Abstract: A method and apparatus for mounting a protective flap assembly to the deck housing of a lawn and garden device is disclosed. The deck housing includes a horizontal support member having an open end and a closed end at opposite lateral edges thereof. The properties flap assembly has an upper socket portion adapted to surroundingly capture the support member upon inward sliding insertion onto the open end thereof. A lower portion of the protective flap assembly extends downwardly toward the ground. The support member is adapted to inhibit removal of the flap assembly following installation on the deck housing.

Abstract: An electro-mechanical interlock and module system for an electrically powered device such as a cordless, electric lawn mower that includes a normally open interlock switch for controlling the enabling of the power circuit for the lawn mower. A key member is adapted for insertion into a specially configured opening in the mower housing to actuate and close the interlock switch. With the interlock switch closed, energization of the motor is controlled by a separate handle-mounted ON/OFF switch in a conventional manner. In addition, a modular assembly technique is disclosed which facilitates ease of manufacturing while assuring proper alignment between the various components of the interlock system.
