摘要： A feed roll spike for mounting to a surface, i.e. the outer surface of a feed roller of a harvester head or a debarking machine. The feed roll spike comprises a substantially truncated cone shape base having a top side, a bottom side and an axis; and evenly-spaced identical projections extending upwardly from the top side of the base. The space between the projections defines channels.
