Transmission

Transmission — Power Director

Transmission	Power Director
Type	two-speed power shift
Gears	8 forward and 2 reverse
Clutch	dry disc
Oil capacity	24 qts 22.7 L
The transmission is controlled by means of the gear shift lever and the Power Director lever. The tractor must be stopped, and clutch used, to select one of four forward gears, or reverse. The Power Director lever has high, low, and neutral positions. The Power Director can be shifted on the move without clutching. Placing the Power Director into neutral causes the tractor to stop while keeping the PTO engaged.
