Mighty Giant menu

The Mighty Giant Model 2015 PTO Driven tub grinder is the most durable, highest capacity PTO tub grinder in the industry and it is designed for heavy duty commercial use.  The tub tilts hydraulically  (something we’ve been doing for 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.


  • 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. 
  • 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.
  • Pin hitch chassis with tandem axles and hydraulic brakes on both axles.
  • Capable of grinding any type of Forage or Grain
  • Hand held remote control allows the operator to control tub and elevator functions from the loader  tractor.
  • Highest capacity, most durable PTO Hay Grinder available
