3800XL Wood Hog Horizontal Grinder

We’ve designed the Morbark 3800XL Wood Hog to be the best horizontal grinder on the market. A larger, more aggressive hammermill and independent drive motors on the feed-wheel and belt-chain result in a continuous feed with higher production, greater fuel efficiency, and a more consistent end product. The 3800XL Wood Hog will dramatically increase your production capacity and operating efficiency.

Morbark Integrated Control Systems (MICS)

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


Laser-cut upturn rotor, factory-balanced with T-1 hammers, offers unsurpassed durability and smooth operation.

3800XL Infeed

Feed System

Internal planetary drive with no chains and sprockets means lower maintenance, more torque and better durability.

Externally Adjustable Break-Away Torque Limiter Optional

Flexible, easily adjustable torque limiter helps protect the driveline and hammermill for damage.
