New Hi-Speed Dozer From Deere
March 26, 2008
Twenty-four-inch-wide tracks provide 4,989 square inches of track-on-the-ground for superior flotation.The entire powertrain system works together to distribute power to the tracks for maximum push while avoiding spin. When the machine articulates, the inside and outside track speeds automatically change to improve turning. The hydrostatic transmission also adjusts to deliver the maximum power and speed to the tracks under varying load conditions. Speed can be infinitely controlled from 0 to 18 mph, with four easy-to-use ranges available at the touch of a button. Finish grading can be achieved at speeds around twice that of a comparably sized dozer. An articulation joint gives dozer operators the ultimate in maneuverability, vital when grading around pavement and helpful when navigating side slopes. While turning, the shorter tracks are swept over less ground than longer tracks, extending life and improving performance.
While the 764 HSD is an entirely new machine form, it was developed with reliable, rugged components from other Deere-engineered products with years of experience on the job. The powertrain, hydraulics, blade and C-frame are from John Deere crawlers, while the cab, engine, controls and articulation joint come from Deere 4WD loaders.
The 764’s undercarriage has been designed as a complete unit for maximum life and performance. It excels in soft conditions due to its flotation and provides a smooth ride at higher speeds to produce a high-quality grade. Unlike long steel tracks, there are no track segments to make the blade bounce.
A combination of friction and positive contact ensure the rubber tracks deliver long life. Track tensioning systems also work to extend life. All four tracks are fully, independently suspended and can walk smoothly over uneven or bumpy surfaces. The undercarriage is backed by a 3,000-hour wear assurance program.
