Old Plow ID

Does it look something like this? This is called a disk tiller. Kind of an intermediate between a disk and a disk-plow. Does a terriffic job of cutting up hard sod! This one looks like the lift is manual - with the rear facing crank. The one we had had a hyd. cylinder there. Note the very heavy cast wheels. When you pushed the hydraulic lever, this thing was going down! We usually went over a field twice. Second pass at 90 degree angle to first. Sod was then very effectively cut up. Second pass was a pretty rough ride, however!

I didn't quite follow, were you suggesting this machine was built by someone else for John Deere. Or have I got that all wrong? How old does this disc appear to be? When I bought mine not a lot of companies were building off sets. Does this disc use a standard 8 inch stroke implement cylinder? I am just raising these questions, thinking it may spark someone's memory. All of a sudden someone will say, I remember that.
