Corn Picker Makes a Hard Job Easier

The Overby brothers’ corn picker made a hard job much easier.

More than 100 years ago, corn, while it had its advantages as feed, was difficult to do much with on a large scale. With the advent of the husker-shredder in the 1890s, corn could be cut by hand in the field, taken to the farmyard and hand-fed into the husker-shredder.

There, ears were snapped off, fed through husking rolls and elevated into a waiting wagon. Cornstalks could be chopped at the same time for use as bedding or fodder.

When the corn binder came on the scene just before 1900, the process became a bit easier. Cornstalks could be arranged in bundles, stacked in shocks in the field (like oats) and left to dry. Later, the shocks were taken to the barn to run through the husker-shredder. That sometimes meant chopping the butts of the shocks out of the ice. Surely there was a better way!

Putting their heads together

Some years before Wilbur and Orville Wright got off the ground, so to speak, the Overby brothers — John and Theodore — decided there had to be a better way to harvest corn. The brothers, who lived near Brentford, S.D., had less than 16 years of formal education between them. Starting with a new pair of binder wheels (dating their invention to 1895 or later), they built a corn picker. Family descendants set the picker’s completion date in 1904.

Like the Wrights, the Overbys did a lot of cutting and fitting and refitting — by hand. The brothers did not acquire a machine shop until 1913, when they ordered one (complete with a 6 hp Economy gas engine, which they used as a prime mover) from Sears, Roebuck & Co. Their foundry and that original machine shop are now on display at Historic Prairie Village in Madison, S.D., courtesy of the Overby family.

The Overby brothers had to be pretty determined, as all 79 castings used on their machine were made in Minneapolis, some 270 miles east. One wonders who made the patterns. And how did they compute shrinkage in the finished castings? It is easy to imagine many letters to and fro on this project. Some of the castings — like the gearing that runs the wagon elevator — are fairly complex. How were ratios established with no benchmarks to go by? The brothers also had to figure out a differential, so both wheels could furnish power and still turn at the end of the field. (This mechanism is somewhat like that employed on the early side-delivery rakes many of us used in our younger days.)
