Adding to its lineup of wood-waste processing equipment, Morbark combines heavy-duty construction and new technology in the 1300B tracked tub grinder – “the definitive mobile tub grinder.” With the undercarriage of a Caterpillar 330L excavator as a base, the 1300B uses Morbark’s Iqan feed system that automatically adjusts feed rates, pressures and feed-wheel positions to optimize production and engine efficiency, further enhanced by the use of hydraulic augers and a laser-cut hammermill. In addition, optional features allow this machine to be customized to individual needs.
