Features

The operator seat has adjustable lumbar support, tilt and an electric heater. It is easy to adjust to the operator's shape. Also, the standard seat heat makes it possible to work comfortably in the winter.
 

Planned maintenance and daily checks are the only way to ensure long service life from equipment. That’s why Komatsu designed the D61EXi-24 with conveniently located maintenance points to make necessary inspec-tions and maintenance quick and easy.
 

The D61EXi-24 utilizes a swing-up fan with a gas strut-assisted lift system to provide easy access to the (side-by-side) radiator, oil cooler and charge air cooler. The hydraulic fan has a cleaning mode which can be used for periodic cooler cleaning.
 

The electronic controlled, palm commanded joystick provides precise blade control. New blade angling switch operation provides easier and predictable blade control.
 

This new system combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR). The SCR NOx reduction system injects the correct amount of DEF at the proper rate, transforming NOx into non-toxic water (H2O) and nitrogen gas (N2).
 

The system recirculates a portion of exhaust gas into the air intake and lowers combustion temperatures, thereby reducing NOx emissions. EGR gas flow has been decreased for Tier 4 Final with the addition of SCR technology. The system achieves a dynamic reduction of NOx, while helping reduce fuel consumption below Tier 4 Interim levels.
 

The system is designed to achieve an optimal injection of high-pressure fuel by means of computerized control, providing close-to- complete combustion to reduce PM emissions. The system uses high pressure injection, thereby reducing both PM emissions and fuel consumption over the entire range of engine operating conditions. The Tier 4 Final engine has advanced fuel injection timing for reduced fuel consumption and lower soot levels.
 

Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.
 

The KVGT system features proven Komatsu design hydraulic technology for variable control of air-flow and supplies optimal air according to load conditions. It provides better exhaust temperature management. The Tier 4 final version has an improved propeller design for increased performance.
 

Various meters, gauges and warning functions are centrally arranged on the multi-monitor. The monitor simplifies start-up inspection and promptly warns the operator with a lamp and buzzer if any abnormalities occur. In addition, countermeasures are indicated in 4 levels to help prevent major machine problems. Replacement times for required PM services are also indicated.
 

Komatsu's new PLUS provides less downtime, plus longer wear with up to 40% lower undercarriage maintenance costs. Rotating bushings eliminate the cost and downtime for bushing turns, and strengthened rollers and links increase wear life up to two times. With PLUS, individual links can be replaced with common track tools.
 

A power angle power tilt dozer blade with adjustable blade pitch system is available. This blade is available for the D61EXi-24 machines. The hydraulic blade tilt, angling function (and manually adjustable blade pitch) expand versatility and productivity in a variety of applications.
 

Robust stroke sensing hydraulic cylinders employ proven Komatsu sensor technologies for accurate finish grade performance. Stroke sensing angle cylinder allows machine control system to know the angle of the blade.
 

P mode is the mode designed for powerful operation and maximum production. E mode is designed for general dozing applications providing adequate speed and power while  saving energy. For fuel reduction and energy saving, the monitor panel allows the operator to easily switch the working mode, depending on the work at hand.
 
P mode (Power mode)
With P mode, the engine outputs its full power, allowing the machine to perform the work requiring large production, heavy-loads and uphill work.
 
E mode (Economy mode)
With E mode, the engine outputs enough power for the work without delivering unnecessary power. This mode enables energy saving operation and is ideal on hard or rough surfaces that often cause shoe slip and work not requiring as much power, such as downhill dozing, leveling and light-load work.
 
H mode (high engine idle speed mode)
This setting allows subtle changes in load to be detected, which is tailor-made for power-intensive work. Compared to P mode, the engine high-idle speed is higher in H mode.
