Equipment Overview

The John Deere 850 is a medium dozer built for site development, road building, and mass excavation, part of Deere’s L-Series crawler dozer range and the current-generation dozer sold in the Australian market. It has 168 kW (225 hp) of net power and an operating weight of 21,581–23,299 kg depending on track and blade configuration, suited to heavy civil earthworks and grading, with a power-angle-tilt blade available up to 172 in (4,359 mm) wide — the widest in its class.

Power comes from the John Deere PowerTech PSS 6090 9.0-litre engine, which meets EPA Final Tier 4/EU Stage IV emission standards. A dual-path hydrostatic transmission gives each track its own independent pump and motor, with single-lever steering and counter-rotation for full-power turns, and Eco mode automatically adjusts engine power and transmission settings to load. A rear-mounted, three-shank parallelogram ripper with hydraulic pitch adjustment is available for scarifying compacted ground.
