Abstract
A riding lawnmower includes a parking brake handle movable between an engaged position and a disengaged position. When the parking brake handle is in the disengaged position, the lawnmower control levers are permitted to operate the lawnmower drive system, and the lawnmower engine startup circuit is in an open condition in which the engine is unable to be started. When the parking brake handle is in the engaged position, the lawnmower wheels are substantially prevented from rotating, the control levers are locked in a neutral position, and the startup circuit is in a closed condition in which the engine is able to be started. Movement of the parking brake handle to the engaged position causes the control levers to move to the neutral position.
