Description
High Performance stump removal efficiency starts with the Baumalight GXM550. The GXM550 excavator stump grinder is designed with high performance in mind for 3.5 to 8 ton excavators equipped with 8 to 40 gallons per minute of flow. This robust stump grinder features a 24" rotor and a bent-axis piston motor, ensuring powerful performance. The grinder is equipped with 12 carbide teeth, each rotatable up to three times for extended use. The unique concave tooth design delivers aggressive, precise cuts, reducing wear and enhancing mulch quality.
The GXM550 Baumalight stump grinder is offered with three motor options to best match your flow. A GXM550 with a motor of X510 having a PSI of 3000 can cut a stump of 24 inches in 25 mins at 12 GPM, whereas the same motor parameter and increased PSI of 4000 can cut a stump of 24 inches in 20 mins at 12 GPM. If the GPM is increased to 15, the time taken will be reduced.

Hear From Our Customers
I wasn’t sure which mulcher would match up with my high-flow loader, but their team nailed it. I got a call from a fitment expert within an hour of ordering, and they walked me through every detail.
Heavy-Duty Quality – No Corners Cut
This isn’t cheap imported junk. You can tell the moment you unstrap it from the pallet. Welds are clean, steel is thick, and everything lined up perfect. It’s built for real work, not weekend projects.



Fast Shipping, Fair Price
I’ve ordered attachments before from other dealers and waited weeks. Skid Steer Store had mine out the door in 48 hours, and the pricing beat local suppliers by a mile. No BS, just solid gear delivered quick.
Made My Crew’s Job Easier
We run a small excavation outfit, and this auger attachment saved us a full day of labor on the first job. No leaks, no issues. Showed up crated and ready to go. Will be ordering again when we expand the fleet.

Real People Who Know Their Stuff
Called in with questions about a trenching bucket for a Takeuchi. Guy on the line actually knew what he was talking about. No hold music, no upselling, just straight answers and honest pricing. Hard to find that anymore.
Shipped Right to the Yard – Hassle-Free
I was expecting a mess with freight delivery, but it was smooth as could be. Skid Steer Store coordinated everything and it landed at our yard gate before the next job started. Zero downtime. That’s how it should be.
