DESCRIPTION
Take your stump removal to the next level with the Baumalight S18 and S24 Skid Steer Stump Grinders built tough, designed smart, and engineered for peak performance in landscaping, land clearing, and forestry applications.
Whether you're a professional tree service, contractor, or landowner managing your own property, the S18 and S24 give you precision, power, and durability where it matters most. With cutting depths of up to 15 inches, swing capability (S24), and hydraulic flow compatibility from 12 to 40 GPM, these stump grinders are tailored to handle everything from light-duty jobs to heavy-duty clearing.
The S18 model delivers raw, no-frills performance through a direct hydraulic drive, requiring no electrical hookups ideal for simplicity and reliability. The S24, on the other hand, brings advanced control to your fingertips with hydraulic swing cylinders, integrated flow control, and electrical interface options, including Bobcat 7-pin CANBUS compatibility.
Both units feature heavy-duty ¾" steel rotors, carbide-tipped teeth, and high visibility rotor placement to ensure efficient grinding and operator confidence. If you're looking for a skid steer stump grinder that’s fast, field-ready, and built for years of use, look no further than Baumalight’s industry-proven solutions.
