The invention discloses a front-and-back pneumatic traveling brake system for an agricultural tractor. An air compressor is used for generating compressed gas, and a pressure regulating valve is mounted at the outlet of the air compressor and used for regulating the pressure of the compressed gas; a one-way valve is mounted at the outlet of the pressure regulating valve and used for preventing the compressed gas from flowing backwards; the compressed gas enters a wet gas storage cylinder through the one-way valve so as to perform oil-water separation, and then the compressed gas after oil-water separation enters two chambers of a two-in-one main gas storage cylinder through two circuits divided by a four-circuit protection valve; a brake master pump is connected with the two chambers of the two-in-one main gas storage cylinder through two gas inlets respectively, and the brake master pump is connected with front brake chambers and rear brake chambers through two gas outlets respectively. When a traveling brake pedal is trodden, a push rod of the brake master pump is driven to move forwards, and the compressed gas is pressed into the front brake chambers and the rear brake chambers respectively, so that traveling brake is realized. The front-and-back pneumatic traveling brake system disclosed by the invention can guarantee the traveling brake to be safe, stable and reliable when the tractor travels, and can avoid direction deflection and insufficient braking force during braking.
