Transmission & PTO


Transmission options
Summary	8-speed / 16-speed


Transmission
Transmission	sliding gear
Gears	8 forward and 4 reverse
Clutch	12-inch dry disc
Oil capacity	68 qts 64.4 L
Oil type	IH Hy-Tran
Summary	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.


Transmission
Transmission	Torque Amplifier
Gears	16 forward and 8 reverse
Clutch	12-inch dry disc
Oil capacity	68 qts 64.4 L
Oil type	IH Hy-Tran
Summary	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.
