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
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
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
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
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.
