Dosko’s new 337S Swivel Grinder features a swiveling grinder head that allows for easy sweeping action of grinding head. Simply wheel the stump grinder to the stump, engage the single lever wheel lock, and grind the stump with the swivel action gliding left and right over the stump. The side discharge keeps grindings away from the machine and the operator. Grinding a stump has never been so easy!
