  • Feature
  • Parameter
New Power and Economy modes: Full power when you need it and Economy mode to save fuel when you don't. New engine and hydrostatic pump control technology improves operational efficiency and lowers fuel consumption. SAA4D95LE-6 variable flow turbocharged and aftercooled 3.26 liter diesel engine provides excellent fuel economy. This engine is EPA Tier 4 Interim and EU Stage 3B emissions certified. Variable Flow Turbocharger uses a simple valve to provide optimum air flow under all speed and load conditions. Komatsu Diesel Oxidation Catalyst reduces particulate matter using passive regeneration 100% of the time. No active or manual regeneration is required. Rear view monitoring system (standard) Advanced diagnostic system continuously monitors machine operation and vital systems to identify machine issues and assist with troubleshooting. Single pedal can act as either brake or Decelerator Improved Cooling System ■ Electronically controlled hydraulically driven fan is manually reversible ■ Gas assisted lift cylinders on radiator cover opens for easy cleaning ■ Side-by-side coolers with increased cooling capacity Integrated ROPS cab features: ■ Large, quiet, and pressurized cab ■ Excellent visibility with integrated ROPS structure ■ New heated air-ride seat with 15% higher capacity (standard) ■ Standard aux jack and (2) 12V power convertors Improved durability ■ Heavy-plate steel used for nose and tanks ■ Dozer frame with full steel castings ■ Komatsu designed and manufactured components Self-adjusting idler support provides constant and even idler tension, reducing vibration and increasing undercarriage life. Power Angle Tilt (PAT) dozer with manually adjustable blade pitch increases productivity in a variety of applications. ■ Three mounting locations for grade control masts Complete operator blade control ■ Palm Command Control System (PCCS) ■ Electronic Proportional Control (EPC) ■ Adjustable Quick shift and Variable shift modes ■ New blade angle switch ■ Normal and Fine blade controls ■ Multiple Operator memory storage New more efficient HST with electronic control ■ Customizable Quick shift (3 speed) settings for the operator ■ Variable speed selection (20 speeds) ■ Low speed matching technology (larger displacement pumps/efficient engine speed) ■ Up to 20%* reduced fuel consumption in E mode and 10%* in P mode. Large color monitor ■ Easy-to-read and use large 7" high-resolution multi-color monitor ■ ECO guidance ■ On-board diagnostics KOMTRAX® equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more. * Compared to D39-22 model
