High flow Skidsteer Stump Grinder - S28

The S28 skid steer stump grinder is designed for high flow and higher horsepower skid steers. Baumalight’s most powerful model, the S28 adds a high volume hydraulic motor and a gearbox that increases the torque to the cutting head giving you the best of precision, power and speed in your stump grinding. Cutting depth is up to 15" below ground with a swing radius of 63 degrees. The floating deflector safely directs the flow of debris for quick clean up. With it’s swing cylinder the S28 is a good choice for skidsteer stump grinding on close cut grass such as golf courses as well as for stump grinder rental on large skidsteers and track loaders. The high number of teeth means that each tooth needs to do less work. Each of the Stump Grinders 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. The massive ¾" thick steel rotor provides the back bone for the Stump Grinder 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 Grinder with the extra momentum needed when the grinding is tough, making sure the Stump Grinder can power through the hardest stumps. The Stump Grinder'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.
We offer 8 pin and 14 pin AUX electrical plugs as well as the 7 pin Bobcat so you can use the controls in your cab with no extra wiring or hand controls.

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.

Carbide Tipped

6 FREE TEETH

All S28 Stump Grinders come 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.

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.

Flow Control

Fine tune the performance of your Stump Blaster easily with the Flow Control knob. The Flow Control allows you to adjust the cutting pass speed, to match the size and performance of your tractor. This gives you the smoothest cut possible and with the full return back to the start position, the quickest overall stump grinding time possible.

Flow Control

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

Floating Deflector

The deflector floats as you grind providing chip and debris control from first cut to maximum depth without getting in the way. In tight grinding situations the deflector can be flipped up out of the way.
