Many tractors have mechanical brakes, operated by a linkage and cam system instead of a master/slave fluid system. These brakes are located on the rear axles, and work independently, so that they may be used to steer the tractor in tight corners or to reverse the direction of travel. The brake pedals will interlock for road travel, so that one pedal is not accidentally engaged by itself, causing the tractor to spin while traveling at a high speed.
The tractor also comprises manually operable left and right steering clutch control levers 31 and 32 and a single brake pedal 33. Transmission 4 is a power shift transmission for driving the tractor and has an output shaft 11 which extends into a housing 12 to drive a main shaft 13 through bevel gears 14.
