I have a roto-tiller for an ST-12, currently set up for an 8 hp Tecumseh (the Briggs shot craps), and dozer blade, 3-point hitch, a disc harrow, and complete front axle with wheels, and a few other bits and pieces. All in working condition and free for a good home if you came and get them. I need the room more than the parts and, if no one wants them they will be "recycled".
