When I moved back into my parents' place about 5 years ago, my dad had a one wheel cultivator in the chicken coop.
Hadn't run in years and years and I barely remember him ever using it.
It seems he may have used it to hill his potatoes but not sure
I'm embarrassed to say that I needed the chicken coop for chickens and moved this machine out into the weeds.
Stumbled across it yesterday and found a plate.
Great Lakes Tractor Co in Ohio and it says Chief.
As far as I know, it is just a cultivator.
There are 4 or 5 straight times on the back
Not sure what engine it has but the serial number is readable.
Not a lot of stuff online about either Great Lakes or this machine
Some here have some knowledge of it.
Since I'm retiring in a couple months, I was thinking of seeing if I could get it running
