Summary:To solve the problem of users intentionally disabling from the start the dead-man control function, which is a standard safety device for small walk-behind snow removers, because it interferes with work.SOLUTION: Contrary to a dead-man control, a dead-man switch continues to operate for a prescribed period of time or more while a snow remover is in operation, a warning alarm notifying that the dead-man control is disabled is sounded depending on the presence state of an operator at that time. Alternatively, a clutch is disengaged to shut off power to a driving device.SELECTED DRAWING: Figure 9 【課題】小型歩行型除雪機に標準の安全装置であるデッドマン制御には当初からユーザーが、作業に邪魔になる、と故意にこの機能を殺してしまう（デッドマン無効化）問題があった。【解決手段】除雪機動作中、デッドマン制御とは逆に、デッドマンスイッチが一定時間以上動作し続けたとき、その時の操縦者の駐在状態によって、デッドマン制御無効化の警告警報を発するようにし、又はクラッチを断させ駆動装置への動力を遮断させるようにした。【選択図】図９
