Combines are machines used to harvest grain. As a farmer guides it through a wheat field, crops are pushed down and cut by its blades. The cuttings are collected and placed on a conveyor belt inside the combine, where a threshing drum shakes the cuttings to free the grain and send it into a tank below. The conveyor belt moves the unused straw through the combine and onto the field. When the grain tank is full, it is unloaded into a truck or trailer through a side chute.
John Deere began in 1837 as a company specializing in small tools, shovels and pitchforks. The business revolutionized farming later that same year when its founder made a saw blade into a plow. The company has grown from a small, made to order business into a worldwide conglomerate that is considered the cornerstone of the agricultural business.Learn more about Vehicles
