Higher Efficiency
The new dozer retains Komatsu’s
proven hydrostatic drive line
which supplies high drawbar
pull when needed with precision
control when fine grading.
The operator can select either
‘quick-shift’ or ‘variable speed’ to
match the ground condition.
The cab has been moved for-
ward, putting the operator closer
to the centre of gravity of the ma-
chine. This gives a better view to the ripper and
improved visibility to the dozer.
The ROPS/FOPS cab is to a new design with larg-
er, tinted windows and improved sealing to keep
dust, moisture and noise outside.
The operator’s seat is a comfortable, heavy-duty,
air suspension style, complete with headrest, The
result is 79 dB(A) noise level to the operator (LpA)
and hand/arm vibration <2.5 m/s² and body vibra-
tion <0.5 m/s².
Travel speed is up to 9.00 km/h in both for-
ward and reverse gears. Dozer blade ranges from
3,250 mm x 1,195 mm with 3.4 m³ PAT blade on the
EX model up to 3,860 mm x 1,155 mm with 3.8 m³
PAT blade PXI)
A Second Dozer Launch
Komatsu has also introduced the D37EXi/PXi-23
dozer to the European market which is configured
to the same degree with Komatsu’s latest intelligent
Machine Control technology, enabling both finish
grading and rough dozing in full automatic blade
control mode.
This dozers meets EU Stage IIIB regulations us-
ing smart engine technology, with operator-specific
features bundled into a compact 89 horsepower
package.
Operating weights range from 8,640 kg to
8,940 kg depending on the configuration and mod-
el. At 2200 rpm, the D37EXi/PXi-23 pushes with a
net 66,1 kW (89 HP).
Both dozers come equipped with the Komatsu
Diesel Oxidation Catalyst (KDOC), which has an in-
tegrated design that does not interfere with daily
operation.
This smart
and
simpli-
fied system
removes soot
using 100%
“passive regeneration” with-
out the need for a Diesel Particulate Filter (DPF).
The KDOC has no scheduled replacement inter-
val and is designed for long life with no required
maintenance. For owners, this means lower own-
ing and operating costs due to less complexity and
seamless operation for the operator.
Excellent blade visibility and ride
The steeply sloped engine hood and forward cab
design provide more room for operators while
moving themcloser to the blade, for improved blade
visibility, ride quality, enhanced grading ability and
overall comfort.
Viscous cab damper mounts suppress noise and
vibration when travelling over rough terrain making
these new models quieter than their predecessors.
For a quieter working environment, the interior cab
decibel level has been decreased to 77 dB(A).
Durable and productive power
angle tilt (PAT) blade
An efficiently-designed PAT blade with a highly
durable box structure and good curvature, rolls
material efficiently and improves productivity.
Standard adjustable blade pitch allows the op-
erator to adjust the aggressiveness of the cutting
edge for varying applications. The hydraulic blade
angle toggle switch improves ease of blade opera-
tion.
