A bi-directional tractor exhaust system includes a downwardly directed exhaust pipe connected to an upwardly directed exhaust pipe. An exhaust pipe valve may be mounted in the downwardly directed exhaust pipe. An actuator may be connected to the exhaust pipe valve and may be moveable between a first position opening the exhaust pipe valve to direct exhaust through the downwardly directed exhaust pipe, and a second position closing the exhaust pipe valve to direct exhaust through the upwardly directed exhaust pipe.
