1600 Tub Grinder

The largest tub grinder on the market, the Morbark 1600 Tub Grinder is able to power through and reduce materials from large land clearing or organic/wood waste programs. With an 11’2″ tub diameter, 15′ tub opening and a capacity of 20 cubic yards. With horsepower ranging from 1,050 to 1,200, this machine can power through tons of raw materials from large land clearing projects and organic/wood waste processing. The Morbark Integrated Control System (MICS) monitors key systems while maximizing performance. The remote control allows you to quickly adjust feed systems for top production rates and fuel efficiency. With laser-cut, factory-balanced hammermills and three 16″ diameter hydraulic augers to quickly move product, this tub grinder gives you optimum production.

Remote Control

Allows the operator to quickly adjust feed systems to obtain maximum production rates while keeping engine load constant and fuel consumption to a minimum.

Hydraulic Augers

Durable, hard surfaced steel augers quickly remove product from beneath the mill. Pressure sensors on the auger system automatically slow tub rotation to prevent plugging.


Laser cut, factory balanced mill with forged hammers provides optimum grinding power.
