The Baumalight S14 Stump Grinder is engineered specifically for mini skid steers and compact excavators that demand reliable cutting performance in tight-access job sites. Built around a direct-drive hydraulic motor, the S14 delivers strong, uninterrupted torque to the cutting head—ensuring fast, predictable stump reduction without the power losses common in swing-cylinder designs.
At its core, the S14 uses a compact rotor equipped with rotatable round carbide teeth, giving operators aggressive cutting action while reducing downtime associated with sharpening or replacement. These teeth maintain a consistent bite through hardwood, root systems, and mixed soil conditions, extending tooth life and improving operating efficiency over long project cycles.
The S14 can be mounted using a quick-change mini skid steer plate or optional excavator adapters, allowing operators to leverage the attachment across multiple carriers. With a maximum cutting depth of 10 inches below grade, the S14 is optimized for property maintenance, landscaping, residential clearing, and tight-area access where larger grinders can’t maneuver.
Direct-Drive Hydraulic Performance
The S14’s direct-flow hydraulic motor channels 100% of available hydraulic flow into the cutting head—no diversion to swing mechanisms—maximizing torque output and maintaining consistent RPM under load. This design ensures smooth, stable grinding even on lower-flow carriers, making the S14 ideal for mini skid steers operating in the 10–20 GPM hydraulic range.
In field testing:
- At 12 GPM and 2,500 PSI, a 24-inch stump can be ground in ~50 minutes
- At 12 GPM and 3,000 PSI, the same stump is reduced in ~40 minutes
- Increasing GPM to 15+ significantly reduces total processing time
These performance characteristics give operators reliable timelines for job scheduling and productivity planning.
Compact Design for Tight Work Areas
Weighing under 300 lbs with streamlined geometry, the S14 fits easily through gates, around fencing, between landscaping structures, and along property edges. Its compact footprint allows precision cutting in areas that are inaccessible to larger skid steer or tractor-mounted stump grinders.
