Model 5012

The Mighty Giant Model 5012 features a hydraulic fork as standard equipment, allowing the operator to load the material to be ground into the tub and to control the entire grinder from the comfort of the Operator Control Center. In addition, the tub tilts hydraulically (something we’ve been doing for over 50 years) for easy access to the hammers and screens. Model 5012 machines are equipped with a swinging elevator system as standard equipment. Screens are available in a wide range of sizes, with custom configurations available because we fabricate our own screens. The Model 5012 is equipped with a Caterpillar engine. These engines are covered with Caterpillar’s 5 year /5000-hour Extended Service Coverage. The 14” discharge auger under the mill allows trouble-free grinding with less mess under the machine.

Standard on every Mighty Giant – from the PTO Model to the Hydrafork – is the hydraulic opening tub for easy access to the mill, hammers and screens.
