Three easy-to-transport models designed to optimise speed, manoeuvrability and versatility with accuracy of finished grade
Caterpillar has introduced three new small bulldozer models that build on the same base machine platform as their successful predecessors. The new Cat D1, D2 and D3 Next Generation 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.
Cat says these Next Gen small dozers are designed to optimise speed, transportability, manoeuvrability, versatility and finish grade accuracy. 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 254mm primary display with colour 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.
Two undercarriage configurations – standard and LGP (low ground contact pressure) – will continue to be offered for the Next Gen small dozers. The XL designation will no longer be used with the new series. The LGP 762mm track will be offered for the D1 and D3 models to improve traction and flotation. The choice between sealed and lubricated track (SALT) and Cat Abrasion undercarriage systems provides the lowest operating cost solution for specific applications.
The new small dozers are powered by the fuel-efficient Cat C3.6 diesel engine developing 80, 92 and 104hp in the D1, D2 and D3 respectively, and meeting Tier 3 emission standards. 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.
