The Cat D4 (formerly D6K2) dozer 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 and the broadest choice of easy-to-use technology features to help get the most from the bulldozer.
The D4 weighs in at 29,259 lbs. (13,272 kg), with a net power of 130 hp (97 kW). D4 LGP has an operating weight of 30,882 lbs. (14,008 kg).
A lower sloping hood line provides up to 30 percent better visibility to the area in front of the blade. The shorter sight lines mean the visual distance between the blade and the material pile is shortened by about 40 percent, so less time is spent backing up to get a full view of the material and the job gets done faster.
In the cab, operators will find a more comfortable seat with improved suspension and multiple adjustments for personalized comfort. An easy-to-use 10-in. touchscreen main display, now common across much of the Cat dozer lineup, puts machine settings and features in easy view. A standard high definition rearview camera shows prominently in the main display.
The D4 includes several standard technology features aimed at helping operators work more efficiently, regardless of experience level. The cab also offers optimal interior mounting locations that make it simple to install the grade control system of choice.
An optional technology package includes the standard technology features, plus:
Customers also can add factory integrated Cat Grade with 3D. The system uses a GPS signal to automatically adjust blade movements — both lift and tilt — as the operator follows the design plan. Antennas and receivers are housed in a low-profile roof-mounted spoiler. An intuitive 10-in. grade operator interface works like a smart phone, making it easy for operators to pick up quickly. Android OS platform allows installation of custom apps for more versatility.
AutoCarry also is packaged with Grade with 3D, automating blade lift to help get more consistent blade loads with each pass and reduce track slip. Works seamlessly with Grade with 3D and Slope Assist.
With the capability of installing 3D grade systems from Trimble, Topcon and Leica, the D4 can easily integrate into job sites with existing grading technology infrastructures. All Cat Grade systems are compatible with Trimble, Topcon and Leica radios and base stations.
Longer service intervals contribute to up to 7 percent lower maintenance costs. Engine oil/engine oil filter service interval has been extended to 1,000 hours. [First change at 500 hours. Scheduled Oil Sampling (S·O·S) required. Please refer to Operation and Maintenance Manual (OMM) for details.]
Service intervals also have 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.
Cat Link telematics technology helps take the complexity out of managing job sites — by gathering data generated by equipment, materials and people — and serving it up in customizable formats.
The D4 is available in standard or low ground pressure (LGP) configurations. A variable pitch angle tilt (VPAT) blade is standard, with an option for a foldable VPAT blade to reduce transport width.
The D4 also can 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.
