ABSTRACT:
A traction wheel has a pair of axially spaced apart annular rims presenting ground engagement surfaces which are inclined radially and axially inwardly toward one another to form the ground into a mound on which the wheel rides. A series of wedge-shaped lugs span the rims in circumferentially spaced apart relation. One of the inclined sides of several of the lugs extends radially inwardly to serve as a spoke for the rim. Each lug is generally V-shaped with an apex directed radially outwardly. An opening is formed through the apex both to increase traction and to dissipate any vacuum between the lug and ground.
