Abstract: A system of drying agricultural products may include a spreader trailer system 100, a windrow construction system or cultivator system 200, a fluffer or aeration system 300, a drag bar system 400, a wide row maker system 500, a conveyer collection system 600 and a collection truck 640. A spreader trailer uses a plurality of chains or other belt drive systems 137 to move a plurality of flat conveyer bars 135 toward spinning breakup tines 157. The breakup tines allow the agricultural product to fall down upon a plurality of rotational plates 160 that disperse the product over an asphalt surface. Windrows over asphalt allow the product to heat at the sides of the windrow. The disclosed system prevents uneven drying and presents new efficiencies.
