Abstract:
A pine straw rake for raking pine straw from the base of an obstacle, comprising:two square drives in an offset and parallel orientation with respect to each other, the square drives including: a first sprocket; a second sprocket; a third sprocket in a geometric and planar arrangement with the first and second sprockets; and a roller chain wrapped around the partial circumferences of the sprockets, wherein the square drives are angled with respect to a forward direction of the pine straw rake, so that the square drives are in a non-parallel orientation with the forward direction; a plurality of rake bars connected to respective points on each of the roller chains, wherein the rake bars are connected to each of the square drives at an angle of less than ninety degrees; and a plurality of rake teeth connected to each of the rake bars, wherein the rake bars are adapted to move around the outer edge of the drives so that the rake teeth can move downward in close proximity of the obstacle along a lower edge of the square drives so that the rake teeth can move the pine straw from the obstacle, in a direction non-parallel to the forward direction.
