Excavator mounted Stump Grinder - GXM750

The GXM750 excavator stump grinder is designed with high performance in mind for 7 to 18 ton excavators equipped with 8 to 40 gallons per minute of flow. It Features 20 green carbide teeth packed in groups of 5. The Wearsharp® Teeth can be rotated for a fresh edge up to three times, letting you grind stumps 3 times longer. Heavy tooth population makes finer mulch and allows much smoother operation, while the blast shield with double row chain curtain ensures debris stays put. The 24" rotor is powered by a bent axis a piston motor, which provides ample stump grinding in virtually any location your excavator can reach. The GXM750 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 excavator.

WEARSHARP® 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.

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

6 FREE TEETH

All GXM750 Stump grinders comes with a free set of 6 replacement teeth. These replacement teeth are conveniently shipped in the owner’s manual bag attached to the frame.

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.

Rotor

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

Blast Shield

The extra-large blast shield provides maximum chip and debris control with a dual row of safety chain curtains. The blast shield can also be used for cleanup and back filling without getting out of your cab.
