If you thumb though old farm literature sales brochures from the late 1930s through the 1940s, what’s most striking is that machinery companies offered plows and other tillage equipment for both horse-drawn and tractor-drawn applications at the same time. Name the brand — IH, John Deere, Allis-Chalmers. They were still offering new horse-drawn tools even though they were also promoting tractors and tractor-pulled implements in the same brochure.

The three-bottom moldboard plow pictured here from the mid-20th century was advertised as a tractor-drawn model. Note it’s on rubber and equipped with a hydraulic cylinder to lift and lower the plow.

A few months ago, Indiana Prairie Farmer featured an innovative sickle sharpener that clamped to the steel wheel of a mowing machine. It allowed industrious farmers of the day to make repairs in the field without returning to the barn to use an anvil and/or vise.

John Hoffman, Bedford, Ind., correctly responded that this unique sickle-section sharpener was made by International Harvester, which often sold equipment under the name McCormick-Deering. The company was half of the forerunner of today’s Case IH, with J.I. Case contributing the other half to the name.

Congratulations, John! Keep those responses coming!
