Intelligent Machine Control Innovative Intelligent Machine Control The D61i-24 comes with a fully fac- tory installed 3D Global Navigation Satellite System (GNSS) Machine Control system. Add-on components for machine control typically mount- ed on the blade are now replaced with a factory installed cab top GNSS antenna, an enhanced inertial measuring unit (IMU+), and with stroke sensing hydraulic cylinders. This integrated sensor package is robust and accurate. It eliminates the daily hassles of installing and removing antennas and cables from the blade, and the wear associated with it. Automatic dozing from start to finish While high-precision finish grad- ing can be achieved by dozers with a conventional control system, the D61i-24 can also perform rough doz- ing in automatic mode. When rough dozing, the fully automatic blade control monitors blade load and adjusts blade elevation, to minimise track slip and perform high-efficiency dozing. Blade control adjusts to pro- vide finish grade performance with high-level precision. 4

Improved efficiency The fully automatic modes drastically improve efficiency of dozer opera- tions. Intelligent machine control technology helps even less experi- enced operators perform top quality work. As-built surface track mapping Cab top GNSS antenna provides accurate “as-built” surface data by measuring actual elevations. Pro- gress can be measured in real time with operator-selectable settings. 7

VGT SCR Komatsu EU Stage V The Komatsu EU Stage V engine is productive, dependable and efficient. Cooled EGR With ultra-low emissions, it provides a lesser 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 Re- duction (SCR). The SCR system in- jects the correct amount of AdBlue® KDPF at the proper rate to break down NOx into water (H2O) and nontoxic nitrogen gas (N2). NOx emissions are reduced by 80% vs. EU Stage IIIB engines. Exhaust Gas Recirculation (EGR) Komatsu Closed Crankcase Ventilation Cooled EGR is a technology well-proven (KCCV) in current Komatsu engines. The increased Crankcase emissions (blow-by gas) are capacity of the EGR cooler now ensures passed through a CCV filter.

Tough and Reliable Low-drive “PLUS” undercarriage Komatsu’s low-drive Parallel Link Undercarriage System (PLUS) is extraordinarily tough, with excellent grading performance and stability. It features PLUS link assemblies, a highly reliable floating bush- ing concept, substantial track link height, superior oil seals and track guards that maximise undercarriage durability. For easier servicing, the equaliser bar’s centre pin is remotely greased. The segmented sprockets are notched to considerably improve the evacuation of mud and further increase the PLUS undercarriage lifetime. EXi undercarriage The EXi undercarriage has been specially designed for working on hard ground. The small to medium- width shoes and PLUS link assembly ensure a large contact area between the machine and the ground for maximum stability, grading perfor- mance and undercarriage lifetime. PXi undercarriage The PXi undercarriage is ideal for working on soft surfaces.
