It's not a plow, I've seen 'em, but darn if I can put a name on it right now. It's not a harrow, but they were used in the garden to cut the furrow between the rows of corn or what ever veggies were planted. Also used the same way weeding between the rows. I found a picture, and now remember the name, because it's in the picture. It's off of a cultivator, and I include photos. And the next photo shows a guy riding on a larger one.
