Simple Yet Solid

Each mount locks into the rotor drum with two bolts—no bushings, lock collars, or heavy shafts, and no need for specialized tools like rod pullers. A unique mounting design transfers impact stress to the rotor drum, minimizing bolt stress. Each mount is independently secured, so if one mount is damaged, only one needs to be replaced.

Unmatched Versatility

This exclusive rotor opens more market opportunities by allowing operators to use different mounts, including our KeyKnife chipper mounts. The replaceable mount rotor lets you switch from grinding to chipping without swapping rotors or assembling a complex overlay onto the rotor drum.
