Powertrain
Powerful efficiency
From engine to transmission to final drives, the D8T powertrain is designed to turn power into productive work. The D8T
offers unmatched lugging capability and smooth shifting when changing gears under varying loads. The 3-speed forward,
3-speed reverse transmission, backed by differential steering, offers excellent run out speeds and accurate steering capability.
Torque Divider
A robust, high efficiency torque divider provides high torque multiplication to move heavy loads, while shielding the drive train
from sudden torque shocks and vibration.
Differential Steering System
Differential steering maintains full power to both tracks for best-in-class turning under load. When one track speeds up, the
other slows down an equal amount. Maneuverability – especially with large blade loads – is improved, as well as cycle times
in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes
because both tracks are powered during turns.
Planetary Power Shift Transmission
The planetary power shift transmission offers smooth shifting and quick speed and directional changes for maximum productivity.
The transmission is built for long life, and a modular design allows for ease of service without removing other components.
Enhanced Auto Shift
The new Enhanced Auto Shift feature uses the simple “shift up, idle back” principle during forward and reverse travel to save
fuel and improve overall dozing cycle fuel efficiency.
Auto-Shift/Auto-Kickdown
Auto-shift allows the operator, by just making a directional change, to go from preset forward to preset reverse gears.
Auto-kickdown automatically downshifts the transmission when significant load increases are detected. These features are
especially useful when backfilling or rough grading. Operators can select from a variety of settings, and can override the
automatic shift features at any time.
