- Model 2015 - PTO Driven Tub Grinder


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.
