The all-new TG5000 tub grinder features a 60-inch-deep and 12-foot-wide tub opening. Vermeer says the bottom of the tub flares outward from the tub wall, allowing the hammermill to cut under the vertical wall of the tub, helping to reduce bridging and permitting steady feeding of material. Powered by a Tier 3 CAT six-cylinder diesel, the unit boasts excellent power and fuel economy. Engine choices are a CAT C15, providing 540 hp; or a CAT C13, delivering 440 hp. It uses the Duplex Drum, which is equipped with eight angled hammers cutting 16 radial paths.
