Abstract
A self-propelled, walk-behind snowblower includes a pair of deadman control levers respectively pivotally mounted on a pair of handle bars of a guide handle structure. The levers are each spring biased to a normally released position and manually movable to an active position. A switch element is mounted for movement with each lever and completes an ignition circuit by engaging the associated handle bar when the lever is moved to its active position. The ignition circuit is also completed when a further interlock switch is closed by placing a collector-impeller control lever in a drive-disengage position.
