The Caterpillar D3K2, D4K2, and D5K2 track type tractors meet U.S. EPA final Tier 4 emissions standards. With respective power ratings of 80, 92, and 104 hp, the models all use the Cat C4.4 ACERT engine, which meets emissions standards with only the Cat NOx reduction system (cooled exhaust gas recirculation), diesel oxidation catalyst, and selective catalytic reduction system.

Automatic Traction Control, new for the K2 models, reduces track slippage when the machine encounters maximum load conditions. This feature automatically adjusts machine operating parameters to keep the machine moving steadily and productively through the cut, minimizing the operator's need to continually adjust the blade to prevent stalling. The net results are more consistent grades, reduced operator fatigue, and substantially improved undercarriage life.

Also new for the K2 machines are the standard Slope Indicate and available Slope Assist features. Slope Indicate accurately displays the machine's blade cross-slope direction, as well as its main-fall (fore/aft) direction, eliminating guesswork.

Slope Assist facilitates achieving the required main-fall by automatically maintaining pre-established blade angles. Consistent grades are attained more quickly with the system, fill materials are conserved, and less-experienced operators are more productive. The system is part of the Cat AccuGrade Ready attachment, allowing the system to be easily upgraded to 3D capability.
