Transmission notes

8-speed gear: Four gears each provided in high, low, and reverse ranges.

Torque Amplifier: The Torque Amplifier (TA) provides a shift-on-the-move underdrive to the standard transmission. In any gear and range, the transmission can be shifted from direct drive (DD) to the slower TA speed by simply pulling the TA lever back. No clutching or stopping is needed.

hydrostatic: The hydrostatic transmission option ended in 1973 when the Hydro 100 began production.
