Caterpillar’s Tier 4 Final D3K2, D4K2 and D5K2 track-type tractors are now available with Cat Grade Control 3D, which automates machine functions during both production dozing and fine grading applications. The system's integrated design includes dual, roof-mounted antennas and an inertial measurement unit that senses machine orientation, GNSS (Global Navigation Satellite System) receivers, data radio, position-sensing hydraulic cylinders, joystick buttons for rapid grade adjustments. A full-color grade-control display visually indicates grading progress. Three “intelligent" operating features allow the machine to match blade loads with ground conditions, resulting in consistently full blades with reduced operator effort. The AccuGrade Ready Option is part of the package, adding versatility by allowing other Cat GRADE technologies to be used, such as AccuGrade Laser or a universal total station when satellite reception is limited.

The D3K2, D4K2 and D5K2 also include automated slope measuring and traction control. Standard Slope-Indicate’s position sensors measure cross slope and main fall (fore/aft slope) to show the operator the grade under foot. A less than $7,000 option adds Slope-Assist, which keeps the blade at the selected slope no matter how the operator adjusts the blade. Automatic Traction Control reduces track slippage without operator intervention when the machine encounters maximum load. The system adjusts machine operating parameters to keep the blade moving steadily and productively through the cut, minimizing the operator's need to adjust the blade to prevent stalling.

  • Slope-Assist is part of Cat AccuGrade Ready attachment, and can be easily upgraded to 3D control
  • Cat C4.4 ACERT diesel engines rated at 80, 92, and 104 hp
  • Tier 4 Final compliant with the Cat NOx Reduction System (cooled exhaust gas recirculation), maintenance-free diesel oxidation catalyst, and selective catalytic reduction
  • Premium features retained from predecessor models: hydrostatic drive, Stable Blade, Power Pitch, Eco Mode, and operator's stations with improved climate controls
  • Eco Mode maintains optimum engine speed for the load on the blade, delivering max. power as required and improving fuel economy up to 20%
  • Stable Blade complements operator blade-control input, delivering finer control and more consistent grades
