This is a wonderful story from the home front of WWII. The gumption of the American farmer, the strength of industry, and the inventive nature of government to solve a big problem. That issue? The largest wheat crop in the history of the United States was coming in and there wasn't enough men or machines to properly harvest it. 

The answer? The Massey-Harris Harvest Brigade. This armada of 500 brand new combines swept from Texas to the Dakotas, nearly into Canada harvesting while a second team worked the fields of California and the Pacific Northwest. The relentless work and coordination resulted in a population of allied countries that were fed and armies that marched on full stomachs. 

A perhaps long forgotten story of horsepower, work power, and patriotism, enjoy this telling of a tale that should make your heart swell.
