POWER INTERMITTENT BRAKING DEVICE OF SNOW PLOW

PROBLEM TO BE SOLVED: To solve the problem wherein although a safety mechanism has been provided for stopping an engine when a driver leaves a driving position or sets a clutch lever free, the driver has to always hold an operating lever, resulting in increasing the fatigue of the driver, and when the clutch is released due to an unexpected cause, the clutch levers are suddenly returned to the release position by energization of a return spring and the like, the levers strike on the hand or fingers to be disadvantageous in use. SOLUTION: The clutch lever and the clutch part are connected to each other by interposition of a cam device, the ratio of the operating load and the operation stroke is varied to relax a sudden return of the clutch lever and also when the driver leaves, an electric motor automatically returns only the clutch lever to precede to a substantially release position by the operation of a sensor, and the power of clutch is cut with a designated time difference.
