C27 Engine with ACERT™ Technology

Optimizes engine performance and meets emission regulations.


Performing 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 Controller

The 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 System

Through 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 Aftercooling

Air-to-air aftercooling provides cooled compressed air to the engine intake manifold, thus reducing emissions and maximizing fuel efficiency.

Overhead Cams

Two, 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.


Easier maintenance and repair through monitoring key functions and logging critical indicators. Electronic diagnostic access is possible with the Cat Electronic Technician.

Operator Station

Operator Controls

Power train and implement controls are conveniently placed for low operator fatigue and ease of control.

Cat Monitoring Display System

The combination dash mounted instrument cluster and the Advisor Monitoring System provide key machine operating information and give the operator and service technician insight into the machine's operation and maintenance needs.

Wide Panoramic View

A large view hole in the single-shank ripper frame provides a view of the ripper tip. The tapered hood, notched fuel tank, and narrow ripper carriage gives the operator a clear line of sight to the front and rear work areas. The single-pane door windows provide an excellent view to the sides and blade.

Fuse Panel and Diagnostic Access

The new compartment features a single location fuse panel that includes a diagnostic port for the Cat ET to connect for rapid machine diagnostics.

Comfortable Operation

Standard isolation-mounted cab reduces noise and vibration. The Cat Comfort Series Seat is fully adjustable and designed for comfort and support. Conveniently located air circulation vents evenly distribute airflow within the cab. Optional air conditioning available.

Implement and Steering Controls

Reduced operator fatigue for increased performance.

Dozer Control Lever

A 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 Control

A 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.

Drive Train

Provides maximum efficiency in combination with the C27 engine.

Torque Divider

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. The torque converter shields the driveline from sudden torque shocks and vibration.

Planetary Power Shift Transmission

Three speeds forward and three speeds reverse, utilizing large diameter, high-capacity, oil-cooled clutches.
  • Modulation system permits fast speed and direction changes.
  • Modular transmission and bevel gear slide into rear case for servicing ease, even with ripper installed.
  • Oil-to-water cooler for maximum cooling capacity.
  • Forced oil flow lubricates and cools clutch packs to provide maximum clutch life.

Electronic Clutch Pressure Control

Provides smoother shifting by modulating individual 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.

Drawbar Pull vs. Ground Speed

As loads on the tractor increase, the D10T offers unmatched lugging capability and smooth shifting as the need occurs to change gears under varying loads. The 3-speed forward, 3-speed reverse transmission offers excellent runout speeds.

Elevated Final Drives

Isolated from ground and equipment induced impact loads for extended power train life. Crown-shaved drive gears provide smooth, quiet, low maintenance operation. Splash lubrication and Duo-Cone™ Seals extend service life.

Modular Power Train

The modular power train design permits quick removal and installation of major components such as the engine, transmission and final drives.


Designed for optimized machine balance and the best performance.

Suspended Undercarriage Design

Absorbs impact loads, to reduce the shock loads transferred to the undercarriage, by up to 50%.

Bogie Suspension

Bogie suspension conforms closely to the ground providing up to 15 percent more ground contact, especially in uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.

Integrated Carrier Roller Mount

The carrier roller mount is cast into the track roller frame making it easier to add the optional carrier roller in the field, if conditions require it.

Rollers and Idlers

Feature symmetric Duo-Cone seals for long sealing life to prevent oil loss and dirt entry. Toric rings maintain performance over a wide range of temperatures.

Roller Frames

Roller frames are tubular to resist bending and twisting, with added reinforcement.

Positive Pin Retention (PPR) Sealed and Lubricated Track

Designed for high-impact and high load applications, the Caterpillar design locks the link to the pin.

Sprocket Segments

Made exclusively of Cat Tough Steel™ for longer wear life and precision machined for fit.

Track Shoes
