Hydraulics

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.

Power Train

The D10T2 power train design optimizes performance and ease of operation helping customers get more done for the lowest cost per unit.
Advanced Productivity Electronic Control System (APECS)
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).
C833154
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.
Bi-directional Shift
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.
Auto Downshift
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.
C833150

Steering clutches, brakes and final drives can be removed as a unit from each side of the tractor.

Undercarriage

The elevated sprocket and suspended undercarriage work together, increasing traction while creating a smoother ride for your operators. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts. These benefits translate into higher production and longer component life.
  • Bogie Suspension allows the track to conform to ground condition, providing up to 15% more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.
  • The integrated carrier roller mount is fabricated into the track roller frame making it easy to add optional carrier rollers in the field.
  • To further enhance durability where operating loads are highest, the redesigned roller frames consist of three (3) main castings to resist bending and twisting. The roller frame improvements also include larger rear major bogie pivot pins, redesigned carrier roller mounting pads, and improved major bogie mounting locations.
  • Track master link with single tooth and coarse thread bolts provide superior reliability and durability.
