    • A walk behind self-propelled crawler snowplow includes a snowplow mechanism (13) disposed on a front portion of a vehicle body, an engine (14) disposed on a longitudinal central portion of the vehicle body for driving the snowplow mechanism, a left crawler belt (11L) and a right crawler belt (11R) disposed on a left side and a right side, respectively, of the vehicle body, and left and right electric motors (21L, 21R) disposed on a rear portion of the vehicle body for driving the left and right crawler belts, respectively. With this arrangement, the crawler snowplow has a good weight balance such that the load or weight of the vehicle body is born evenly by the crawler belts. Since the snowplow mechanism and the crawler belts are driven separately by different power sources, the crawler snowplow can exhibit a good traveling performance regardless of the load exerted on the snowplow mechanism.

    • An overload prevention device has a first rotational member for driving engagement with an input shaft of an auger transmission of a snow removing machine, a second rotational member engaging the first rotational member for rotation therewith over a predetermined torque range and for rotation relative thereto when a predetermined torque is exceeded, and a movable member mounted adjacent to the first rotational member for undergoing movement to restrict a rotating angle of the second rotational member. A detector outputs a detection signal each time the detector detects movement of the movable member in a direction away from the first rotational member when protuberances of the movable member engage protrusions of the first rotational member responsive to relative rotation between the first and second rotational members. A control unit stops operation of the engine when the detector outputs the detection signal a preselected number of times within a preselected time period.
