The Cat ® D11 Dozer delivers higher productivity at lower cost — for a reduction of up to 6% in overall cost per bank cubic meter compared to the previous model. Infused with performance-enhancing features, the D11 helps you improve the efficiency of your dozing operation. The torque divider with stator clutch automatically frees up the stator when torque is not required, delivering higher drivetrain efficiency for reduced fuel consumption. High-horsepower reverse speeds up non-productive traveling to reduce cycle time, while load-sensing hydraulics deliver more power to the dozer, increasing responsiveness and boosting fuel efficiency. Advanced technologies are completely integrated into the dozer, creating smart machines and more informed operators to maximize the productivity of your operation.
