Well, guess what, there was a cultivator attachment just like that listed May 29 on CL. Dalton/Windsor area. In fact both that attachment and a set of disc harrows for the walkbehinds, and the guy only wanted $50 total for the package. What I deal!! Too late though cause I emailed and they're long gone.
Man that brings back some memories. In 1972 I drove a walk-behind that looked like that one through the back of our storage shed... Took out the entire back wall of the shed and I'm lucky the roof didn't fall on me. Man those clutches are sticky for and 11 year old. I'd love to have all of that but I doubt I could get it past the "review committee" lol. Good luck to whoever gets it. It'll be a fun project that I know for sure.
