has a substantially flat horizontal bottom surface 20 extending from a non continuous front edge 22 of the head to a bottom rear edge 24 a substantially flat vertical rear surface 26 extends upwardly from the rear edge 24 to a top rear edge 28 of the head a substantially horizontal solid top surface portion 30 extends forwardly from the top rear edge 28 to a continuously angled portion 32 that extends from an end 34 of the top surface portion 30 to the front edge 22 the top surface portion 30 is substantially parallel to the bottom surface 20 in addition the head 12 includes substantially vertical solid side surfaces 36 that extend from the bottom surface 20 to the top surface portion 30 and the angled portion 32 and extends from the front edge 22 to the rear surface 26 only one side surface is visible in fig2 it being understood that the opposite side surface is identical to the surface 36 that is visible in fig2 with reference to fig3 the head 12 includes a plurality of integrally formed tines 40 the tines 40 are formed by creating spaced gaps or slots 42 in the head 12 that extend from the front edge 22 toward the rear surface 26 and from the continuously angled portion 32 to the bottom surface 20 the gaps 42 stop short of the end 34 of the top surface portion 30 so that there is a section 44 of the angled portion 32 between the ends of the gaps 42 and the.
