Before rice harvest can begin, the fields must be drained. Once the fields are dry, state-of-the-art harvesters enter the fields to collect the perfectly ripe grain. Because quality is so important, these harvesters are designed to both gently and rapidly bring the grain in from the fields. Specialized tractors called bankout wagons come alongside, receiving the rice and delivering it to waiting trailers so the harvesters can continue without having to stop to unload.
