Hydraulic Stump Grinder
Excavator mounted Stump Grinder - S18
The S18 skid steer stump grinder is designed to go on both skidsteers and small excavators. With a quick pull of two pins, a standard size skidsteer plate can be put on as well. The 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. 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. A S18 with a motor of S450 having a PSI of 2500 can cut a stump of 24 inches in 60 mins at 12 GPM, whereas the same motor parameter and increased PSI of 3000 can cut a stump of 24 inches in 50 mins at 12 GPM. If the GPM is increased to 15, the time taken will be reduced. The unique positioning of the rotor allows the operator an excellent view of the stump grinding action, and the heavy duty fixed deflector safely directs the flow of debris. Cutting depth is up to 10" below ground. Our grease pins are zinc plated to prevent corrosion which will allow for smoother operation of the units joints over their lifetime.

Excavator Mount
This optional mounting plate is perfect for welding to your skid steer’s unique fitting.
Or you can order a turn key mount, see our excavator mounting page
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.
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.
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.
