Deere announced that it would start selling the 764 High-Speed Dozer (HSD) in April with significant changes compared to the prototype HSD that debuted at Conexpo in March 2008. The new machine form – a high-flotation dozer/grader/towing tractor with top speed of 18 miles per hour – now has a rear axle that oscillates on a center pivot instead of a rear suspension. Track modules, developed with Camoplast, are upgraded with cast track frames (frames on the 2008 prototype were fabricated). Production HSDs are upgraded with the same cab as Deere’s new K-Series loaders. The 764 HSD weighs 34,000 pounds and is powered by a Tier-3 PowerTech Plus 6.8-liter engine rated at 200 horsepower through a hydrostatic drive train.
