DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a lawn mower according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show a lawn mower according to an embodiment of the present invention. The lawn mower of this embodiment includes a rolling member 10 rolling on a ground surface, An operating member 30 having one end connected to the base frame 20 to transmit an external force and a blade provided at the rear of the base frame and sloping in the forward and backward directions And a cutter member 41 on which the cutter 41 is formed.

The rolling member 10 may be formed of a cylindrical body or a disk that can be rolled along the paper surface. In this embodiment, the rolling member 10 is made of a wheel.

The base frame 20 has a substantially U-shape with its front face opened and both front ends thereof are connected to the central axis of the rolling member 10 to support the rolling member 10 and the cutter member 41 . A cylindrical connecting portion 25 is formed at the rear end of the base frame 20 to connect the operating member 30. The connection portion 25 is provided with a plurality of bolts 26 for releasably fixing the operation member 30.

The operation member 30 is formed of a circular rod which can be pushed or pulled by the user's hand to move the base frame 20. The lower end of the operation member 30 is inserted into the connection portion 25 and fixed by the bolt 26. [ Although not shown in the drawings, the upper end of the operation member 30 may be provided with a handle that can be easily gripped by a user.

The cutter member 41 is substantially U-shaped, and upper ends of the cutter members 41 are fixed to the rear end of the base frame 20 by fastening means such as a bolt. The cutter member 41 is disposed behind the rolling member 10 so that the user moves forward together with the rolling member 10 and the base frame 20 by a pushing force of the operation member 30, Cut it. The cutter member 41 is preferably made of a special steel material which is heat-treated so as to have excellent abrasion resistance and strength.

The blade 41 formed at the front end of the lower surface of the cutter member 41 is formed so that both sides thereof are inclined in the forward and backward directions symmetrically with respect to each other so that the cutter member 41 can easily cut the root portion of the grass, Shaped as seen in FIG. 2, and has a sharp saw tooth shape as shown in FIG. When the blade 41 has a V-shaped tapered shape, the blade root 41 is sliced horizontally to the left and right when the blade 41 is in contact with the grass root, thereby improving cutting performance. In addition, if the blade 41 has a sawtooth shape, the cutting performance is further improved, so that the tired stem portion can be easily cut.

The lawn mower constructed as above operates as follows.

When the user holds the handle (not shown) at the top of the operation member 30 and pushes the operation member 30, the rolling member 10 rolls along the ground.
