The Baumalight 3P40 HPR PTO Stump Grinder is built as a high-performance PTO-driven solution for landowners, acreage managers, and contractors running tractors in the 60–120 HP range with a 1,000-RPM PTO. Engineered around Baumalight’s heavy-duty HPR gear box, the 3P40 delivers exceptional torque transfer—pushing 803 ft-lbs of torque directly from the PTO to the cutting rotor for aggressive, continuous-duty stump removal.

A massive 34-inch rotor equipped with 52 replaceable carbide teeth allows the 3P40 to chew through large hardwood stumps with speed and consistency. The 810-RPM rotor speed keeps the teeth engaged and clearing material efficiently, while the enlarged rotor mass stabilizes bite quality and maintains momentum under load.

The 3P40’s cutting envelope is engineered for real-world land-clearing demands: up to 25 inches above grade and 14 inches below grade, letting operators level, contour, and fully erase stump profiles. In real operating terms, a 24-inch stump is typically ground in just a few minutes. Larger stumps—30 inches wide and 12 inches deep—can be processed in approximately 2 minutes at 120 HP, 3 minutes at 90 HP, and 4 minutes at 80 HP.

Because the drive is direct from the tractor’s PTO through Baumalight’s heavy gear reduction, power is transmitted with minimal loss. This gives the 3P40 the cutting authority of a dedicated stump grinder while leveraging the efficiency and control of your tractor. For acreage clearing, farm maintenance, fence-line cleanup, or property reclamation, the 3P40 stands as one of the most efficient PTO stump-grinding systems available.
