For farmers, the world of hay changed hugely in 1872 when Charles Withington invented the first successful mechanical hay baler with a knotter.

That machine was commercialized by Cyrus McCormick two years later. Because it bound hay into compact bales, it significantly improved hay transportation and storage, and doubtless many readers will remember hefting those small bales and piling them onto hayracks in their youth.

The world of hay changed hugely once more with the invention of the round baler. But who first invented the round baler – Depends on who you ask. And what you call it.

In terms of round balers, five possibilities exist: Ummo Luebben in 1910; John M. Wolf in 1928; Allis-Chalmers in 1947 with their Roto-Baler; Wesley Buchele and Virgil Haverdink in 1966; and Gary Vermeer in 1971.

Ummo Luebben

The idea for the first round baler emanated from the Luebben family of Sutton, Nebraska. According to Katy Moore in “Fame on the Luebben Farm” in Midwest Messenger, “It started with a stove and some piles of straw. In the late 1800s, when harsh winters meant low fuel supplies, Melchior and Ummo Luebben, and their father Hugo, realized that the straw bundles they used as emergency fuel in the family’s stove heater were inefficient and slow to produce by hand. They began experimenting – building machinery that would roll the hay into a round bundle, perfect for burning.”
