Improved blade control and fuel consumption are key features of the new D6.The new Cat D6K2 bulldozer, which replaces the D6K, has a stable blade control feature that uses technology to complement the operator’s blade control input to achieve finish grades faster and with reduced operator effort. A wider blade is used with the D6K2, which allows more ground to be covered in one pass, and increases productivity by up to eight percent. The operator can also better control the blade pitch through a new manually adjustable pitch, allowing the settings to closely match the material being handled. The D6 has Eco Modes in both forward and reverse to improve fuel consumption when maximum rpm’s are not required. Another important feature to improve performance and reduce fuel consumption is the hydrostatic drive with traction control, which limits track slip under maximum load.
The new D6 uses the Cat C7.1 ACERT engine, which is turbocharged and after-cooled, and meets Stage IIIA and Tier 4 emission standards. It produces 97 kW (130 hp) at 2,200 rpm. A new fuel system has improved filtration capacity and achieved a higher flow rate for reduced maintenance. Proven K family features that have been retained include a single-lever travel/steering control, a single-lever blade control, a spacious cab and the heavy duty undercarriages. However, a second carrier roller and an eighth track roller have been added for a smoother ride and improved finish grading at higher speeds. The D6K2 can also be fitted with the optional Cat AccuGrade system. Source: www.cat.com
