Abstract
An agricultural article sizer with a frame assembly and a plurality of elongate rollers on the frame assembly with substantially parallel lengthwise axes and through which agricultural articles are advanced and separated by size. First and second of the rollers have first and second axes and first and second peripheral surfaces. A third roller has a third peripheral surface and a third axis between the first and second axes along a conveying direction. The third roller is movable selectively relative to the first roller to change a spacing between the third axis and a plane containing the first and second axes to thereby change a dimension of a gap between the first and third peripheral surfaces to thereby allow passage through the gap of different selected ranges of agricultural article size.

An agricultural article sizer comprising:
- a frame assembly;
- and
- a plurality of elongate rollers on the frame assembly with substantially parallel lengthwise axes and through which agricultural articles are:
- a) advanced in a conveying direction transverse to the roller axes;
- and b) separated by size,
- the plurality of rollers comprising first and second rollers with first and second axes and first and second peripheral surfaces and a third roller with a third peripheral surface and a third axis between the first and second axes along the conveying direction,
- the third roller movable selectively relative to the first roller to change a spacing between the third axis and a plane containing the first and second axes to thereby change a dimension of a gap between the first and third peripheral surfaces to thereby allow passage through the gap of different selected ranges of agricultural article size to facilitate sorting of different sizes of agricultural articles.
