Which floor pedal engaged reverse gear on most Ford Model Ts?

On most Ford Model Ts, the center floor pedal engaged reverse gear. This unusual arrangement was part of the car’s planetary transmission, whose controls differed sharply from those in later automobiles.

The Model T had three floor pedals, but they did not correspond to modern clutch, brake, and accelerator pedals. The left pedal controlled the forward transmission bands: pressing it selected low gear under the appropriate lever setting, while releasing it allowed high gear. The center pedal selected reverse when the transmission was in neutral. The right pedal operated the transmission brake.

The car’s throttle was controlled by a hand lever on the steering column rather than by a conventional accelerator pedal. A separate lever beside the driver controlled the parking brake and helped determine the transmission’s operating mode. Learning to drive a Model T therefore required remembering a completely different control sequence.

The wording “most” matters. The first 800 Model Ts used a lever to select reverse; after those early cars, reverse was operated through the center pedal. That historical exception does not make the stored answer wrong for the question as phrased.
