Skidsteer Stump Grinder - S18

The S18 skid steer stump grinder is designed ruggedly with simple operation in mind, with no required electrical connection. The simple direct flow hydraulic drive is designed to provide the best torque and RPM to the cutting head as no flow is diverted to a swing cylinder. The S18 Baumalight stump grinder is offered with three motor options to best match your flow, be sure to check out the Stump Cutting Times charts below to see how fast you can grind stumps with the flow of your skidsteer. The unique positioning of the rotor allows the operator an excellent view of the grinding action and the heavy duty fixed deflector safely directs the flow of debris.
By a quick pull of two pins a mini skidsteer plate can be put on as well.

Carbide Tipped

Like the finest saw blades, the cutting teeth on Stump Blasters are carbide tipped. This incredibly hard material ensures reliable cutting performance. When grinding stumps, buried hazards are inevitable; gravel, stones even metal posts are not uncommon to “find”. Our carbide teeth are designed to stand up to this abuse and keep on blasting stumps to dust.

6 FREE TEETH

All S18 Stump Grinder comes with a free set of 6 replacement teeth. These replacement teeth are conveniently shipped in a robust enclosed compartment on top of the frame.

More Teeth

The high number of teeth means that each tooth needs to do less work. Each of the Stump Blasters teeth only need to make a small cut, because the work is shared by more of our rugged teeth they last longer and usually only require 2 or 3 replacements at a time. The bolt-on designed teeth allow for straightforward replacement.

Multiple Teeth

Hydraulic Motor

Skid steer mounted Stump Blasters run on hydraulic motors. For best results, match your equipments flow rate to one of our available hydraulic motor options.

More Clearance

The Stump Blaster’s carbide teeth extend a full 1-¼ inches from the rotor. This prevents chips and mulch from getting plugged. More chip clearing produces smoother operation and reduces heat build-up that can damage the rotor and cause premature tooth failure.

More Clearance

Rotor

The massive ¾" thick steel rotor provides the back bone for the Stump Blaster cutting system. It’s the anchor for the carbide tipped teeth. For smooth operation it’s important that the rotor remains solid, with no flexing. The rugged rotor also provides the Stump Blaster with the extra momentum needed when the grinding is tough, making sure the Stump Blaster can power through the hardest stumps.

Greaseable Pins

Our grease pins are zinc plated to prevent corrosion which will allow for smoother operation of the units joints over their lifetime.
