Unmatched Visibility and Safety The best view A super slant nose gives the D37EX/PX-22 the best visibility of any dozers on the market. This unique feature dramatically increases efciency and jobsite safety, with operators now always having full view of both the blade and the ripper and of objects close to them. The new cab-forward design, with integrated ROPS/FOPS and large glass windows, provides more room and places the operator closer to the blade, further improving visibility and comfort. Safe and easy access For a safer entry and exit - and maximum operator protection, the D37EX/PX-22...

High Productivity & Low Fuel Consumption A clean, powerful engine A powerful yet fuel-efcient engine makes the D37EX/PX-22 an outstanding performer both for dozing and ripping. This 67,7 kW / 90,8 HP ecot3 engine features a new combustion chamber design with optimised ignition and combustion timing. The operating pressure of the new common rail system was increased for improved injection and fuel efciency. The air-to-air intercooler reduces the temperature of the compressed air supplied by the turbo charger to the cylinders, and further improves fuel consumption. Hydrostatic transmission...

Efcient hydrostatic engine cooling fan The cooling fan always runs at the lowest convenient speed. Rotation and velocity are electronically adjusted based on the temperature of the engine coolant and hydraulic oil. This reduces fuel consumption and operating noise levels, and requires less horsepower than a belt-driven fan. For extra efciency, the fan also has a large air outlet surface, and the complete inlet area is protected by a ne grid, to prevent small particles from entering the fan area. 7

First-Class Operator Comfort A smooth ride and lower noise levels The cab on the D37EX/PX-22 was moved forward, and operators now sit closer to the centre of gravity of the machine. With the ripper still easily within eyeshot, they enjoy the best view of the blade, the lowest vibration levels and the highest stability of any dozer on the market. Silicon oil lled cab damper mounts isolate the operator compartment from the machine body and suppress vibrations, providing a quiet, comfortable operating environment. A new unique location for the radiator - at the rear of the machine - and the...

High Reliability and Durability Low drive undercarriage Modular design Komatsu’s low-drive undercarriage design is extraordinarily tough and offers excellent grading performance and stability. It features heavy-duty link assemblies with large-diameter bushings, substantial track link height and superior oil seals to maximise undercarriage durability and lifetime. The D37EX/PX-22 was designed and manufactured to have low maintenance costs and a long lifetime. This was achieved mainly by reducing component complexity and with a strong modular design. EX undercarriage Komatsu’s monocoque track...

Easy Maintenance Simple and convenient service Self-diagnostic monitor Protected hydraulic piping Well located service doors allow convenient and safer ground access to daily service points. With the radiator located at the rear of the machine, engine fuel and oil lters can be easily accessed from the front of the engine compartment. Remote grease points facilitate lubrication of the C-frame pivots and angle cylinder bearing. The multi-function monitor panel displays the running time, engine revs, fuel level and water coolant temperature in real time. It also provides the operator with...

Reversible swing-up fan The D37EX/PX-22 includes a swing-up fan with a gas strut-assisted lift locking system to provide easy access to the radiator, oil cooler, and charge air cooler. The operator can switch the hydraulic fan to “cleaning” mode so that it rotates in reverse at full speed to clean the radiators, reducing maintenance costs and improving fuel efciency. 13
