Better sight lines save time on the Cat D4 dozer

By Jenny LescohierJuly 12, 2021

Shorter sight lines mean the visual distance between the blade and the material pile is shortened by about 40%, so less time is spent backing up to get a full view of the material

The Cat D4 dozer, formerly the D6K2, is considered a fan favorite for its power, precision and optimized balance, the manufacturer claims, and now it’s been designed to offer more value with improved sight lines, reduced operating costs and a broad choice of easy-to-use technology features. 

The D4 weighs in at 29,259 lbs., with a net power of 130 hp. D4 LGP has an operating weight of 30,882 lbs.

Caterpillar said a lower sloping hood line provides up to 30% 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%, 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 the seat designed for comfort with improved suspension and multiple adjustments for a personalized fit. A 10-inch touchscreen main display, now common across much of the Cat dozer lineup, puts machine settings and features front and center, while a standard High Definition rearview camera shows prominently in the main display.

The D4 also 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.

  • Slope Indicate shows machine mainfall and cross-slope on the main display for easy reference.
  • Stable Blade works seamlessly with operator blade inputs for smoother surfaces.
  • Traction Control automatically reduces track slip to save time, fuel and track wear

An optional technology package includes the standard technology features, plus:

  • Cat Grade with Slope Assist provides basic blade positioning assistance without added hardware or a GPS signal. 
  • Factory Attachment Ready Option (ARO) provides optimal mounting locations, brackets and hardware, and simplifies installation of any brand of grade control system.

Customers can also 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.

A 10-inch operator interface is designed to work like a smart phone so it’s easier for operators to pick up quickly. Android OS platform allows installation of custom apps for more versatility.

AutoCarry is also 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 jobsites 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% lower maintenance costs, Caterpillar said. Engine oil/engine oil filter service interval has been extended to 1,000 hours. 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 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 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.
