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. With horsepower ranging from 1,600 to 2,000 HP and 120 lb. hammers, the Diamond Z 1463BT offers an unmatched 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.
