Helping you get more done with maximum availability, the D10T2’s durable design makes repair and maintenance easy. Customers can rebuild these tractors several times using the same frame with only minor repairs.

The D10T2 mainframes are built to absorb high impact shock loads and twisting forces encountered during severe dozing and ripping applications.
The main case, equalizer bar saddle, and front cross member are heavy duty steel castings incorporated into highly loaded areas of the mainframe to improve stress distribution for improved durability.
Top and bottom rails are made from continuous rolled sections, providing superior mainframe durability.
The main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.
The pivot shaft and pinned equalizer bar maintain track roller frame alignment and allow the roller frame to oscillate for smoother ride.

Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost.

The remote lubrication for the D10T2 is performed from a service point conveniently located on the left hand fender and allows an operator or service technician to lubricate both the left-hand and right-hand equalizer bar end pin bearings and pins from one service point.
Adding the optional autolube system allows the operator to tailor the amount of grease needed for each application by volume and service interval through the Information Display.

The evolution of the D10T to the D10T2 is all about maximizing productivity while increasing fuel efficiency. The Cat C27 engine with ACERT Technology delivers power and reliability, ensuring top performance, high productivity, and exceptional service life.

The C27 ACERT engine performs at full rated net power (SAE J1349/ISO 9249) of 447 kW (600 hp) at 1,800 rpm with a high torque rise of 21 percent (in forward gears), allowing the D10T2 to doze through tough material.
Matched with a high efficiency torque divider and electronically controlled power shift transmission, it will provide years of dependable service.

Helping you maximize the material moved for every drop of fuel, the C27 ACERT engine utilizes the A4E4 Engine Controller, which automatically switches engine power settings based on direction of travel.

The D10T2 can deliver rated net power (SAE J1349/ISO 9249) of 538 kW (722 hp) in reverse.
With approximately 20% more power in reverse you can return faster for reduced cycle times increasing productivity and lowering the cost per unit of material moved.

Bringing more cool air into the engine increases power generation, lowers emissions, and improves fuel efficiency. • Air-to-Air Aftercooling on the D10T2 cools hot, compressed air coming out of the turbocharger providing cooler and denser air into the air intake system.

The D10T2 provides durable, efficient cooling for the most demanding conditions encountered on job sites.

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.

Helping to save on repair and maintenance costs, the oil to air hydraulic cooler helps extend component life by reducing hydraulic oil temperatures.

Customers experience increases in production and fuel economy as well as reductions in fan noise and engine overcooling with the hydraulically variable demand fan. The demand fan operates to match the ambient conditions. In cooler environments, the fan turns at a slower speed; it consumes only the power required to cool the tractor systems, providing more power to the tracks to help you lower your cost per unit of material moved.

Fuel efficiency and performance are improved with field-proven load-sensing implement hydraulics on the D10T2, which respond to operating requirements by automatically and continually adjusting implement hydraulic power. Tractor performance is improved because hydraulic flow is provided only when implement commands are made. Therefore, more horsepower is available at tracks to move the machine ahead.

The D10T2 Load-sense hydraulics have improved multi-function interaction providing enhanced control of blade during dozing allowing for efficient movement of material.
Twin implement pumps matched with newly designed valves offer simultaneous dozer commands such as tilt, pitch, and lift, as well as simultaneous ripper commands like lift and pitch. This functionality increases performance and improves operator efficiency.
The D10T2 provides unmatched single and dual tilt pry-out forces. The machine now has individual tilt valve sections that provide equal tilt pry-out force on left and right sides with dual tilt.

The D10T2 power train design optimizes performance and ease of operation helping customers get more done for the lowest cost per unit.

Is a key contributor to improved speed shift performance and quality in the D10T2. The operator will notice enhanced comfort during speed shifting resulting in an increased level of operator productivity. Most importantly, the improved shift quality provided by APECS is a key enabler to obtaining the full benefits of Enhanced Autoshift (EAS).

A standard feature for the D10T2 is EAS. EAS improves fuel efficiency and productivity by automatically selecting the optimal gear and engine speed combination based upon power train load and desired ground speed. This feature functions similar to an automatic transmission. EAS functionality combined with the increased power in reverse will enhance productivity when backing up on slopes.

This convenience feature helps reduce operator work load during operation. Bi-directional shift allows the operator, by just making a directional change, to automatically select the desired forward and reverse gears or the desired forward and reverse speeds when EAS is activated.

This feature adds value by enhancing safety and productivity during the dozing cycle. When not in EAS mode, Auto downshift can be used to automatically downshift the transmission when significant load increases are detected, but this feature will not automatically up-shift when load is reduced. Auto downshift provides optimal performance with minimal operator effort. Operator may override these automatic shift features at any time.

A single stage torque converter with output torque divider sends 75% of engine torque through the converter and 25% through a direct drive shaft for greater driveline efficiency, higher torque multiplication, and ease of operation.
