Each bin is lined with plastic to minimized damage to the apple from rubbing against the side of the bin. And depending on the variety of apple, bubble sheets are placed in the bottom of each bin. When the bin is full, the ticketer comes and staples a ticket to each bin. The picker is then handed a stub from the ticket identifying them as the person who picked this particular bin. Once the bin is ticketed, it can be hauled out of the orchard.
Tractor drivers have many jobs during harvest.
They unload bins from semi trucks at the orchard and move them into the orchard. During picking, they help pickers by moving partially-picked bins closer to where the picker is picking. And they haul the ticketed bins out to a landing area to be stacked. This must be done slowly so the apples do not bruise in the bin. There is one tractor driver who has the most important job.
