Once peanuts are dug from the ground, they are left in the field to dry before being combined (peanuts separated from the dug plant), graded, and prepared for market. Optimal conditions are when the peanuts sun-dry for a few days on top of the ground. This reduces the need and duration of mechanical drying with forced hot air ($$ propane $$).
A sun drenched field also creates dust storms which farmers had to endure before there were closed cabs. Here, Will Wofford of Houck Farms, dumps a load of peanuts into an open top tractor trailer which when full is driven to the peanut yard for grading and storage.
