Mini Skidsteer Stump Grinder – S16

The S16 Skidsteer stump grinder features a specially designed electric actuator that controls the swing of the stump grinder. Equipped with high-performance electric linear actuators (12VDC) and limit switches, the actuator body is made of 304 stainless steel and has an IP69 rating. What sets this stump grinder apart is that it both has side to side swing and all the hydraulic oil from the mini skidsteer goes to the cutting head, the side-to-side swing is powered electronically, which greatly improves overall efficacy. The stump grinder's rotor has double-side tooth setup that speeds up the grinding process, with each tooth only needing to make a small cut thanks to the high number of teeth. This means the teeth last longer and usually only require 2 or 3 replacements at a time. The stump grinder can cut up to 6 inches below ground with a swing radius of 58 degrees. The concave-shaped carbide tip of the high-speed teeth provides aggressive cutting action by chipping the brush bit by bit. The S16 model is ideal for mini skidsteer stump grinding on close-cut grass because the unit can sit stationary as the head swings from side to side.
The rotor's unique positioning gives the operator an excellent view of the grinding action, and the heavy-duty fixed deflector safely directs the flow of debris. The S16's size and dedicated mini skidsteer mount make it a great stump grinder for better access to tight areas, and it's a nice addition to the rental offering on a mini skidsteer. The S16 comes with a C508 26 cc 10-18 GPM Bent Axis Piston Motor having a max PSI of 5000.

AUX Plug

The S16 comes with an AUX cable that will plug right into the 14 pin AUX plug on your mini skidsteer if it’s equipped with one.
This will allow you to control the grinder from your built-in controls on the mini skidsteer.

AUX Plug


If your mini skidsteer is not equipped with an AUX plug, don’t worry. We offer an optional
hand control adapter. Connect the hand control to the attachment AUX cable,
connect it to 12V, and now you can still control the stump grinder from the operator platform.

12-volt electric actuator powered swing

The S16 as an electric actuator which really boosts productivity because all of the hydraulic flow and pressure can go directly to the motor. The power to swing the head is drawn from the 12V battery in your skidsteer which can recharge while repositioning.

All S16 Stump Grinder comes with a free set of 6 replacement teeth. These replacement teeth are conveniently shipped in the owner’s manual tub bolted to the frame.


More Teeth

The high number of teeth means that each tooth needs to do less work. Each of the Stump Grinders teeth only need to make a small cut, because the work is shared by more of our rugged teeth they last longer and usually only require 2 or 3 replacements at a time. The bolt-on designed teeth allow for straightforward replacement.

More Teeth


The massive ½" thick steel rotor provides the back bone for the Stump Grinder cutting system. It’s the anchor for the carbide tipped teeth. For smooth operation it’s important that the rotor remains solid, with no flexing. The rugged rotor also provides the Stump Grinder with the extra momentum needed when the grinding is tough, making sure the Stump Grinder can power through the hardest stumps.



The concave shaped carbide tip of our High Speed Teeth provide aggressive cutting action by chipping the brush bit by bit. This round tooth is 3 teeth in 1. Simply loosen the lock nut and rotate the tooth to a fresh, sharp cutting edge. This can be done three times, extending the life of each tooth.
