Caterpillar introduces the new D4 tractor


0

When Cat first announced the switch from the D6K2 to the D4, the name change wasn’t referring to a new machine. “We just pulled out the old label and put it on the new label,” Sam Meeker, Cat Product Applications Specialist, told Equipment World last year. This is no longer true. Now it’s time for the D4 to shine in the new Cat tractor line, and the improvements over the previous D6K2/D4 are notable. These include an increase of up to 30% in visibility for the area in front of the blade. Cat says these shorter lines of sight mean that the visible distance between the blade and the pile of material is shortened by about 40% so operators spend less time backing up. The visible distance between blade and pile of material on the Cat D4 has been shortened by about 40%. The D4 now shares 130 net horsepower in the 10-inch main touch screen, and is common on most of the Cat tractor lineup. Cab features include a standard HD rear view camera.[Related: Check out our video on why Cat renamed the Cat D6K2 the D4.]If you choose Cat Grade with 3D, the 10″ grade launcher interface is designed to work like a smartphone. And you can install custom apps for Android. Standard technology features include: Slope Indicate displays the device’s main operating system and cross-slopes on the home screen. The stable blade works with operator blade inputs for smoother surfaces Slip Control automatically reduces track slip to save time, fuel and track wear Optional technology on the D4 includes: Cat Grade with Slope Assist that provides essential blade positioning without additional hardware or GPS signal. The Factory Accessory Mounting Option (ARO) offers mounting locations, brackets, and hardware, designed to simplify installation of any brand of grade control system and allow easy uptake of your preferred grading technology. All Cat Grade systems are compatible with Trimble, Topcon and Leica Geosystems radios and base stations. The Cat Grade with 3D uses a GPS signal to automatically adjust lift and tilt blade movements when the operator follows the design plan. The low ceiling wing contains the system’s antennas and receivers. The system also includes Cat AutoCarry, which automates blade lift and is designed to deliver more consistent blade loads in every pass and reduce track slip. The Cat D4’s longer service intervals reduces maintenance costs by up to 7% over its predecessor. Intervals —1,000-hour engine oil and filter changes using the Cat Scheduled Oil Sampling Program — contribute to a 7% reduction in maintenance costs. Service intervals for the air cleaner and diesel exhaust fluid pump filter have also been extended. LED lights provide up to six times the life of halogen. You can choose either the low ground pressure or the standard configuration of the track. The standard variable tilt angle blade comes with a foldable option to reduce transport width. Forestry and land clearing contractors can opt for specialized guarding that protects against airborne impacts and debris. An impact-resistant cab with polycarbonate windows is also available.
