Not to split hairs but this is actually called a "drill" named after the feed auger in the seed box which meters out the seeds into the seed tubes, dropped behind furrows cut by sets of disks mounted along the bottom side. It's a deluxe model designed to also fertilize and plant in one pass.

A combine is a harvesting machine which combines the previously separate farm practices of scything (cutting), threshing (beating the grain until it separates from the chaff), and winnowing (blowing air through the threshed grain and chaff to separate the components by their differing weights).

I do see the confusion and the logic in your statement, but I'm a farmer and a history buff. Sorry if I burst your bubble.
