950 Tub Grinder

Compact and easy-to-haul, Morbark 950 Tub Grinders are ideal for converting yard and wood waste, pallets and other mixed woody feedstocks into saleable products. The 950 tub grinder is equipped with a proven drive line protection system that protects against catastrophic damage from contaminants. Hydraulic augers quickly remove product from beneath the mill; laser-cut, factory-balanced hammermills with forged hammers offer smooth operation; full breakaway torque limiter protects the engine and clutch against overload without stalling; and tub tilt provides easy access to grates and anvil for maintenance.


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

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.
