Blade

At 172 inches, the Power-Angle-Tilt (PAT) blade is the widest in its class — helping to increase productivity, especially when grading.

Outside dozer (OSD) blade is available in extra-long-track (XLT), wide-long-track (WLT), and low-ground-pressure (LGP) track configurations.

Three-position adjustable mechanical-angle blade lets you put this dozer to work in a variety of unique applications including backfilling, rough grading, and general earthmoving.

Simple Maintenance

Enlarged service doors provide quick access to conveniently located checkpoints and filters.

Extended service intervals help minimize maintenance and expense.

Standard hydraulic reversing fan automatically back-blows the cooler cores at preset intervals. Or simply press a button when conditions demand more frequent cleaning.

Cab and Controls

An angled seat allows for a clear view to the ripper.

Ergonomic joysticks, ample storage, and an automatic temperature control option also provides daylong comfort and convenience.

Engine

This EPA Final Tier 4 (FT4)/EU Stage IV-certified engine delivers a winning combination of performance, fluid efficiency, and reliability.

Grade-Control Ready

SmartGrade™, John Deere’s mastless machine-control solution, is fully integrated, easy to set up and run, and available from the factory.

With standard electrohydraulic (EH) controls and an “open-architecture” design, the 850L makes it easy to add the grade-control system of your choice, whether it’s Topcon, Leica, or Trimble.
