The Baumalight GXM750 is a professional-grade excavator stump grinder engineered for operators who demand strong hydraulic performance, fast cycle times, and reliable cutting force in demanding land-clearing environments. Designed for 7–18 ton excavators and capable of running on 8–40 GPM of hydraulic flow, the GXM750 converts excavator power into aggressive cutting action with industry-leading torque efficiency.

The GXM750 features 12 high-speed carbide teeth, arranged in groups of three for balanced, consistent cutting engagement. Each tooth can be rotated up to three times to provide a fresh cutting edge, extending field life and reducing downtime. The concave tooth geometry chips material cleanly and progressively, minimizing bite shock and allowing the rotor to maintain speed through hardwood, frozen ground, and oversized stumps.

The heart of the attachment is a 24" cutting rotor powered by a bent-axis piston motor, delivering exceptional torque density and responsiveness across a wide range of hydraulic setups. The rotor’s 1.25" thick steel core provides the mass needed to sustain cutting momentum while eliminating flex, ensuring smooth operation even under high load.

The blast shield—equipped with dual rows of chain curtains—contains chips effectively, increasing operator safety and improving visibility on job sites where debris control is essential.

Real-world performance is where the GXM750 stands out. With a motor configuration equivalent to an X570 running 3,000 PSI, the grinder can remove a 24" stump in approximately 7 minutes at 30 GPM. With the same setup at 4,000 PSI, the time drops to 6 minutes at 30 GPM. Increasing flow to 35 GPM improves productivity even further, allowing operators to shorten cycle times and maximize output on high-pressure excavator circuits.

Built for forestry cleanup, site clearing, municipal work, right-of-way maintenance, and property reclamation, the GXM750 delivers the hydraulic efficiency, durability, and cutting precision required by professional excavator operators. With heavy-duty construction, smooth rotor dynamics, and configurable motor options, the GXM750 stands as one of Baumalight’s most capable and adaptable excavator-mounted stump grinders.
