Yellow Trail from Texas
The assault begins in Texas in May. By the time it is finished, five months later, the combine harvesters - hundreds of them - will have chewed their way north for nearly 2,000 miles to the Canadian prairies. The North American wheat harvest must be the biggest farming job in the world. In an hour, each combine can cut enough wheat to keep the average British family in bread for 40 years.
A BBC film team joined one of the harvest crews on their summer journey.
