The present invention relates to a mower, comprising a cutting mechanism, configured to execute a cutting operation; a machine body, wherein the machine body is connected with a side part protection which is located in the side of the cutting mechanism to establish a protection barrier in the side of the cutting mechanism; and a bottom protection, located below the cutting mechanism to establish a protection barrier below the cutting mechanism, wherein the bottom protection is provided with a grass inlet. According to the above mower, a human body is prevented from making contact with the cutting mechanism from the side direction of the cutting mechanism, the bottom protection can prevent the human body from making contact with the cutting mechanism from the lower side of the cutting mechanism, and the bottom protection is provided with a grass inlet, such that the cutting can be smoothly performed; due to the arrangement of the bottom protection, the side part protection and cutting mechanism can be set to approach to the outer side of the mower as much as possible, thereby realizing the cutting of the edge of a lawn, and meeting the cutting and safety requirements at the same time.
