In response to an interesting comment, I thought I'd post the short answer to a question I get from time to time... Why are old International Harvester trucks called corn binders?

It actually goes all the way back to when Cyrus McCormick invented the first successful reaper.  In Chicago in the late 1800's McCormick improved on his equipment to bind twine, which was commonly used in corn fields.  It was one of their most successful pieces of agricultural equipment and formed the basis of the early International Harvester Company in 1902.

The trucks came along shortly thereafter in 1907 with the "Auto Wagon".  Light line International Trucks were always primarily targeted to and sold to farmers - this link with their agricultural equipment and use in the field (often for actually binding corn), earned them their nickname "cornbinders" or "binders".
