I recently came across what looks to be a modified SB model 33? It's been set up as a scarifier with an adjustable front roller and a hex shaft with locking nuts either end. I originally wanted to build a groomer using a 17" SB45 however this unit already has a hex shaft all set up, which will mean a lot less work for me all that will be required is to buy a new set of blades and spacers or machine up some new spacers out of thick pvc pipe like they've done.
