Komatsu introduce new GD675-7
motor grader
industry‐exclusive dual‐mode transmission (8 forward, 4
reverse) allows operators to benefit from the high travel
speed and the reduced fuel consumption provided by a direct
drive, and from the increased tractive effort and control of a
torque converter.
The powershift transmission, designed and built
specifically for Komatsu graders, provides on‐the‐go full
power shifting, as well as inching capability and automatic
shifting in the higher ranges. A full locking differential offers
the required traction, even in the most severe operating
conditions.
A new transmission shift lever, with a finger‐operated
Forward–Neutral–Reverse switch, simplifies operations
and significantly reduces the amount of hand movement
required, while the new inching pedal allows precise control
of the machine.
According to Komatsu, the slightly smaller but ‘right size’
steering wheel improves visibility and operator room in the
cab and is convenient for long ‘blade‐up and roading’ trips. A
new steering lever lets the operator keep both hands on the
low‐effort work equipment levers and make small steering
adjustments, while operating, without needing to turn the
steering wheel.
In addition, the new multi‐position adjustable armrests
and LH/RH consoles can be precisely matched to the
operator’s preferences thanks to a powered raise/lower
function and mechanical fore/aft adjustments.
Marubeni-Komatsu has announced the introduction of the
new Komatsu GD675‐7 motor grader, featuring a powerful
and efficient EU Stage V emission‐certified engine and
‘heavy‐duty’ after-treatment system that combines a
Komatsu diesel particulate filter (KDPF) with a selective
catalytic reduction (SCR) system.
Along with the new EU Stage V engine, strong
development focus was put on operator comfort. The
complete redesign of the controls to a fingertip system
reduces operator arm movement by more than 90%. Thanks
to this, and combined with new transmission controls,
new stop‐at‐centre articulation and much better visibility,
operator stress and strain is greatly reduced.
For optimal fuel savings, a two‐mode, three‐stage,
variable horsepower control (VHPC) allows the selection of
the appropriate mode, Economy or Power, to match operating
parameters to the application. After-treatment components
were designed together with the engine for efficiency and
long life. The KDPF is now combined with a new integrated
Komatsu SCR system using AdBlue, to further reduce
NOx emissions. More than 98% of KDPF regeneration is
performed passively, with no action required of the operator
and no interference in machine operation.
The Komatsu auto idle shutdown function automatically
turns off the engine after it idles for a set period of time,
helping to lower operating costs and reducing unnecessary
fuel consumption and exhaust emissions. Komatsu’s
