Final Drive. The planetary final drive causes speed reduction and an increase in torque at the tractor wheels. Power
from the differential turns the axle shafts; the shafts turn the sun gear in the center of the planetary gears. The movement
of the planetary gears causes the planetary carrier to turn; in turn the wheels are turned.
