Abstract: Methods and apparatus for a lawn maintenance vehicle park brake and traction drive interlock are provided. A park brake mechanism is selectively operable between an engaged position and a disengaged position. A traction drive is also mounted to the lawn maintenance vehicle, the traction drive having a disable mode which prohibits transmission of a driving force from the traction drive to a drive wheel. A first operable connection between the park brake mechanism and a wheel brake activates the wheel brake. A second operable connection between the park brake mechanism and the traction drive activates the disable mode of the traction drive. A method of controlling a lawn maintenance vehicle with a park brake and traction drive interlock include the steps of providing a lawn maintenance vehicle, providing an operable park brake mechanism, providing a first operable connection, and providing a second operable connection.
