyone had any experience putting a cart on a single drive hydry walk behind? Im thinking I might just buy a sulky and have my mechanic make me some kind of attachment for it. Will it Work?
