1100 Tub Grinder

The Morbark 1100 Tub Grinder is a mid-sized grinder that brings price and performance together for the processing and reduction of wood waste. This tub grinder packs an impressive line of features usually only found on larger models, including the Morbark Integrated Control System (MICS) to adjust feed rates of a variety of materials while optimizing fuel efficiency. Other features include a laser-cut, factory-balanced hammermill; dual hydraulic augers that maintain flow during material surges to prevent plugging; and a full breakaway torque limiter to protect the engine and clutch from catastrophic damage.

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.

Tub Tilt Feature

Tub Tilt

Provides easy access to grates and anvil for routine maintenance.

Hammermill

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

Morbark Integrated Control Systems (MICS)

Monitor pressures, temperatures, clutch systems, tub rotation and engine efficiency to maximize production and engine efficiency.
