he new 178 Caterpillar D6N bulldozer is said to combine proven reliability and durability with greater fuel efficiency, enhanced productivity, finish grading performance and operator comfort.

aid to be perfect for fine grading applications, the D6N has a Cat C6.6 ACERT engine meeting U.S. 1293 Environmental Protection Agency (EPA) Tier 4 Interim, European Union Stage IIIB and Japan MLIT Step 4 emissions standards. The Cat Clean Emission Module, which incorporates a Diesel Oxidation Catalyst (DOC), a Diesel Particulate Filter (DPF) and the Cat Regeneration System, is said to function automatically without interrupting the machine’s working cycle.

Greater fuel efficiency is achieved with the D6N through its new Auto Engine Idle Shutdown timer, an Auto Engine Speed Control and an on-demand viscous clutch for the cooling fan. In addition, Eco Modes can be activated in Forward or Forward/Reverse settings, said to provide the potential to substantially reduce fuel consumption even further, thus lowering owning and operating costs.

An Auto Shift/Auto Kick-Down function is said by Cat to allow pre-selection of forward and reverse speed settings. It is also said to increase production, fuel efficiency and ease of operation.

The D6N features a proven differential steering controller found in other Cat bulldozer models.  The steering tiller places all transmission functions in one hand, allowing the operator to easily select forward-neutral-reverse functions, speed recall and ground speed adjustment – the latter using a thumb roller wheel incorporated into the steering controller. The design also features solid grip support in harsh applications.
Cat says the new bulldozer has improved ergonomics, including the introduction of new electro-hydraulic controls and updated easy-to-read dashboard displays providing all the machine information within easy reach of the operator.

The D6N is described as Grade Control ready, with integrated harnesses incorporated into the machine during assembly. This is said to allow for easy dealer installation of an AccuGrade machine control and guidance system when the machine is purchased or later as business requirements change.

This new bulldozer model is also fitted with Cat Product Link, which allows remote monitoring of equipment to improve overall fleet-management effectiveness.
