The D3K2 track-type tractor from Caterpillar Building Construction Products includes an engine meeting U.S. EPA Tier 4 Final/EU Stage 4 emissions standards. It has automatic traction control, slope indicate and available slope assist with hydrostatic drive, stable blade and power pitch systems, eco mode, and spacious operator’s stations with climate comfort. With a power rating of 80 hp, it uses a CAT C4.4 ACERT engine that meets stringent emissions standards with the NOx Reduction System (cooled exhaust gas recirculation), maintenance-free diesel oxidation catalyst and selective catalytic reduction system. It has precision blade control for grading applications and automatic traction control that reduces track slippage when the machine encounters maximum load conditions. Slope indicate accurately displays the machine’s blade cross-slope direction, as well as its main-fall (fore/aft) direction, eliminating guesswork and allowing operators to grade with assurance. Slope assist facilitates achieving the required main-fall by automatically maintaining pre-established blade angles. 919/465-6877; www.cat.com
