S18 Grinder

The S18 model uses no swing cylinder, flow goes directly to the motor for more torque and has no need for 12 volt DC power.

The S18 is mounted at 90, bring visibility to 100%, and also has a fixed frame so the operator only needs to use controls that he used-to.

 

* 12-25 gpm

* 24 cutting wheel

 

 

 
 
S24 & S28 Skid-Steer Grinders

The cutting wheel is powered by the hydraulic remotes on your Skid Steer and the swing cylinder is controlled with a 12v diverter valve. The off set rotor design for greater visibility and needle valve for precise swing control makes the S24 & S28 comfortable to operate.
34 teeth on a 24 cutter means less cutting for each tooth resulting in longer tooth life and smother cutting for less wear on your Skit Steer.


Units are shipped with standard skid steer quick attach, 12v cigarette light plug, and flat-face quick couplers.  The floating deflector contains the chips and debris and can be swung completely out of the way to cut close to fences.


Grease zerks and replaceable brass bushings provided at major pivot points for extended service life. Heavy tooth population makes finer mulch and allows much smoother operation.
