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 track undercarriage makes it easy to bring the grinder right to the material.
Optional Tracks - Bring the grinder to the material with the 330L Cat undercarriage with 700mm double grouser shoes11 PSI ground pressure, 1.4-2.4 MPH ground speed, 22.5″ clearance.
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 - Quickly remove product from beneath the mill and during material surges, pressure sensors automatically slow tub rotation to prevent plugging.
Hammermill - Laser-cut, factory-balanced hammermills with forged hammers offer unsurpassed durability and smooth operation.
