Engineered for maximum production and service life.Learn More
We help reduce downtime by making our machines easy to repair and maintain. The D11T/D11T CD mainframes are built to absorb high impact shock loads and twisting forces during severe dozing and ripping applications. It is not uncommon to see these machines rebuilt several times using the same frame, with only minor welding.
The Carrydozer frame is specifically designed to accept the additional frame loads generated by the unique Carrydozer blade design.
The tag link is designed to increase blade penetration and pry-out force as well as increase machine maneuverability and balance. The closer the blade is kept to the machine, the easier it is for the operator to maneuver near obstacles. Keeping the blade closer to the machine also reduces the lever effect on machine balance, especially when working around high-walls, affording the operator increased confidence.

C32 with ACERT Technology
Designed to deliver the performance and maximum fuel efficiency you demand, the D11T/D11T CD features a Cat C32 ACERT engine. A U.S. EPA Tier 4 Final engine is available for sale in the United States and Canada.
ADEM™ A4 Engine Controller
The ADEM A4 electronic control module manages fuel delivery and air flow to get the best performance per liter (gallon) of fuel used.
• Provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs.
Air-to-air aftercooling on the D11T/D11T CD cools hot, compressed air coming out of the turbocharger providing cooler and denser air into the air intake system. Bringing more cool air into the engine increases power generation, lowers emissions, and improves fuel efficiency.
Engine enclosures provide easy access to maintenance points within the engine compartment. Easier maintenance and repair is available through monitoring of key functions and logging of critical indicators.
Providing you reliable, integrated solutions.Learn More
You can continue to count on the C32 ACERT engine meeting U.S. EPA Tier 4 Final emission standards to work productively and economically in tough applications. It delivers the power and torque you need for optimal performance.
The U.S. EPA Tier 4 Final emission standards are met on the D11T/D11T CD in the United States and Canada using:
Superior cooling in the most demanding work conditions.Learn More
The hydraulic variable demand fan provides engine cooling capability that is matched to the ambient conditions. In cooler conditions, the fan turns at a slower speed, reducing power demands. This reduces fuel consumption in lower load factor operations. Low speed fan operation also reduces both the operator and spectator sound levels.
Aluminum Bar Plate Radiator
The cooling system uses a two-part radiator built with rugged, highly efficient aluminum bar plate cores. The aluminum bar plate construction aids durability and allows for higher heat transfer and superior corrosion resistance.
Hydraulic Air to Oil Cooler
The new air to hydraulic oil cooler reduces hydraulic oil temperatures thus improving component life. The core is built using the same rugged aluminum bar plate design as the jacket water cooler.
Power and control to efficiently move your material.Learn More
The Cat D11T/D11T CD use a torque divider between the engine and the transmission to act as the hydrodynamic component, reducing the possibility of damage to the powertrain by dampening impact loads and vibrations.
• A single-stage torque converter with output torque divider sends 75 percent of engine torque through the converter and 25 percent through a direct drive shaft for greater driveline efficiency and higher torque multiplication.
Planetary Powershift Transmission
The Cat Planetary Powershift Transmission offers three speeds forward and three speeds reverse, utilizing large diameter, high-capacity, oil-cooled clutches.
Steering Clutch and Brake
Fade resistant and adjustment free. The multi-disc, oil cooled steering clutches are hydraulically applied and electronically controlled. The brakes are applied by springs and hydraulically released for safe and reliable braking performance.
Designed for optimized machine balance and best performance.Learn More
The elevated sprocket and suspended undercarriage work together, increasing traction and giving the operator a smoother ride. These benefits translate into higher production and longer component life. This design transfers implement shock loads to the mainframe, so final drives, axles, and steering components are isolated from harsh impact loads commonly seen in large track-type tractor applications.
Designed for your comfort, convenience, and productivity.Learn More
The D11T/D11T CD cab is designed and equipped for operator productivity, safety, and comfort. Electro-hydraulic controls require low effort to control steering and implements. This helps to reduce operator fatigue and to improve productivity. The monitoring system display, with easy-to-read gauges, indicators and warning lamps, keeps the operator aware of machine conditions. All of these features provide the D11T and D11T CD an industry leading operator environment that provides high productivity, efficiency, and comfort.
The Finger Tip Controls (FTC) require less effort and are more comfortable for long periods of operation. Single-hand controls located on the left armrest coordinate steering using left and right finger paddles located ahead of the handgrip. The D11T/D11T CD uses electro-hydraulic clutch-brake steering.
Low effort and comfortable to grip, the electronic dozer joystick gives the operator control of all dozer functions with the right hand.
A rigidly mounted handgrip on the electronic ripper control provides firm support for the operator even when ripping in the roughest terrain. Low effort thumb lever controls raising and lowering.
Greater productivity through integrated electronic systems.Learn More
The D11T electronic systems have been completely integrated to function as one machine. This integration creates a smart machine and more informed operator maximizing the productivity of both.
