A hook for use in a wood chipper having a winch including a winch line, the hook being intended for use in securing the winch line to a load of branches, brush or logs so that the load can pulled by the winch line toward a feed mechanism in the wood chipper. The cutter blades in the wood chipper are made of steel. The hook comprises a unitary structure. The material from which the hook is made is selected from the group consisting of tin, glass fiber reinforced polymer, carbon fiber reinforced polymer, wood, ceramic, zinc alloy, lead and combinations thereof. The unitary structure in one version of the invention has a head portion, a neck portion extending down from the head portion and at least one arm extending out from the bottom of the neck portion and curving upward and inward toward the direction of the neck portion. In another version of the invention the unitary structure has a back wall portion, a front wall portion having an upper portion and a lower portion spaced from the upper portion, a top wall portion having a pair of openings and a bottom portion. |
