A workhorse for your fleet
Every dozer fleet is built on the workhorses … versatile, powerful machines you rely on day after day, year after year. This dozer was designed from the ground up to fill that role. The Tier 4 Final engine and electronically controlled hydrostatic transmission keep fuel use remarkably low without sacrificing power. A standard parallel link undercarriage system features rotary bushings engineered to extend wear life and lower repair/maintenance costs. In addition to economy and power modes, a high engine rpm H mode helps operators maintain ground speed while operating under heavy loads.
- 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

Hydrostatic transmission
Dual-path, hydrostatic transmission provides infinite speed changes up to 9.0 km/h 5.6 mph. The variable capacity travel motors allow the operator to select the optimum speed to match specific jobs. Travel control lock lever and neutral switch.
| Travel speed (quick shift mode)* | Forward | Reverse |
| 1st | 0-2.1 mph | 0-2.5 mph |
| 2nd | 0-3.5 mph | 0-4.0 mph |

| Travel speed (variable mode) | 0-5.6 mph | 0-5.6 mph |
*Quick shift speeds are adjustable in the monitor.
Final drive
Steering system
PCCS joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it backward reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation. HST eliminates steering clutches and brakes, providing smooth powerful turns. Fully electronic control enables smooth control. The PCCS utilizes shift buttons to increase and decrease speed.
