The new Cat D11T and D11T CD (CarryDozer) incorporate recent design refinements that include an Enhanced Auto Shift system, Dynamic Inclination Monitor, automatic climate control and available automated ripper control. Blade capacities for the new models range to 57 cubic yards and operating weights to 248,456 pounds.   

The Cat C32 engine used in these new models is rated at 850 net horsepower and is available in two configurations, meeting U.S. EPA Tier 4 Final emissions standards in those geographical regions requiring a high degree of emissions control, and in lesser-regulated areas, the engine will be configured to meet U.S. EPA Tier 2-equivalent emissions standards.

The Enhanced Auto Shift (EAS) system is designed to conserve fuel by automatically selecting the optimal reverse gear and engine speed, based on load and desired ground speed. When the EAS mode is not activated, an Auto Downshift feature automatically changes gears to most efficiently handle loads.

A new Dynamic Inclination Monitor provides a readout of tractor pitch angle and side-to-side slope angle, and Automated Blade Assist Control uses preset blade-pitch positions to simplify positioning. An optional Autocarry system automatically controls the blade during the carry segment.

The new operator-presence system locks out the power train and hydraulic system to avoid unintentional machine movement when the operator is entering or leaving the cab, which can be done via an optional hydraulically actuated access ladder that deploys and stores in seconds.

An optional sound-suppression package reduces average sound power levels for both the operator and the bystander.
