Abstract: A hollow wheel is rotatively mounted on a vehicle about an axis of rotation defining an acute angle with the vertical. This wheel comprises a first convex side wall having an outer face defining a circular and axially tapering tread centered on the axis of rotation, and a second side wall spaced apart from and connected to the first side wall to form the hollow wheel. A tube, centered on the axis of rotation, interconnects the first and second side walls to receive an axle. The tread is generally conical and presents a convex cross section. Preferably, the interconnected first and second side walls form a water-tight hollow body presenting buoyancy. The hollow wheel can be used on ground, water and snow.

Abstract: The present invention relates to a snowplow blade to be attached to a small all terrain vehicle. The snowplow blade comprises a lower portion constituted by a rubber sheet, the bottom edge of which is urged forwardly by a ground-engaging bar biased forwardly by springs. The rubber sheet and the ground engaging bars are free to yield rearwardly against the springs, when sufficient resistance is encountered. The invention also pertains to an attachment for connecting the snowplow blade to a vehicle. The attachment is constituted by a frame having a main point of connection with the vehicle at the rear end thereof, the front end of the frame being suspended from the chassis of the vehicle. Also described is a removable scraping edge mounted to the lower edge of the rubber sheet.
