The design of the frame not only provides support for steady walking, but also protects other key components such as the engine and blades. For different types of lawn mowers, the structure and design of the frame may be different. For example, some small lawn mowers may use an integrated stamped or cast chassis as the frame. This chassis usually also has the function of the blade disc, thereby simplifying the overall structure, while larger lawn mowers may have a more complex load-bearing structure, similar to the frame of a vehicle. Its structural forms include side beam type, X-shaped frame, ladder frame, spine frame and integrated frame.
