Komatsu America recently introduced the new D85-18 dozer, suitable for lighter mine-duty bulldozing tasks. It’s powered by a 264-hp Komatsu Tier 4 Final certified diesel—a high-performance, more environmentally friendly engine that burns up to 5% less fuel and costs less to operate. A standard EX track model and a low-ground-pressure PX track model are available to offer customers flotation and weight distribution options that best match their needs.
The Komatsu SAA6D125E-7 engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability. The result is lower fuel consumption with no loss of performance. The D85-18 is equipped with a 9.4-yd3 SIGMADOZER blade for high blading capacity. The SIGMADOZER with standard power pitch improves dozing performance and increases productivity by up to 15% over a conventional Semi-U blade.
The D85-18, equipped with the latest KOMTRAX technology, allows data such as fuel levels, DEF levels, operating hours, location, cautions and maintenance alerts to be relayed to a Web application for analysis. A new Operator Identification System reports key operating information for multiple operators and a new Auto Idle Shutdown function helps reduce idle time.
The unit features a more comfortable working environment, starting with a large cab that is integrated with the ROPS (Roll-Over Protection Structure) for excellent side visibility. The dozer’s cab mounts reduce shocks and vibration, even in adverse conditions, creating an interior cab noise level that’s noticeably quieter. A new high-resolution LCD monitor with pull-down menus enables quick machine adjustments and at-a-glance service diagnostics. A new rear view monitoring system is standard and can be set to synchronize with reverse operation. Also, rear hydraulics are standard on both the EX and PX versions.
