Upper ends of four c-shaped members attached to an upper plate on the upper end of the attachment. Opposite lower ends of each of the four spaced apart c-shaped members are flattened on upper and lower surfaces into a point. A lower plate is secured to the upper surfaces of the lower ends of the c-shaped members to form the front edge. Support bars secure between adjacent c-shaped members and openings are provided in the c-shaped members to reduce weight while maintaining strength.
