Power Meets Precision in High Flow Applications


The Baumalight S28 Skid Steer Stump Grinder is built for high flow and higher horsepower skid steers, offering unmatched power, speed, and performance. With a 15" cutting depth and a wide 63° swing radius, it tackles even the toughest stumps with ease. The combination of a high-volume hydraulic motor and torque-boosting gearbox makes this Baumalight’s most powerful model.

  • High-flow hydraulic motor for maximum torque and output
  • Precision control with integrated flow adjustment
  • Floating deflector manages debris for quick cleanup
  • Universal AUX plug included – 8 pin, 14 pin, or 7 pin Bobcat ready
  • Optional hand control available for older machines ($276.49)

Durable Design with Maximum Cutting Efficiency


The ¾" thick steel rotor anchors the cutting system, supporting 52 carbide-tipped teeth that extend 1¼" from the rotor. This layout ensures better chip ejection, less clogging, and smooth grinding through the hardest materials. More teeth means each does less work, extending service life and making replacements quick and easy.

  • Carbide-tipped teeth handle rocks, roots, and buried hazards
  • High tooth count means longer wear and fewer replacements
  • Bolt-on design for fast tooth changes
  • 6 FREE replacement teeth included in secure onboard storage

Built to Last, Built for Results


Engineered for heavy-duty use, the S28 comes equipped with a floating debris deflector, zinc-plated greaseable pins, and chrome-vanadium spring bushings at pivot points for lasting durability and performance. Designed for large skid steers, it’s ideal for operators, contractors, or rental companies needing serious stump removal capability.

  • Floating deflector controls chips while grinding
  • Greaseable pins resist corrosion and reduce wear
  • Chrome-vanadium hardened bushings on all pivots
  • Flow control knob fine-tunes cutting speed for best results
