1300B Tub Grinder

The Morbark 1300B Tub Grinder combines heavy-duty construction with the latest technology, including the Morbark Integrated Control System, which allows you to monitor critical machine parameters. With a full breakaway torque limiter system, hydraulic augers and a laser-cut hammer mill, the 1300B tub grinder is the most popular grinder on the market. Replaceable, one-piece anvil and tub floor wear plates make maintenance easy and reduce downtime. The optional 330L Cat undercarriage makes it easy to bring the grinder right to the material.

Morbark Integrated Control Systems (MICS)

Morbark Integrated Control Systems (MICS)

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

950 Tub Torque Limiter

Torque Limiter

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

1300B Tub Augers

Hydraulic Augers

Quickly remove product from beneath the mill and during material surges, pressure sensors automatically slow tub rotation to prevent plugging.

1300B Tub Hammermill

Hammermill

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

1300B Track Tub Tracks

Optional Tracks

Bring the grinder to the material with the 330L Cat undercarriage with 700mm double grouser shoes: 11 PSI ground pressure, 1.4-2.4 MPH ground speed, 22.5″ clearance.
