One of these days, Real Soon Now, I'm going to fabricate different shanks for the scarifier teeth. The ones I got from the box blade are a little too short in the lower (mostly horizonatal) portion, and when I try to fill the rake, a lot of stuff rolls off to the front instead of curling to the back. I need shanks that are longer at the leading edge and with a little more curve. It's a digging fool, though, at least in the Florida sand. Sort of like extra aggressive bucket teeth.
