The Cat D1, D2, and D3 Next Generation small dozers feature styling changes, technology enhancements, and a new low-emission fuel-efficient engine. The D1, D2 and D3 Next Gen dozers replace the D3K2, D4K2, and D5K2 models, respectively, and the new series offers the same specialty model options as in the past.

A new lower sloping hood line improves visibility over the top of the hood to the peripheral view and blade’s cutting edge to increase finish grade efficiency.

A larger 10-inch primary display with color touch screen provides easy access to many of the standard and optional advanced technology features. Reducing track slip when the machine encounters maximum load for greater productivity of each cycle, standard Automatic Traction Control no longer requires operator interaction as with previous models. Slope Indicate improves operator confidence when working on slopes by providing slope of the chassis in the cross-slope direction without guessing. Stable Blade complements operator blade control input, allowing the operator to finish grade easier, quicker, and with less effort.

Available as part of the Cat attachment ready option (ARO), Slope Assist saves time by helping the operator to more easily achieve the desired blade mainfall slope (fore/aft) and cross slope (left/right) by automatically maintaining the operator’s established blade grade angles.

The new dozers are powered by the Cat C3.6 diesel engine, which now meets U.S. EPA Tier 4 Final emission standards. For markets with less strict emissions standards, a Tier 3 equivalent engine is available with the same net power ratings as the Tier 4 Final engines. The dozers’ large, hinged door providing easy engine service access to all regular engine maintenance points has been moved to the right-hand side of the new machines.

These new Next Gen dozers deliver up to 10% improved fuel economy. Eco Mode, available in forward/reverse or reverse only options, improves fuel economy by automatically reducing engine speed when not required. When load changes necessitate higher engine RPM, Eco Mode automatically allows the engine to deliver maximum speed and power until the load decreases.
