It’s been more than 40 years since Universal Refiner Corporation (URC) built their first grinder. Their outside design looks somewhat like a tub grinder. The grinding action is labeled, H.A.W.G. (Hypocyclonic Action Waste Grinder) by URC. The “tub” turns in the opposite direction than the arbor cutting disk. This “action” will process large stumps, palm, shingles, railroad ties, green waste, carpet and C&D. There is very little screen wear in a URC grinder. Universal Refiners can utilize less horsepower than conventional grinders and the simplicity of the unit is unmatched.
This grinder will grind 4′ stumps and chunks all day at 50 yards per hour. Reversing Radiator Fan. New Impact Blade System Cutter Disk (250 hours on Disk). Auto Reverse on Pan. Oversized Hopper (custom build that can be removed with a wrench). Average fuel burn on brush is well under 8 gallons per hour.

These grinders aren’t exactly tub grinders, horizontal grinders or shredders. They are more durable, maintenance friendly and grind the nasty stuff with less horsepower than anything you can name.
