Its a spring tooth harrow like others said, I had a friend of mines dad in high school had found one on an old place they boughtwhile cleaning up. It was about 8 feet wide but a tree had mushed the frame in the past. he was about to scrap it which shocked me. The maThe dad told me it wasnt any thing but scrap then I made a bet that I could make a handy tool out of it. They were cleaning up with an old Jubilee Ford and had a time with the roots and sticks and briars. I offered to build him a 3 point mount tool bar from some tubing they had laying around. I mounted all the teeth on the bar close together making a landscape rake of sorts. I won the bet they clean an entire farm raking debris afterwards with that rake. I saw it sittnd be hind a new Newholland lastweeknd.
