INSIDE A COMBINE HARVESTER
This specialist machine is a farmer’s go-to vehicle for harvesting crops
WORDS AILSA HARVEY
The hard outer shell, or chaff, is removed from the grain during winnowing
Wheat, barley, soy and rye are crops commonly grown by farmers, but the grains you buy in the shops and the products that contain them are only a small part of the plant grown. The edible parts of the plants are the seeds, and to collect them, three processes are required: reaping, threshing and winnowing. All three are usually carried out by combine harvesters.
