PROBLEM TO BE SOLVED: To provide a grass mower which has durability and can effectively prevent entanglement of cut grass. ! SOLUTION: An entanglement preventing blade 42 whose knife edge line is extended in the rotating direction of a rotary blade 20 is swingably fitted to the side face of a joint member 13 of a grass mower to a handlebar shaft 10, and the knife edge part is brought into sliding contact with the board surface of the rotary blade 20. Even when the rotary blade 20 is rotated with a large amount of cut gass put on the board surface, the entanglement preventing blade 42 is swung by pushing of cut grass from the rear in the rotating direction so that the cut grass on the board surface can be swept away. !
