New Cat® D1, D2 and D3 Next Generation Small Dozers Improve Visibility, Grade Control and Fuel Economy

For Release in Brazil: November 2022
Release Number: 682PR22

The Cat^® D1, D2 and D3 Next Generation Small Dozers feature styling, technology enhancements and a new low-emission fuel-efficient engine that provides significant value for the customer. The series also includes the D1 Mulcher specialty model.

These next gen small dozers are designed to optimize speed, transportability, maneuverability, versatility and finish grade accuracy. A low sloping hood line provides visibility over the top of the hood to the peripheral view and blade’s cutting edge to increase finish grade efficiency.

A large 10-in (254-mm) primary display with color touch screen provides easy access to many of the standard and optional advanced technology features. 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) for easy scalability to GRADE with 3D control systems, 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 dozers’ Power Pitch option enables the operator to control blade pitch (fore/aft) remotely from the operator’s compartment to optimize blade pitch for blade loading, optimizing machine productivity by up to 6 percent.

Two undercarriage configurations – standard and LGP (low ground contact pressure) – are offered for the next gen small dozers. The LGP 30-in (762-mm) track will be offered for the D1 and D3 models to improve traction and flotation in exceedingly marginal underground conditions. The choice between sealed and lubricated track (SALT) and Cat Abrasion™ undercarriage systems provides customers with the lowest operating cost solution for their specific applications.

New Power Unit

The D1, D2 and D3 Next Gen Small Dozers are powered by the fuel-efficient Cat C3.6 diesel engine. The dozers’ large, hinged door provides easy engine service access to all regular engine maintenance points.

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.

A host of optional features helps the customer to optimize engine operation, based on operating conditions. The available turbine type precleaner increases engine air filter life when working in excessive debris conditions. An automatic reversing fan reduces debris build-up in the radiator and engine enclosure by reversing fan direction at a predetermined interval without the need for operator input. Access to the radiator without tools for periodic cleaning is facilitated by the hinged radiator grille option.

Caterpillar will also introduce the D1 Mulcher specialty configuration into the Brazil marketplace. The Cat D1 Mulcher is specially designed to optimize performance when clearing a mix of small- to medium-diameter materials. Design-matched with the rugged Cat HM518 Mulcher, the D1 Mulcher clears a 188.2 cm (72 in) wide strip on each pass, making it the right machine for right-of-way construction and maintenance, site development, tree management and firebreak clearing.
