By using this weeding machine, it is possible to efficiently cut the vegetation at the site to be weeded.

例えば、除草対象箇所が変電所等の広大な敷地の場合には、運転席を有するボディと、ボディを走行可能に支持する前輪及び後輪と、ボディの下部に回転自在に設けられる刈刃と、前輪、後輪、及び刈刃の駆動源とを備えた乗用タイプの除草機を使用し、作業者が運転席に座った状態で除草機を走行させながら刈刃を回転駆動させることにより、除草対象箇所の草木を刈り取ることができる。 For example, in the case where the site to be weeded is a large site such as a substation, a body having a driver's seat, front and rear wheels that support the body to be able to travel, and a cutting blade that is rotatably provided at the lower part of the body By using a riding type weeder equipped with a front wheel, a rear wheel, and a cutting blade drive source, by rotating the cutting blade while driving the weeder with the operator sitting in the driver's seat, It is possible to mow the vegetation at the site to be weeded.

ところで、上記のような構成の乗用タイプの除草機にあっては、除草対象箇所の地面上にバラス（砂利）が敷き詰められている場合に、バラスに刈刃が当たってバラスが周囲に飛散する虞があるため、使用可能な除草対象箇所が制限されてしまう。 By the way, in the riding type weeder configured as described above, when the ballast (gravel) is spread on the ground of the weeding target location, the blade hits the ballast and the ballast scatters around. Since there exists a possibility, the weeding object location which can be used will be restrict | limited.

一方、上記のようなバラスの飛散の問題に対処するため、特許文献１には、ボディに、ボディの周囲を囲むように保護カバーを取り付け、保護カバーで飛散するバラスを受け止めることにより、バラスが除草機の外方に飛散するのを防止するように構成した乗用タイプの除草機が提案されている。
特開２００３−１６４２１１号公報 On the other hand, in order to cope with the above-described problem of ballast scattering, Patent Document 1 discloses that a ballast is formed by attaching a protective cover to the body so as to surround the periphery of the body and catching the ballast scattered by the protective cover. A passenger type weeder configured to prevent the weeder from splashing outside has been proposed.
