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.
