The Mighty Giant Model 3100 Power Units

The Mighty Giant Model 3100 Power Unit is designed for heavy duty commercial use. The tub tilts hydraulically (something we’ve been doing for over 50 years) for easy access to the hammers and screens. A multi-function remote control system is standard on all grinders. Screens are available in a wide range of sizes, with custom configurations available because we fabricate our own screens. The 14” discharge auger under the mill allows trouble free grinding with less mess under the machine.

Features:

  • Tub opens hydraulically for servicing and changing the screens.
  • Tub hydraulic system uses a variable displacement hydrastat pump with electronic speed control for forward and reverse. Tub is chain driven.
  • Trouble free high capacity 14” discharge auger
  • Elevators drive from the top with a rubber lagged pulley.
  • Elevators hydraulically fold and unfold, hydraulically raise and lower, and hydraulically swing side to side to make a wider pile or to fill trucks.
  • Hammers have hard surfacing on all 4 edges so that they can be turned 4 times to use all 4 corners.
  • Available with gooseneck hitch and hydraulic brakes. This unit has tandem axles with dual wheels.
  • All engines have a heavy duty air filter system with precleaner and a muffler on the exhaust system. All engines have a completely enclosed engine compartment
