Rolling Meadows, IL— Komatsu America Corp. today introduced its new line of D61-23 crawler dozers that were developed with extensive customer input. Utilizing this invaluable customer feedback, Komatsu America has produced a crawler dozer that is smarter, more productive, more owner- and operator-focused and that offers lower owning and operating costs. Using its popular D51-22 as a design starting point, Komatsu refined the dozer design to meet EPA Tier 4 Interim regulations while providing more owner- and operator-focused features, all bundled in a larger 130 to 160 HP package that pushes productivity and efficiency to new levels.
New longer track-on-ground standard (EX) and low ground pressure (PX) models are available to offer customers flotation and weight distribution options that best match their applications. Operating weight ranges from 39,099 lbs. to 41,138 lbs. depending on the configuration. The new models push with a net 168 HP at 2200 rpm.
Developed as a versatile multi-tool, the D61-23 is designed for a wide variety of applications, including land clearing, grading, forestry and site work. A full guarding package, hydraulic winch and other attachments are available for easy customization to meet specific customer requirements.
The D61-23 crawler dozer is equipped with the latest KOMTRAXÒ technology, which is fully integrated with Komatsu’s Tier 4 technology and sends machine operating information to a secure website utilizing wireless technology. Hour meter, location, cautions, load ratio, fuel consumption and maintenance alerts – to name a few of its features – are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft (compared to machines not KOMTRAX-equipped), allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity.
Special features of these new crawler dozers include:
Built upon proven Komatsu Tier 3 technology, the Tier 4 Interim SAA6D107E-2 engine provides the same horsepower as its predecessor while lowering fuel consumption by up to 10%. Komatsu’s Tier 4 Interim engine platform uses an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability.
The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation but will keep the operator aware of its status.
