My neighbor had on set up on an old caddy....We had a Farmall super M on a 3 point hitch. There son was about a year younger than me once they let us do all the firewood processing the super M was the ticket. We would pull the logs to a concrete slab and processed everything there. (Man I wish thats all I had to do now)
