Model : 850K Crawler Dozer
Engine Net Power : 152 kW (205 hp) at 1,800 rpm
Operating Weight : 19,304–21,775 kg (42,558–48,005 lb.)
Track on Ground : 2,769–3,284 mm (109–129 in.)
Blade Width Range : 3,251–4,267 mm (128–168 in.)
Engine employs field-proven cooled exhaust gas recirculation (EGR), easy-to-maintain high-uptime exhaust filters, and selective catalytic reduction (SCR).
Standard Eco mode automatically adjusts engine power and transmission settings for fuel optimization.
Open-architecture design makes adding the grade-control system simple.
Hinged engine side shields swing open wide and the front grille tilts forward for convenient access to dipsticks, fill tubes, batteries, master electrical shutoff, the backside of the cooler, and engine, transmission, and hydraulic filters.
Maximum Life undercarriage features SC-2™-coated bushings, larger components and stronger seals for longer wear life compared to basic undercarriage.
Grade-control system is fully integrated into the machine cabin, structures, and software – delivering precise grading performance while eliminating vulnerable external masts and cables.
Auto SmartGrade automatically raises the blade when heavier loads are encountered during rough grading to prevent stalling and track slip, enabling the machine to be used in all phases of grading.
Machine dimensions are preloaded into the grade-control monitor, reducing the time needed to calibrate to about 30 minutes.
