PROBLEM TO BE SOLVED: To provide a rotary snowplow which is for use in clearing away snow, relatively small in size, and prevented from clogging with snow due to stopping of a snow-removing device. SOLUTION: The snowplow includes a prime mover 2, a traveling pump 3, a traveling motor 4, a traveling device 5, a swash plate control device 6, a snow-removing pump 7, a snow-removing motor 8, the snow-removing device 9, and a relief valve 10. The snowplow is comprised of a vehicle speed control device 11 which decreases the vehicle speed by returning a swash plate 12 of the traveling pump 3 in proportion to the load of the snow-removing device 9. Thus the speed of the snowplow is automatically controlled to an optimum value corresponding to the load of the snow-removing device. COPYRIGHT: (C)2004,JPO
