2024 Komatsu Dozers D39EXi-24
Powerful, versatile and yes, nimbleIf you want a dozer that’s equally at home performing heavy site prep and accurate fine work, this model is an excellent choice. Powered by a fuel efficient, environmentally friendly EPA Tier 4 Final certified engine, it offers your operators a quiet, comfortable cab that provides unrivaled blade visibility. It’s engineered to get jobs done quickly and accurately with its outstanding blade response, fast work equipment speed, an additional “fast-blade mode” that boosts blade speed for high-speed grading, and surprising maneuverability via full power to both tracks during turns or counter rotation steering.
Features may include:
Learns as it works- With proactive dozing control, even your less experienced operators can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass. Can improve productivity by up to 60% versus previous generation.
- Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80%.
- 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.
- 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.
- 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.

Transmission
Dual-path, hydrostatic transmission provides infinite speed changes up to 5.3 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: 1st: 0–2.1 mph / 2nd: 0–3.5 mph / Travel speed (variable mode): 0–5.3 mph | Travel speed (quick shift mode)* Reverse: 1st: 0–2.5 mph / 2nd: 0–4.0 mph / Travel speed (variable mode): 0–5.3 mph
Drive System
Final drive: In-shoe mounted, axial-piston-type travel motors, with integrated two-stage planetary gear reduction. Compact, in-shoe mount reduces risk of damage by debris. Bolt-on sprocket ring with triple labyrinth seal design.
Steering
Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it back 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. Hydrostatic Transmission (HST) provides smooth, powerful turns. Fully electronic control enables smooth control that can be adjusted in the monitor. The PCCS utilizes shift buttons to increase and decrease speed.
