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.

With 12.4-26 rear tires.

The shuttle transmission is controlled using the gear shift lever and the shuttle control lever. The tractor must be stopped, and clutch used, to select one of four speeds with the gear shift. The shuttle control lever enables a shift between forward, reverse, or neutral without clutching. A PTO could be ordered on the industrial D15 with the shuttle, but it ran at 875 RPMs.
