ABSTRACT:
A device is disclosed, for use with a snow blower being of the type having an auger, and allow it to operate while moving backwards. The device principally consists of a concave blade mounted on a snow blower, which pivots between an operative position where the blade extends close to ground and the concave surface of the blade extends in front of the auger in such a way that the blade scrapes the snow and directs it towards the auger when the snow blower is lifted up to let the snow pass under it and moves backwards, and an inoperative position where the blade is raised to a height sufficient to let the snow reach the auger when the snow blower moves forwards. A snow blower equipped with a device as defined above, for operating while moving backwards, is also disclosed as well as a method for blowing snow with a snow blower equipped with that device. Although the device has been designed to fit on a removable snow blower mounted on a motorized vehicle, it could be adapted to any type of snow blower having an auger.
