Abstract
A lawn mower capable of securing desired durability as well as suppressing a weight increase is provided. When prong portions on the periphery of a bottom disk are elastically deformed inward due to an external force applied thereto, the prong portions abut a cutting disk, so that the received external force is transferred to the cutting disk (that is, the external force is partially received by the cutting disk), and the displacement of the prong portions is restricted by the presence of the cutting disk.
