摘要

The lawn mower (1) includes a cryogenic or cooling laser emitter (4) that outputs laser beams (5) to freeze the grass (2) and to make the grass easy to cut, and a height adjusting device (9) built in the lawn mower for setting the desired cutting height of the grass. A control unit is connected to the cryogenic or cooling laser emitter. A power source or power connection is provided for current supply.
