Nut harvester with separating disks

A nut harvester, comprising:

• a power take off;
• a fan assembly;
• a hydraulic pump;
• a hydraulic motor;
• a crop product collection mechanism;
• an exit conveyor;
• a mechanical connection between the hydraulic motor and a roller assembly;
• and
• the roller assembly including:
• a first rotational shaft mounted to a frame, wherein the first rotational shaft coincides with a first rotational axis and includes a plurality of disks axially mounted thereon;
• a second rotational shaft mounted to the frame parallel to the first rotational shaft, wherein the second rotational shaft coincides with a second rotational axis and includes a plurality of disks axially mounted thereon;
• and
• the plurality of disks, each including:
• a non-circular unitary body;
• a hole extending through the body and defining a first rotational axis;
• a first segment of the body including a first outside perimeter and a first segment thickness;
• and
• a second segment of the body adjacent to a first face of the first segment, the second segment including a second outside perimeter smaller than the first outside perimeter and a second segment thickness greater than the first segment thickness;
• wherein:
• the plurality of disks are configured to cooperate with disks mounted adjacent along the first rotational shaft and disks mounted along the second rotational shaft, whereby a first axial gap and a second axial gap between cooperating adjacent disks along the first rotational shaft combine to equal the second segment thickness minus the first segment thickness, and a radial gap is defined by a distance between the first outside perimeter of disks mounted along the first rotational shaft and the second outside perimeter of cooperating disks mounted along the second rotational shaft,
• the first and second rotational shafts are separated by a radial spacing distance,
• a perimeter of the hole has four hole sides and the first and second outside perimeters have three disk sides, and
• the first outside perimeter has three apexes connected by three arcs and the second outside perimeter has three apexes connected by three arcs, wherein the arcs have a same radius that is based on a radius of a circle and the apexes of the first outside perimeter align with apexes of the second outside perimeter.
