How will a farmer know that the peanuts are ready for harvest?

When the leaves of the plants turn yellow, they are pulled out of the ground. When the plant has matured and the peanuts are ready for harvest, the farmer waits until the soil is not too wet or too dry before digging. When conditions are right, he or she drives a digger up and down the green rows of peanut plants. The digger pulls up the plant, gently shakes off any lingering soil, rotates the plant and lays it back down in a “windrow”—with peanuts up and leaves down.

Peanuts contain 25 to 50 percent moisture when first dug and are dried to 10 percent or less so they can be stored. They are usually left in windrows for two or three days to cure, or dry, before the next step.

After drying in the field, a combine separates the peanuts from the vines, placing the peanuts into a hopper on the top of the machine and depositing the vines back in the field. Peanut vines can be left in the field to nourish the soil or be used as nutritious livestock feed. Freshly combined peanuts are then placed into peanut wagons for further curing with forced warm air circulating through the wagon.
