Mar 13, 2014· Rayco, Powertek, Beeline ( sunrise concepts) . I really like this style of grinder. There is a learning curve but once mastered you will smoke any one using a Vermeer SC252. These grinders accell in ground speed, tight quarters. I can remove a 48" maple in 15 minutes, a 20" stump in 2 minutes and a 10 in stump in 20 seconds.
