New Komatsu D71PXi-24 Bulldozer for Sale How do you make one of the industry’s most capable, dependable dozers even better? Make it smart. The industry’s newest slant-nosed, intelligent HST dozer features the latest iMC 2.0 capabilities, and patent-pending proactive dozing control with the ability to operate automatically 100% of the time.
Learns as it works: With proactive dozing control, even your less experienced operators can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass. Can improve productivity by up to 60% versus previous generation. Spreads fill material automatically: Lift layer control automatically lets your operators spread fill from existing terrain with the press of a button. The dozer measures the terrain it tracks over and uses the data it gathers to plan the next pass. Attain up to double your production and achieve consistent layers for compaction quality. Levels material even during rough dozing: Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80%. Quick surface creation: Operators can create a temporary design surface with the press of a button. Combined with other iMC 2.0 functions, your crew can begin stripping or spreading using automated input while waiting for the finish grade model. Close the operator skill gap: Machine logic allows the dozer to continuously learn the terrain and make calculated decisions for the next pass. Intelligent Machine Control helps lessen the skill gap between new and experienced operators. Advanced machine control: In select situations — auto stripping, rough dozing, spreading, advanced finish grading — operators can opt for nearly 100% machine control auto usage. They can even apply automatic control without having a 3D model. A machine that learns from the operator: Automatic functions give the dozer the ability to learn from operator's blade input, resulting in more adaptability, easier operation and less reliance on operator input. Outstanding blade response for finish grading: To deliver unparalleled grading performance, iMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly. D71 intelligent Machine ControlHow do you make one of the industry’s most capable, dependable dozers even better? Make it smart. The industry’s newest slant-nosed, intelligent HST dozer features the latest iMC 2.0 capabilities, and patent-pending proactive dozing control with the ability to operate automatically 100% of the time. Features: OUTSTANDING VISIBILITY FOR YOUR OPERATORSOutstanding visibility to the cutting edges and excellent balance and maneuverability with a super-slant nose cab-forward design. SMOOTH SHIFTING AND CONTROLSmooth, powerful turns with hydrostatic steering. Fully electronic control provides complete automatic shifting and allows for Quick-Shift or variable speed selection. CHOOSE THE RIGHT MODE FOR THE JOBIn P mode, the engine outputs its full power to help your operator perform heavy-load work. It automatically increases engine speed for maximum power when load increases. H mode increases engine high idle speed, suitable for power-intensive work. VERSATILE AND PRODUCTIVE ADJUSTABLE BLADEFlexibility to adapt to various situations and the ability to be efficient and productive regardless of the terrain with a versatile 6-way PAT (power angle tilt) blade pitch system. EASY-ACCESS MAINTENANCE FEATURESEasy access to the radiator, oil cooler and charge air cooler with swing-up assisted lift system. Hydraulic fan reverses for clearing objects restricting air flow. Rear-mounted single-plane cooling system swings up for fast service. LONG-LASTING UNDERCARRIAGEDesigned to wear evenly so the machine provides close to 100% usage of undercarriage components, Komatsu PLUS undercarriage lowers undercarriage maintenance costs by up to 40% over a conventional undercarriage. Strengthened rollers and links increase wear life up to two times. READY FOR LOW GROUND PRESSURE NEEDSTo provide your operation with even more versatility and adaptability, the D71 is available with an optional 36-inch wide shoe for low ground pressure applications. COMFORTABLE, ERGONOMIC CONTROLSDesigned for your operator’s comfort and ease of use, the ergonomic, low-effort palm command control system (PCCS) joystick controls all directional movements, including machine travel speed and counter-rotation. BLUETOOTH/USB-COMPATIBLE RADIOTo help maximize operator comfort and connectivity, the D71 comes with standard Bluetooth AM/FM radio and additional AUX and USB connection capability. |
