Morbark Integrated Control Systems (MICS)

Automatically adjusts feed rates and monitors pressures and feed wheel position to maximize production and engine efficiency.

Torque Limiter

The full breakaway torque limiter system protects the engine and clutch against shock and overload without stalling the engine.

Hydraulic Augers

Tub is equipped with hydraulic augers that allow the operator to quickly remove product from beneath the mill. During material surges, pressure sensors automatically slow tub rotation to prevent plugging.


Laser-cut, factory-balanced hammermills with forged hammers offer unsurpassed durability and smooth operation.

Optional Tracks

Bring the grinder to the material with the optional track undercarriage.
