Snow blowing machine
摘要:
A snow blowing machine is disclosed, in which collection and throwing of snow is effected by an auger and blower assembly rotating at high speed and which is in direct engagement with the ground, the auger and blower assembly having blades edged with an antifriction material which reduces the frictional engagement of the auger and blade assembly with the ground, the residual friction providing the motive force for moving the snow blowing machine across the ground, thus eliminating the requirement for a separate drive for that purpose, and also eliminating a separate drive to the blower.
