Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a reel-type lawn mowing cutter and a motor for driving the cutter, and also covers the front, upper and lateral sides of the cutter to cut grass. This invention relates to a walk-behind lawn mower equipped with a cover that prevents water from scattering.

[Prior art]

Conventionally, in the walk-behind lawn mower described above, the cut grass is discharged onto the ground.

[Problem that the invention attempts to solve]

Therefore, when collecting the cut grass, it is necessary to collect the grass scattered over a wide area, which is time-consuming.

The purpose of the present invention is to make it possible to easily collect cut grass, and to obtain a configuration that is advantageous both in terms of operation and structure, and to enable the work to be carried out advantageously.

[Means to solve the problem]

The present invention provides the walk-behind lawn mower described above, in which the prime mover is disposed outside the cover, the cutter is disposed at the front end inside the cover, and the cutter is disposed at the front end of the mower for storing cut grass. box-shaped container,
The rear end side of the cover is equipped so that it can be inserted and removed from the rear of the machine, and the front opening of the box-shaped container is placed close to the cutter when inserted into the cover. The functions and effects are as follows.

[Effect]

According to the above configuration, since the prime mover is disposed outside the cover, the inside of the cover is formed into a hollow shape, and a box-shaped container can be disposed therein. In other words, by simply forming the container into a box shape into which the cut grass can be dropped, the front opening of the container is placed close to the cutter, and together with the guiding action of the cover to prevent scattering, most of the cut grass falls into the container. This allows you to work while storing the cut grass so that it does not remain after mowing or scatter into the surrounding area. Moreover, since the container can be inserted into and removed from the cover, for example, by adding a simple structure such as a receiving rail to the cover, the container can be removed or installed by simply inserting and removing the container. can.

Furthermore, by arranging the front end of the cutter within the cover, even if there is an obstacle such as a wall in front of the machine, it is possible to move the cutter as close to the obstacle as possible to avoid leaving uncut areas near the obstacle. becomes.

[Effect of idea]

Therefore, the collected grass can be easily collected by simply taking out the container from inside the cover, and the container can also be easily attached and removed, making the work more efficient in terms of collecting the grass. Ta. In addition, the space within the cover can be used as a recovery section, making the lawn mower more compact as a whole, and the structure is relatively simple and inexpensive both in terms of the container itself and the container attachment structure.

Furthermore, even when working by moving the machine forward toward a wall in a direction that intersects the sidewalk, for example, mowing the lawn as close to the wall as possible while preventing the grass from scattering or falling on the sidewalk or after mowing. so that cleaning of sidewalks and after mowing is not required, and
You can work advantageously by reducing the amount of manual cutting along the wall.
