Individual, ring-shaped wheel weights are provided as ballast for increasing the traction of a tractor. The weights are constructed to be mounted coaxially, one against the other, in numbers sufficient to supply the ballast desired. The first weight mounted is bolted to the outer face of the wheel disc and the weights added thereafter are secured in succession only to the adjacent previously mounted weight. The connection between the adjacent weights is effected by a pair of interengaged hook and shoulder connection parts in cooperation with a bolt which is inserted into and held by a nut in an opening formed by cooperating, U-shaped grooves in the adjacent weights. The hooks, shoulders and grooves are so disposed relative to each other that by tightening the nut on the bolt the hooks of the weight being mounted become tightly engaged with the shoulders of the adjacent mounted weight. |
