The 1463B is the standard by which all tub grinders are measured. No other grinder can match its power, (up to 1,650 horsepower) production, or its versatility. It grinds wood waste, green waste, and even tires at unparalleled rates. Since the first one produced in 1988, the 1463B has continued to out-perform the competition, resulting in the industry’s highest resale value. With horsepower ranging from 1,600 to 2,000 h.p. and 120 Lb. hammers, the Diamond Z 1463BT is truly in a class of its own. No other tub grinder in the world can duplicate this massive machine’s ability to reduce scrap tires, including O.T.R. up to 10′ in diameter, stumps and wood waste, green waste, C&D and railroad ties at unparalleled rates. Built to be completely portable, the model 1463BT is the industry leader in production, strength and durability.
