By matching a motor to your skid steers hydraulic flow these high efficiency motors make the most hydraulic power transforming it into the highest available stump grinding performance - the Baumalight S40 Skid Steer Stump Grinder. Engineered with an industry-leading bent-axis piston motor, this attachment maximizes your skid steer's hydraulic flow to deliver superior stump grinding performance. The sturdy 1.25” thick steel rotor, fit with 20 high-speed three-sided teeth, ensures efficient and sustained cutting over heavy use.

A S40 with a motor of S740 having a PSI of 2500 can cut a stump of 24 inches in 30 mins at 20 GPM, whereas the same motor parameter and increased PSI of 3000 can cut a stump of 24 inches in 25 mins at 20 GPM and for PSI of 3500 with same specifications time taken will be 23 mins. If the GPM is increased to 25, the time taken will be reduced.
