The grader unit is used for the accurate two-dimensional sizing of potatoes and onions through the use of rotary screens. Agitation and screen speed are adjustable to suit the variety and
conditions. A tuber ejection system can be added, which assists in removing any long varieties of potatoes and onions, which may become trapped in the screen thus preventing them from being cut by
the final pintle roller.
