High Performance Skid Steer Stump Grinder - S40

The S40 stump grinder is mounted with a bent axis piston motor. By matching a motor to your skid steers hydraulic flow these high efficiency motors make the most hydraulic power transforming it into the highest available stump grinding performance. Stocked with 20 carbide Wearsharp® Teeth the massive 1.25” thick steel rotor provides the back bone for the Skidsteer mounted stump grinder. The high number of teeth means that each tooth needs to do less work. Each tooth only needs to make a small cut, because the work is shared by more of these Wearsharp® Teeth, which last longer and typically only need 2 or 3 replaced at a time. The bolt-on designed teeth allow for straightforward replacement. The teeth can also be rotated up to 3 times to provide a renewed cutting surface even in the field.

The extra-large Blast shield is designed with dual rows of chain curtains to contain and control chips during grinding. The Blast shield is hinged to give the best protection and chip control throughout the grinding process. This hinge also allows the shield to be raised to get into tight areas and for easy access to the rotor and teeth.

By Green Manufacturing, Inc.

The unique design of the Wearsharp® allows the tooth to retain a sharp cutting surface, unlike traditional teeth that tend to round over. This provides a consistent cut throughout the life of the tooth, allowing you to maintain a faster sweep speed. This round tooth is 3 teeth in 1. Simply loosen the lock nut and rotate the tooth to a fresh, sharp cutting edge. This can be done three times, extending the life of each tooth.
