Lawn Mower With Adjustable Base Frame

摘要

The lawn mower has a base member that provides easy and flexible configuration of protection frames so that the blades are well protected from damage and the height of the lawn can be easily controlled. The base member contains a connection piece where each of the connection piece's lateral edges is configured with a notch, allowing the configuration of the base member onto a blade assembly in two perpendicular orientations. The base member also contains front and back tubes for detachably configuring protection frames adjustable to cover the revolving range of the blades. Wheels are then rotatably configured on the protection frames so that the lawn mower can freely and effortlessly move around the lawn.
