ABSTRACT:
An adjustable mechanism for the spoke-carrying shaft of a harvesting machine for blueberries and other plants including a first shaft for receiving rotary motion, a second shaft offset from and parallel to the first shaft, harvesting spokes mounted in tiers on and projecting radially from the second shaft, a first screw adjustment for varying the distance between the first and second shafts to thereby vary the orbit of the second shaft, counterweight members mounted relative to the second shaft, second screw adjustments for varying the positions of the counterweight members to correspond with the adjusted position of the second shaft to thereby balance the second shaft in all adjusted positions thereof, with certain of the spokes having their outer ends inclined upwardly relative to the horizontal while other spokes have their outer ends inclined downwardly relative to the horizontal so that the projection of the outer ends of the spokes in a vertical direction provides relatively great vertical coverage of the plant being harvested, and mounting structure for varying the inclination of the spokes.
