If you need the biggest, badest, highest production Truck Mounted Grinder, look no further than the TMG 6300. Built on a 66,000 GVW chassis. Equipped with four larger, heavier grinder housings, (two left, two right). A massive 300 horse power, 6 cyclinder, turbo charged, John Deere diesel engine. This model does NOT come with a dust collector. A matching Road Vac RV 4140 dust collector tailer is available. By utilizing a seperate towable dust collector, debris capacity is increased greatly.
