Lawn mower height-adjust systems include three embodiments. Two permit the user to adjust the position of the deck relative to each wheel individually. The third permits the user to adjust the positions of all four wheels simultaneously, aided by a counterbalance system. A modification of the third embodiment is available to automatically bypass the height-adjust mechanism in the event an abnormally high load is placed on the deck. One of the two individual systems permits an operator to adjust the position of a respective wheel simply by removing a single nut and washer from an axle bolt. The second individual height-adjust system permits the operator to adjust the height of an individual wheel by using one hand, and without having to disassemble the mechanism. The system which adjusts all four wheels simultaneously links front and rear axle subassemblies with a connecting rod, and indexes all four wheels simultaneously through a release handle which is recessed in a cavity formed in the lawn mower deck. When the operator lifts the release handle, he or she may simultaneously grasp a portion of the deck with the same hand and easily raise or lower it to a desired position. A single unitary plastic deck is the foundation for each of the three height-adjust systems, thereby significantly reducing the cost otherwise incurred by manufacturing three separate types of lawn mowers.

An improved releasable handle assembly for power driven lawn and garden devices is disclosed. The improved handle assembly includes a 'handle to pivot pin' connection for releasably attaching the handle assembly to pivot pins. Coactive with the 'handle to pivot pin' connection is an improved 'handle to deck' latching system. The deck includes a pair of offset tower assemblies defining inclined forward and rearward handle positions. A latching mechanism is mounted to said handle assembly for telescopic movement thereon through a limited range of motion for releasably engaging said handle tower assemblies. An operator must disengage the latch mechanism from the handle tower to permit selective pivotal movement of the handle assembly to the opposite inclined position.

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.

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.
