Bristling with technology and performance features, the new Cat® D4 is the latest in the range of Next Generation track type tractors to reach Australian shores.
Succeeding the renowned Cat D6K2, the D4 is the latest release to sport the new Cat nomenclature and deliver superior performance with a broad range of features, and options, to help owners extract maximum value.
The Cat D4 (formerly D6K2) has long been a favorite because of its power, precision and optimized balance for smooth grading performance. The latest D4 takes the value up a level with improved sight lines, reduced operating costs, faster steering response and the broadest choice of easy-to-use technology features to improve machine productivity and efficiency.
With the new, clear, size-based machine designations, complexity has been removed for customers by aligning the D4 in the line-up of recently released machines that now includes the D1, D2, D3, D5, D6 and D11.
The D4 is available in Standard or Low Ground Pressure (LGP) dedicated configurations. A Variable Pitch Angle Tilt (VPAT) blade is standard, with an option for a foldable VPAT blade to reduce transport width. This machine is loaded with performance features to ensure work is done quicker, more accurately and with more control. The D4 weighs in at 13,272kg, with a net power of 130 hp (97 kW). D4 LGP has an operating weight of 14,008kg.
Stable Blade works seamlessly with the operator’s blade movements to help produce a smoother surface, is a standard feature. From here, one can simply add to the D4 platform to best suit their needs. For operators needing to create simple designs on-the-go, they can simply select the optional Slope Assist as a GRADE feature that provides basic blade position assistance without a GPS signal.
Moreover, customers can also further up-grade to have the D4 fitted out with a fully integrated, and factory installed, GRADE 3D (GPS) for automatic blade control allowing to easily fulfill a range of complex designs. Interaction is through a large 25cm (10 inch) touch screen display is easy to use – similar to an Android OS smart phone.
There are no longer blade positioning cylinders used like before, but IMU’s mounted on mainframe and blade structures with antennas in cabin roof eliminating any risk of damage. It will also work seamlessly with blade mounted laser or UTS systems. What is new is the ability to benefit with Traction Control and AutoCarry™ with integrated GRADE 3D offering and work seamlessly with Slope Assist. Traction control saves time, fuel and track wear by temporarily reducing track power so the operator can adjust the blade load to limit any track slip. AutoCarry™ automating blade lift to help get more consistent blade loads with each pass. All these features link seamlessly with the hydrostatic transmission to offer the ideal ground speed for the work required.
Technology smart, the D4 allows operators to be ‘best-in-class’ when working to site plans. A key driver in the new D4 was to reduce maintenance costs by having longer service intervals.
Customers can expect up to 7 percent lower maintenance cost as the engine oil/ engine oil filter service interval has been extended. Service intervals have also been extended on the air cleaner and Diesel Exhaust Fluid (DEF) pump filter. LED lights offer up to six times the life of halogen to save on parts cost.
The Cat D4’s Eco modes optimize engine speed, while maintaining ground speed and power, to help customer save fuel in lighter blade load applications like finish grading. Other efficiency features reduce engine speed when idling, or shut the machine down after a specified time also helps to further save fuel and meet idling regulations.
The new cab is key to the customer experience. Inside the cabin, operators will enjoy a new large 25 cm (10 inch) display amongst a raft of features fatigue to not only set-up and overview the machines performance but provide some helpful operating tips.
The cab has integrated Roll Over Protection (ROPS) with 15 per cent more glass area and wider for comfort. Now with a steeper forward hood profile, there is 30 per cent better forward visibility to the blade and worksite.
A new wider air-suspension seat now has more adjustment settings available, additional storage spaces, new USB jack, 12V ports and combines beautifully with the new touch screen monitor allowing operators to not only keep a sharp eye on the machine’s performance, but work shift long with reduced fatigue. This display also acts as extra eyes for a high definition rearview camera display – with back-up lines to help guide the operator.
Interaction with the new D4 is also more seamless. A Cat App helps you manage the machine’s location, hours but also delivers critical maintenance alerts, while Cat Remote Services allows software updates to the machine wirelessly and with remote trouble shoot to perform remote diagnostics.
The D4 can also be ordered with specialized guarding to take on the challenges of Forestry/Land Clearing. In addition to machine protection against impacts and airborne debris, these specialty dozers can be ordered with an impact-resistant cab featuring polycarbonate windows.
