1200XL Tub Grinder

The Morbark 1200XL Tub Grinder is a long-lasting, durable machine that holds its value. This mid-sized grinder features the Morbark Integrated Control System for the ultimate in diagnostics; dual hydraulic tub drive motors for increased torque and greater efficiency; hydraulic augers for quick removal of product from beneath the mill; laser-cut, factory-balanced hammermills with forged hammers for unsurpassed durability and smooth operation; and tub tilt for easy access to grates and anvil for routine maintenance.

Hydraulic Augers

Quickly remove product from beneath the mill. During material surges, pressure sensors on the auger system automatically slow tub rotation to prevent plugging.

Torque Limiter

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

Drum Chipper MICS

Morbark Integrated Control Systems (MICS)

The ultimate diagnostic system; monitors hydraulic pressures, temperatures, clutch systems, tub rotation and engine efficiency while automatically adjusting to maximize performance.


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