There are different size stump grinders ranging in power from 5 to 100 horsepower. Most smaller stump grinders only grind to ground level. If you want to plant grass after having a tree stump removed, then the stump will need to be grinding at least 6″ into the ground.
Our Carlton SP7015 Stump Grinder has a 27″ cutting wheel powered with 60 horsepower, grinding down 12″ – 15″ into the ground with a 70″ cutting arc. It is the most powerful self-propelled stump grinding. Its runs on tracks and can fit through a standard 36″ gate, with a minimal damage to grass.
