Billed as the first new machine form in decades, the 764 High-Speed Dozer (HSD) is an articulated, rubber-tracked dozer that combines the speed of a grader with the flotation of a crawler dozer. John Deere Construction & Forestry says the machine can grade and push moderate dozing loads at about double the speed of a similarly sized crawler, and it works on soil conditions that are too soft or wet for graders. Its unique undercarriage system combines positive and friction drive for working in slippery conditions and traveling on highways. The machine weighs 32,000 pounds, travels at 18 mph, and is powered by a 200-horsepower Deere 6.8-liter engine. Estimated list price: $338,000. See our video report.
