Holiday Gift Guide Baumalight S40 High Performance Stump Grinder For High Flow Skid Steers Series [aIq5F6mN]
Maximum Power & Efficiency for Demanding Jobs
The Baumalight S40 High-Performance Skid Steer Stump Grinder is designed for serious operators who need top-tier power, speed, and chip control. Outfitted with an industry-leading bent axis piston motor, this unit converts your skid steer’s hydraulic output into maximum torque for rapid stump removal. Matched to your flow specs, the S40 grinds through tough stumps with ease using a 1.25" thick steel rotor and 12 aggressive high-speed teeth.
Bent axis piston motor – highest efficiency and durability
2" cutting depth per pass with dual-direction grinding
Dual swing cylinders for smooth and fast operation
Optimized for high-flow skid steers – up to 40 GPM and 4000 PSI
Built Tough with Visibility and Safety in Mind
The dual swing cylinder design allows better control and faster root grinding. The rotor's massive thickness ensures momentum for cutting, while the dual-row chain curtain Blast Shield protects you and contains debris. The hinged shield also swings up for easier access to tight spaces and simplifies maintenance.
Excellent operator visibility for precision work
Extra-large blast shield with dual chain rows for chip control
Hinged design for access and tight area grinding
Double-shielded hydraulic hoses for added safety
Durability, Simplicity, and Easy Maintenance
Designed for professional-grade use, the S40 includes high-speed carbide-tipped teeth that can be rotated up to three times for extended life. The bolt-on design allows quick in-field replacement. A built-in compartment stores 3 FREE replacement teeth and 1 extra holder. AUX electrical plug is standard, or add the D004460 hand control for older skid steers (USD $276.49).
Rotor: 1.25” thick steel – ultra-rigid and powerful
Free teeth kit included for convenience
Auxiliary electrical plug standard for easy in-cab control
Optional hand control adapter available for legacy machines
