Generally, the above-mentioned grass collecting section structure of the lawn mower has a structure in which the wind conveyed from the duct is blown to the grass collecting container side far from the grass lawn carry-in port to collect grass far from the grass lawn carry-in port. So that you can start filling the grass from the container,
The clogging gradually shifts to the grass lawn carry-in side, and finally the grass collection container near the grass lawn carry-in entrance is packed. In such a grass collection part structure of a lawn mower, in the case of dry grass, the grass is collected in the grass container smoothly without adhering to the grass cutting prevention net for the wind vent. Although the exhausted air will smoothly escape from the wind vent for ventilation through the grass clippings preventive net, moist grass and wet grass tend to adhere to the grass clippings preventive net. , When the amount of adhesion to the grass clippings prevention net part on the side of the grass collection container far from the grass clippings entrance increases, the exhaust air blows to the grass clippings prevention net on the grass collection container side next to the grass clippings prevention net. Since the grass is not yet completely filled in the grass collection container far from the grass lawn inlet, it is discharged from the part, but there is the inconvenience that the grass lawn is packed in the grass container near the grass lawn inlet. there were. Therefore, it is possible to replace the grass clipping prevention net in the cover with a mesh having a mesh that is difficult for the grass to catch when moist grass or wet grass is collected, but in such a case, However, there is an inconvenience that the replacement work of the net is troublesome and management such as storage is required. The present invention, by simply improving the structure of the grass clippings prevention net, prevents clogging of the grass clippings prevention net when moistening grass or wet grass clippings is taken, and the grass clippings are collected in the grass container. The purpose is to be able to pack well.

[0004]

To achieve the above object, the present invention is characterized in that a net portion of a lawn for preventing blown grass blown by the air conveyed from the duct is first fitted to the net portion. The point is that an auxiliary net for changing the mesh size, which is changed to a large or small size, is provided so as to be freely switchable between the operating state and the non-operating state.

[0005]

As shown in FIG. 1, when collecting dried grass, an auxiliary net 7 for changing the mesh is provided to prevent blowing of grass on the grass container B ₁ side far from the grass-carrying-in port 4. The grass is collected by switching to the operating state in which the net portion 6a is located on the front surface. Then, when collecting wet grass or wet grass, the auxiliary net 7 for changing the mesh is slid to the other side to switch it to the inoperative state, and the grass collecting container far from the grass carry-in port 4 The mesh of the cut grass blowing prevention net portion 6a on the B ₁ side is changed to a large mesh that does not cause clogging of the soup even if the grass is attached, so that clogging can be suppressed. Further, the work is periodically interrupted, the auxiliary net 7 for changing the mesh pattern is switched between the working state and the non-working state, and the grass clippings attached to the net portion 6a are wiped off to prevent clogging. Measure

[0006]

As a result of the above construction, an auxiliary net for changing the mesh can be easily provided on the front surface or the rear surface of the grass clipping prevention net portion so as to be switchable between the operating state and the non-operating state.
With an inexpensive structure, and without the need for troublesome net replacement work, it is possible to satisfactorily pack wet grass lawn or wet grass lawn in the grass collection bag in sequence.
