No blade mounted GNSS antenna(s), cables to worry about damaging with cab top GNSS antenna. Reduced risk of theft due to low visibility as viewed from ground level.
Robust stroke sensing hydraulic cylinders employ proven Komatsu sensor technologies for accurate finish grade performance. Stroke sensing angle cylinder allows machine control system to know the angle of the blade.
Chassis mounted IMU+ and intelligent logic enables accurate grading performance without blade mounted sensors.
The Komatsu SAA6D140E-7 engine is EPA Tier 4 Final emissions certified and provides exceptional performance while reducing fuel consumption. Based on Komatsu proprietary technologies developed over many years, this new diesel engine reduces nitrogen oxides (NOx) by more than 80% when compared to Tier 4 interim levels. Through the in-house development and production of engines, electronics, and hydraulic components, Komatsu has achieved great advancements in technology, providing high levels of performance and efficiency in virtually all applications.
This new system combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR). The SCR NOx reduction system injects the correct amount of DEF at the proper rate, thereby decomposing NOx into non-toxic water (H2O) and nitrogen gas (N2).
New D155AXi-8 has achieved both high levels of productivity and fuel economy through usage of SIGMADOZER and automatic transmission with lockup torque converter.
The ripper control lever is new, ergonomic and incorporates an auto-return function that will automatically raise the ripper so the operator is less fatigued at the end of the day. The function starts when travel lever is moved to reverse position.
Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.

Komatsu's automatic TORQFLOW transmission consists
of a water-cooled, 3-element, 1-stage, 1-phase, torque
converter with lockup clutch, and a planetary gear, multipledisc
clutch transmission which is hydraulically actuated and
force-lubricated for optimum heat dissipation. Equipped with
gearshift lock lever and neutral safety switch.

Double-reduction, spur and planetary final drives increase tractive effort. Segmented sprockets are bolt-on for easy in-the-field replacement.
PCCS lever controls for all directional movements. Pushing the PCCS
lever forward results in forward machine travel, while pulling it rearward
reverses the machine. Simply tilt the PCCS lever to the left to make a
left turn. Tilt it to the right for a right turn.
Hydrostatic steering system (HSS) is powered by steering planetary
units and an independent hydraulic pump and motor. Counter-rotation
turns are also available. Wet, multiple-disc, pedal-controlled service
brakes are spring-actuated and hydraulically released. Gearshift lock
lever also applies parking brakes.
