The tractor must be stopped to shift the transmission (except the TA). The right-most console lever selects range (high, low, or reverse) and the left lever selects one of four gears. The Torque Amplifier (TA) is on the left side of the instrument panel and may be shifted without the clutch. Pulling back engages the TA, reducing the ground speed. Pushing the lever forward puts the transmission in direct drive (DD) mode.Reference
