Need a powerful, economical dozer with outstanding floatation? You’ll appreciate the D85PXi-18’s 11-liter engine, 14’ 4” straight tilt blade, fuel-efficient automatic transmission and expansive footprint for soft ground conditions. Optional extended wear life undercarriage with 36” wide PLUS (Parallel Link Undercarriage System) rotating bushing track shoes is available.

  • Get new operators up to speed quickly
  • Go from mass ex to finished grading faster than ever
  • Fully integrate 3D design data into your machines
  • Empower operators to work efficiently, pass after pass

Features and benefits

Close the operator skill gap

Machine logic allows the dozer to continuously learn the terrain and make calculated decisions for the next pass. Intelligent Machine Control helps lessen the skill gap between new and experienced operators.

Advanced machine control

In select situations — auto stripping, rough dozing, spreading, advanced finish grading — operators can opt for nearly 100% machine control auto usage. They can even apply automatic control without having a 3D model.

A machine that learns from the operator

Automatic functions give the dozer the ability to learn from operator's blade input, resulting in more adaptability, easier operation and less reliance on operator input.

Outstanding blade response for finish grading

To deliver unparalleled grading performance, iMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly.

Steering System

Palm Command Control System (PCCS) lever controls for all directional movements. Pushing the PCCS lever forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the PCCS lever to left to make a left turn. Tilt it to the right for a right turn.

Hydrostatic Steering System (HSS) is powered by steering planetary units and an independent hydraulic pump and motor. Counterrotation turns are also available. Wet, multiple-disc, pedal-controlled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
