Disposable bag mounting and shutdown mechanism for rotary lawn mower

摘要

A rotary lawn mower is provided with a grass collection bag arrangement comprising a bag holder having a flexible skirt for supporting a disposable collection bag. The bag holder is mountable on a mounting plate facing rearwardly on the mower housing and close coupled to a grass discharge chute formed on the housing. The bag holder is retained on the mounting plate by a pivotally mounted lever engagable with the bag holder frame and operable in the release position to actuate an ignition grounding switch to ground the ignition system of the mower engine. The mower engine power takeoff shaft is coupled to a rotary blade which is mounted on a hub having a cylindrical brake drum fixed thereto. A spring coil brake band is disposed around the brake drum and pivotally mounted at one end to the mower housing and connected at the opposite end to a flexible cable which is connected to the bag holder retaining lever. Movement of the lever to the bag release position grounds the ignition circuit of the engine and engages the brake to arrest rotation of the mower blade. The bag holder is adapted to support conventional disposable trash collection bags and includes support members on the lower end of the skirt adapted to be mounted on the mower handle to form a closure supporting the collection bag when the bag is mounted on the mower.
