The Caterpillar 272D2 skid steer loader, 297D2 multi-terrain loader, and 299D2 compact track loader — along with their more powerful XHP counterparts — have a vertical-lift loader linkage and use a Cat C3.8 engine meeting U.S. EPA Tier 4 final emissions standards. Now standard on all six D2 Series models is the exclusive Caterpillar heads-up Advanced Display, and all feature a new engine-compartment sealing system for enhanced airflow debris control. Non-XHP models have increases in rated operating capacity (ROC), and XHP models now maintain their ROC numbers without external counterweights.

In addition to providing a theft deterrent system, the Advanced Display accommodates up to 50 operator security codes that allow each operator to adjust the machine to suit individual operating preferences. A full-color, 5-inch LCD monitor enables on-screen adjustment of implement response, hydrostatic drive response, creep control speed, ride control activation speed, language preference, and gauge layout selection. Electronic instrumentation includes fuel level, DEF (diesel exhaust fluid) level, hydraulic and engine coolant temperatures, and tachometer.

The 272D2, 297D2 and 299D2 models deliver ROC ratings of 3,400, 4,700, and 4,600 lbs., respectively, at 50% of tipping capacity. Ratings for the 272D2 XHP, 297D2 XHP, and 299D2 XHP are 3,650, 4800, and 4,725 lbs., respectively, at the 50% rating. For applications that require additional lifting capacity, all six models can be equipped with optional bolt-on external counterweights.

The C3.8 engine, rated at 98 gross hp in non-XHP models and 110 in XHP models, now uses a selective catalytic reduction (SCR) system for control of nitrogen-oxide emissions to meet Tier 4 final emissions standards.

The SCR system requires no maintenance other than periodic addition of DEF. The DEF level is easily monitored via the digital gauge provided on the standard Advanced Display. All D2 models have a lockable door cover for the DEF fill point, located on the right side of the machine. The DEF fill is identified with the industry-standard blue cap and has a smaller filler neck to deter filling with an incorrect fluid.
