ABSTRACT:
A replaceable pick-up tooth assembly for a crop pick-up comprises a plurality of pick-up teeth integrally molded to and with a substantially C-shaped flexible mounting unit. The pick-up teeth have a greater height dimension in the direction of rotation of the raking pick-up, and taper in height dimension from a base end at the mounting unit and a tip opposite the base end. The thickness of the teeth in the lateral direction perpendicular to the direction of rotation is much smaller than the height dimension at the base end. This provides added strength in the direction of rotation yet permits flexibility in the lateral direction along the axis of rotation. The pick-up teeth rotate in a plane perpendicular to the axis of rotation and parallel to the direction of rotation, and are concave in the direction of rotation with a large radius of curvature to provide added efficiency and accuracy in pushing up crops. The C-shaped mounting unit snaps onto a mounting bar of a crop pick-up.
