built this scarifer yesterday. has slots for 9 teeth, though there are only 5 in the picture. works great. picture was from test run, just needs paint now.
Awesome design Bulldog!
What I like best is the way you've built it if you needed to add weight you could always fab a "shelf" on the back too in order to put say a cement block or 2 without going overboard.
Where did you get your teeth from?
