Have NO idea where it came from or who made it.......... However.....
It appears to me that it has some kind of a spring loaded break away shock system of some kind.
Possibly was made to use in a gang type implement. With multiple of these diggers.
I would invent some sort of 3pt frame adapter to bolt it to and get it dirty..........
Good luck
Not a clue actually. It doesn't look like it was meant for a 3PH. Maybe a mid mount on a Farmall cub or the like. Might be one of a pair to cultivate both sides of a row. Is that a spring trip mechanism?
John Deere 790 with loader LS xr3140h also with loader plus a cab
That is what it looks like to me is a piece off of some other implement..... like the cultivator shank with a big duckfoot shoe that went in the middle of the front/rear gangs on old IH disc that we had years ago
