ABSTRACT:
The snowblower of the present invention includes a novel housing structure having upwardly extending side cutter bars angling outwardly from the leading sides of the snowblower housing. Beneath the side cutter bars, the lower leading edges of the housing are angled upwardly and provided with pavement protecting skid shoes. The snowblower housing encloses rotatable snow blower fans provided with ice chopper bars which rotate with each fan and cut into the snow. Each snowblower fan is associated with a rotatable discharge spout which is mounted upon a turntable. A novel metallic and plastic bearing assembly is mounted upon the turntable to provide greaseless rotation of the discharge spout, and this bearing assembly is enclosed in a shielding unit to prevent snow and grit from reaching the turntable. All shafts within the snowblower which, through torque or tension, are subject to structural misalignment, are provided with floating oil seals to prevent shaft misalignment from rupturing the oil seal.
