Power is transferred from the engine flywheel to the torque divider. The torque divider, consisting of a torque
converter and a planetary gear set, transfers power through a driveshaft to the transmission. The transmission has
three forward and three reverse speeds. Speed and direction clutches are electronically controlled to transfer
power to the bevel and transfer gears, which in turn send power to the steering differential and brake assembly (on
right side of machine) and the planetary gear and brake assembly (on left side of machine). These two assemblies
transfer power through two outer axle shafts to the final drives, which utilize two planetary gear sets to increase
torque. Sprockets on the final drives transfer power to the track assemblies which propel the machine. Steering is
accomplished by increasing power (speed) to one track while equally reducing power (speed) to the other track.
