2026 BaumaLight S40 

The S40 stump grinder is supplied with a bent axis piston motor which is the best option in the industry for both efficiency and longevity. 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. Stocked with 12 High speed teeth the massive 1.25” thick steel rotor provides the back bone for the Skidsteer mounted stump grinder. The teeth can also be rotated up to 3 times to provide a renewed cutting surface even in the field and the concave shaped carbide tip of our High-Speed Teeth provides aggressive cutting action.

With a cutting depth per pass of 2 inches, the S40 is designed for efficient and fast grinding by cutting both ways and a fast-swing cylinder speed. This allows for reduced grinding time because with the high swing speed you can quickly chew up those roots that run out from large stumps. This makes the S40 stump grinder for skidsteer a powerful choice for operators looking to maximize productivity. The extra-large Blast shield is designed with dual rows of chain curtains to contain and control chips during grinding. The Blast shield is hinged to give the best protection and chip control throughout the grinding process. This hinge also allows the shield to be raised to get into tight areas and for easy access to the rotor and teeth.
A S40 stump grinder with a motor of S770 having a PSI of 2500 can cut a stump of 24 inches in 8 mins at 40 GPM, whereas the same motor parameter with 3000 psi can cut a stump of 24 inches in 6.5 mins at 40 GPM at 3500 psi the same motor will grind a 24” stump in 4.5 mins and with 4000 psi as some skidsteers offer, the cutting time will be even quicker.
