  • Patent number: 4103383
    Abstract: A snow drag in which the snow moving member is a sector of a pneumatic semi-resilient tire carcass extending through an arc of about 120.degree.. A transverse section through the tire carcass is arcuate in shape with the outer edge being used as a snow drag and the interior of the carcass functioning as a scoop for gathering the snow. A handle is rigidly secured to the center of the inner edge of the tire carcass sector and radially extending and arcuate reinforcing members are mounted on the exterior and interior arcuate surfaces. These members are arranged in pairs with rivets interconnecting the two members of each pair and extending through the tire carcass. This arrangement permits the tire carcass to have a certain amount of resiliency while still retaining its overall general shape.
