• Engine: The 
  D155AX-7

   is equipped with a Komatsu 

  SAA6D140E-6

   turbocharged diesel engine.

• Net horsepower: It produces 354 horsepower at 1,900 revolutions per minute (RPM).
• Transmission: A TORQFLOW transmission with a lock-up torque converter is standard. This system allows the engine to be connected directly to the transmission when the torque converter is not needed, which reduces power loss and improves fuel economy.
• Emissions: The engine was designed to meet EPA Tier 4 Interim standards by significantly reducing exhaust gas particulate matter (PM) and nitrogen oxide (NOx) compared to previous models.
• Operating weight: The operating weight for a standard machine is approximately 87,100 pounds (39,508 kg). 

• Blade capacity: The 
  D155AX-7

   offered two blade options:

  • SIGMADOZER blade

    : Capacity of 12.3 yd³. This innovative blade is designed to dig and roll material more efficiently than a conventional semi-U blade, which can boost productivity.

  • Full-U blade

    : Larger capacity of 15.6 yd³.

• Undercarriage: The K-bogie oscillating undercarriage is designed to maintain traction and provide a smoother ride over rough terrain. 

• Controls: The dozer features a Palm Command Control System (PCCS) joystick, which provides ergonomic and responsive control for all dozing functions.
• Technology: An in-cab color monitor provides machine data, and Komatsu’s KOMTRAX remote monitoring system sends diagnostic and operational information via satellite.
• Comfort: The cab includes a standard air-suspension, heated seat and is designed to minimize dust and noise for a more comfortable working environment.
