A wheel guard or skirt is disclosed for use with a wheel of a machine or appliance. The wheel guard is designed to push an obstruction such as a wire, cable or other debris away from the wheel as the machine is moved along a floor. The wheel guard includes a first base member, having first and second ends, a second base member, having first and second ends, an upstanding first end member positioned between the first ends of the first and second base members and an upstanding second end member positioned between the second ends of the first and second base members. The wheel guard is designed to push obstructions away from the wheel to prevent the wheel from running over the obstruction. The wheel guard may be of one-piece construction. |
