John Deere 850 P-Tier Crawler Dozer
The 850 P-Tier is a 225 hp hydrostatic crawler dozer for earthmoving, finish grading and site preparation. Its dual-path drive controls each track independently for power turns and counter-rotation. The XLT / 146-in PAT reference configuration weighs 48,779 lb and carries a 146 in blade rated at 6.3 cu yd. The manufacturer publishes separate low-ground-pressure and attachment configurations, with different ground pressures, blade widths and operating weights. Grade-control packages extend the machine from manual blade operation to assisted grading.
