The H-1130 Big Bite tub grinder is Haybuster’s heavy-duty PTO grinder. It is designed with the features and the durability you need in a 11’ tub grinder. Some of these features include tub tilt, heavy hammermill with 1⁄2” plates and 1⁄2” hammers along with 1 1⁄4” rods, dual augers and a 26’ long stacking conveyor. The 315 hp drive system consists of an 8-groove belt/pulley system powered through a 77 series PTO driveline. The belt system tension is set at the factory and is designed to maintain its desired tension when stretching.
