Intelligent Machine Control 2.0 Intelligent Machine Control (iMC) 2.0 With the D71EXi/PXi-24, you benefit from second-generation intelligent Machine Control (iMC 2.0). It continuously scans the jobsite and uses the data to plan the next pass. This leads to a huge increase in your productivity and accuracy with just the press of a button. The D71EXi/PXi-24 can work in automation modes almost continuously, is furnished with ergonomic one-touch controls, and allows any operator to work like a pro. Quick surface creation You can create a temporary design surface by just pressing a button. Begin stripping...

D71EXi/PXi-24 Lift layer control This function measures the terrain your machine tracks over and uses that data to plan the next pass. Automatic blade control will follow the finish surface and eliminate excess fill, potentially doubling your production. Target surface for first layer Ground surface Proactive dozing control You can use automatic blade control from rough grading to finish grading work. Proactive dozing control understands the terrain in the path of each cut, maximises the blade load throughout the pass, regardless of the terrain ahead, and helps to achieve the same productivity...

Proactive dozing control • Up to 60% more productive* • Applications: stripping topsoil, highproduction dozing • Uses data from previous pass to plan the next pass • Automatic cut/strip from existing terrain • Helps new operators perform like an experienced one Tilt steering control • Up to 80% less operator input required** • Automatically tilts the blade to maintain straight travel while rough dozing • Maintains consistent power to the ground and track Lift layer control • • • • Lift time reduced by up to 50%** Applications: lifting, compaction quality control Maintain precise lift thickness...

Smart Construction Remote is an optional software solution that enables to remotely send and update design plans even when the machine is offline. It also supports your operators remotely with shared screen control. Does an operator have an issue? Spare yourself that trip to the machine and resolve the problem from home, your office, or another jobsite. Smart Construction Remote works on our very own Komatsu iMC machines and several After Market GNSS systems powered by Windows and Android.

Highly efficient hydrostatic drive line The hydrostatic drive line is a key factor in the performance of the D71EXi/PXi-24 dozer. It supplies high drawbar pull when needed and a highly fuel efficient drive line for grading and precision work. With a choice between two operating modes, the operator can select either “quick shift” or “variable speed” to match a complete range of applications in the most economic and easy way. Hydrostatic transmission (HST) control system The unique, Komatsu-designed hydrostatic transmission controller monitors the engine output and working equipment or travel load....

Powerful and environmentally friendly Komatsu EU Stage V The Komatsu EU Stage V engine is productive, dependable and efficient. With ultra-low emissions, it provides a lower environmental impact and a superior performance to help reduce operating costs and lets the operator work in complete peace of mind. Heavy-duty aftertreatment The aftertreatment system combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR). The SCR injects the correct amount of AdBlue® into the system at the proper rate to break down NOx into water (H2O) and non-toxic nitrogen gas (N2)....

First-class comfort Operator comfort is essential for safe and productive work. The cab on the D71EXi/PXi-24 is quiet and comfortable, an ideal environment to concentrate on the job. Its hexagonal design and large tinted glass windows offer excellent panoramic visibility. The high capacity climate control system pressurises the cab to keep dust out. A high quality sound-absorbent lining covers the interior to minimise noise levels for the operator. The operator can connect his mobile device to the machine’s Bluetooth® radio. A super slant nose gives the D71EXi/PXi-24 the best visibility of any...

Control features Large TFT colour multifunctional monitor A large user-friendly colour monitor enables safe, accurate and smooth work. It provides on-hand data to continuously improve productivity and fuel consumption. Multilingual and with all essential information available at a glance, it features simple and easy to operate switches and multifunction keys that provide the operator with fingertip access to a wide range of functions and operating information. Automatic speed change Komatsu HST controller always changes the travel speed automatically, depending on load or ground conditions, and...

An evolutionary interface Helpful information is now easier than ever to find and understand with the upgraded monitor interface. An optimal main screen for the ongoing work can be selected simply by pressing the F3 key. Lower operating costs Widescreen monitor Adjustable idle shutdown automatically turns off the engine after it idles for a set period of time. In addition, the new auto-deceleration function automatically lowers engine speed, when levers are in neutral for a set time. Eco guidance records and fuel consumption history can be displayed on the monitor. Komatsu ICT contributes to...
