New Komatsu D85EX/PX-

18 Crawler Dozer

The D85EX/PX-18 crawler dozer has an operating weight

ranging between 26.800 kg and 30.190 kg (depending

on machine configuration), it is powered by a Komatsu

SAA6D125E-7 engine that is EU Stage IV emissions certified

and with a net 197 kW (264 HP).

William Groven, Product Manager for dozers says:

“Thanks to its automatic transmission, the

D85EX/PX-18 always operates in its most efficient

working range. This function drastically enhances

the machine’s productivity and lowers its fuel

consumption, making it the most fuel efficient in

its class”.

The Komatsu engine integrates a Komatsu Diesel

Particulate Filter with high passive regeneration rate and

Selective Catalyst Reduction (SCR), to further reduce NOx

emissions using the AdBlue additive.

An advanced electronic control system manages the

airflow rate, fuel injection, combustion parameters and

after treatment functions, ensuring that the engine opti-

mizes performance and reduces emissions.

Komatsu patented SIGMADOZER


The SIGMADOZER blade gives the machine a high blade

capacity of 7,2 m³ and improves dozing performance and

increases productivity by up to 15% over a conventional

Semi-U blade.

The blade features a frontal design concept adopted

for digging and rolling material at the center of the blade.

Soil-holding capacity is increased and digging resistance is

reduced for a smoother flow of material. Larger amounts

of soil can be dozed with less power.

Cab design offers optimal operator


A comfortable and quiet work environment helps opera-

tors maximize productivity. The newly enhanced ROPS

(Roll-Over Protection) cab is large, with excellent side vis-

ibility. Standard features include a high capacity air suspen-

sion heated seat, viscous cab mounts to reduce shocks and

vibrations even in adverse condi-

tions, an upgraded high-resolu-

tion large colour 7” LCD monitor

on which all machine information

is displayed, and a rear view moni-

toring system that can be synchro-

nised with reverse operation.

Komatsu’s ergonomically de-

signed Palm Command Control

System (PCCS) gives operators full

control and offer a relaxed posture

with precision control to eliminate

operator fatigue. Thumb push but-

tons simplify transmission gear


Electronic control

powertrain for

smooth operation

The new dozer uses an electronic control powertrain sys-

tem that significantly improves operation and productivity.

Powerful turns under various work conditions are achieved

with the Hydrostatic Steering System (HSS).

The D85EX/PX-18 is equipped with the latest KOMTRAX

remote monitoring technology. In addition to providing

data such as fuel levels, operating hours, location, cautions

and maintenance alerts, the system has been further en-

hanced to monitor AdBlue levels, KDPF regeneration and

fuel theft.

A new Operator Identification System reports key op-

erating information for multiple operators. The new Auto

Idle Shutdown function helps to improve operating costs

by reducing unnecessary idle time.
