Transmission

Type	sliding gear, Torque Amplifier

Notes	The 706 transmission is controlled by means of two levers. A range lever selects high, low, reverse range, or neutral. A separate speed lever selects one of four speeds. The tractor must be stopped, and the clutch used, to change range or speed gears. The Torque Amplifier (TA) provides a hydraulically-actuted under-drive that may be shifted, on the move, with any range and speed selection in the main transmission. Using the TA does not require the clutch or stopping the tractor. With the lever in the forward position, the TA is disengaged and the transmission is in direct drive. To slow the tractor (increasing pulling power) the TA lever should be pulled smoothly and quickly to the rear, engaging the TA. To disengage the TA and return to direct-drive, the TA should be moved forward, with a slight pause at the center position of the lever.
