C27 Engine with ACERT™ Technology
Optimizes engine performance and meets emission regulations.
C27Performing at full-rated net power of 433 kW (580 hp) at 1800 rpm with a torque rise of 21 percent, the D10T can doze through the toughest material. Matched to the high efficiency torque divider and electronically controlled power shift transmission, it will provide years of reliability.
ADEM™ A4 Engine ControllerThe ADEM A4 electronic control module manages fuel delivery and airflow to get the best performance per liter (gallon) of fuel used. It provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs.
MEUI Fuel SystemThrough the use of multiple injection fuel delivery, combustion chamber temperatures are lower, generating fewer emissions and optimized fuel efficiency. This is accomplished with the MEUI fuel system, which strikes the proper balance between the precision of the electronic control system and the simplicity of mechanically controlled unit fuel injectors. The result is more productivity and lower fuel consumption.
Air-to-Air AftercoolingAir-to-air aftercooling provides cooled compressed air to the engine intake manifold, thus reducing emissions and maximizing fuel efficiency.
Overhead CamsTwo, single overhead cams are driven by gears on the flywheel end of the engine. Placing them on the flywheel end significantly reduces noise and vibration. To reduce wear, two pendulum absorbers are mounted at the front of the camshafts. Together, these features contribute to the long-life and durability of this engine.

Implement and Steering Controls
Reduced operator fatigue for increased performance.
Dozer Control LeverA low-effort, electronic dozer control handle gives the operator control of all dozer functions with one hand. Fore/aft movement of the lever lowers and raises the blade. Left/right movement directionally tilts the blade. The thumb lever at the top of the handle controls blade pitch fore and aft. The trigger switch toggles between single and dual tilt. Blade response and blade float can be set/adjusted using the Advisor Panel. The left and right side thumb buttons provide control over the semi-automated blade pitch functions (load, carry, and spread) that the dual tilt attachment provides. The two buttons also provide control over the AccuGrade™ blade control attachment when the machine is so equipped. The buttons turn on AccuGrade, provide manual increment and decrement control, and turn off AccuGrade.
Electronic Ripper ControlA rigidly mounted handgrip provides firm support for the operator even when ripping in the roughest terrain. The low effort thumb lever controls raising and lowering. The finger lever controls shank-in and shank-out positioning. Programmable features, such as Auto Lift, Shank-out, and Auto Stow, increase efficiency for the operator.
Finger Tip Controls (FTC)Clustered for easy, one-hand operation to the operator's left. They control steering, machine direction and gear selection.
AutoCarry (optional)AutoCarry provides automatic blade control during the carry segment of dozing cycle. It is intended to enhance the operator's productivity in high production earthmoving with carry distances over 30.5 m (100 ft).
Computer Aided Earthmoving System (CAES) (optional)This on-board electronic site plan directs machine operators, in real-time, where to cut and fill. A graphical map of the design plan and a view of the machine’s horizontal and vertical position simplify operation and enhance production. This advanced information tool combines GPS technology (centimeter-level) and in-cab computing capabilities for precise grade and slope control. Ideal applications include benches, roads, leach pads, dump areas, and reclamation sites.
AccuGrade (optional)Automated blade control system that allows operators to grade with increased accuracy. Machine-mounted sensors are used to calculate precise blade slope and elevation.
Provides maximum efficiency in combination with the C27 engine.
Torque DividerA 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. The torque converter shields the driveline from sudden torque shocks and vibration.
