Celebrating National Ag Day: Patents That Revolutionized Agriculture
National Ag Day is celebrated annually in March. It’s a day to recognize the groundbreaking innovations that have shaped modern agriculture. Patents have played a crucial role in fostering advancements in agricultural technology. Let’s take a closer look at some impactful agricultural patents that have revolutionized the industry.
Eli Whitney’s Cotton Gin: US Patent No. 72X (1794)
Eli Whitney, a notable innovator of his time, invented the cotton gin. The patent for this invention was issued on March 14, 1794. This simple yet effective machine separated cotton fibers from seeds, significantly reducing the labor required for cotton processing. Before the cotton gin, it took hours to produce a single pound of cotton. Whitney’s invention increased productivity, allowing one machine to produce up to 50 pounds of cleaned cotton in a day. This vastly outperformed manual methods. This new invention quickly revolutionized southern agriculture, making the cultivation of short-staple cotton an exceedingly profitable venture almost overnight. The cotton gin had profound economic and social impacts on the American South, including the start of the Civil War within the next 10 years.

Hiram Moore’s Combine Harvester: US Patent 9,793X (1835)
Nearly 100 years after the cotton gin, the first combine harvester emerged. Patented by Hiram Moore in 1835, it revolutionized the way crops were harvested. This machine combined three essential harvesting processes—reaping, threshing, and winnowing—into one efficient operation. Some sources say he exchanged letters with others citing his name for the machine to be the Thresher.
Early versions of the combine harvester were pulled by teams of 20 horses or mules and could harvest large fields in a fraction of the time it took manual labor. The combine harvester’s efficiency and productivity have made it a staple in modern agriculture, significantly reducing the manpower required for harvesting.
Agriculture Machine U.S. Patent No. 635,501
In 1899, Jacob J. A. Morath was granted a patent (U.S. Patent No. 635,501) for his agricultural machine. The invention includes a propulsion mechanism that plows the ground and severs plant roots, with vertical adjustment capability. The traction devices allowed the machine to travel over fields and roads, steering around curves or bends. Read more about the history of this machine in a past blog post.

John Deere’s Weed Seed Based Harvester
John Deere has been at the forefront of agricultural innovation for nearly two centuries. One of their recent patents, US11206763B2, introduces a harvester that includes a crop path along which crops are moved, a working member to interact with weed seeds moving along the crop path, and a controller. The controller receives data indicating forthcoming weed seeds and outputs control signals to control the working member based on the data1. This technology represents a significant leap forward in precision agriculture, improving efficiency, sustainability, and crop yields.
