S18 Stump Blaster
 

Designed simply and ruggedly the S18 has a heavy duty fixed deflector. The simple direct flow hydraulic drive is designed to provide the best torque and RPM to the cutting head. The unique positioning of the rotor allows the operator an excellent view of the grinding action. The S18 is also available with a mini skid steer mount for even better access to tight areas.

Cutting Depth - Below Ground: 10"
Self Feeding - S18

TIP: Grass saver. Since cutting is done by backing away from the stump, and repositioning is usually only a few inches, the S18 causes very little turf damage in the hands of an experienced skidsteer operator.
