Cyrus H. McCormick receives a U.S. patent for his mechanical reaper, a key breakthrough in mechanized grain harvesting that later underpinned large-scale harvesting equipment manufacturing.
In Grand Detour, Illinois, John Deere produces the first commercially successful self-scouring steel plow, helping prairie farmers plow sticky soils efficiently and accelerating Midwestern agricultural expansion.
McCormick receives a second U.S. patent covering improvements to the reaper, reflecting iterative engineering that helped move harvesting machines toward broader reliability and adoption.
McCormick relocates his reaper operation to Chicago, positioning production near rapidly growing Midwest grain markets and transportation networks—an important step in scaling farm-machinery manufacturing.
President Abraham Lincoln signs legislation establishing the U.S. Department of Agriculture, expanding federal capacity for agricultural statistics, research support, and dissemination of farming information.
Lincoln signs the Morrill Act, enabling states to fund colleges focused on agriculture and the mechanic arts—an institutional foundation for agricultural engineering education and innovation.
John Deere’s business is incorporated as Deere & Company, reflecting the maturation of a major farm-machinery firm during the industrial-era expansion of U.S. equipment manufacturing.
The Great Chicago Fire destroys much of Chicago, including portions of the McCormick reaper works, highlighting the vulnerability of concentrated industrial production and prompting rebuilding in a critical machinery hub.
Joseph Glidden receives a U.S. patent for a practical barbed-wire design, enabling mass-produced fencing that reshaped livestock management and accelerated enclosure of farmland and rangeland.
President Grover Cleveland signs the Hatch Act, providing federal support for agricultural experiment stations linked to land-grant colleges—boosting applied research relevant to farm practice and machinery use.
The Post Office Department launches the first Rural Free Delivery experiment, improving rural communication and supporting mail-order distribution channels important to farm supply access and machinery sales.
McCormick Harvesting Machine Company and Deering Harvester Company merge (with additional firms) to form International Harvester, consolidating manufacturing and distribution in the farm-machinery industry.
After experimental years, rural delivery becomes a permanent nationwide service, reinforcing infrastructure and market integration that supported rural modernization and equipment purchasing.
The Smith–Lever Act establishes cooperative extension work between USDA and land-grant institutions, scaling practical education on farm production, technology, and management—including mechanized methods.
The first major U.S. federal highway-aid law is signed, supporting improved rural roads (“post roads”)—a key enabler for moving heavy machinery, inputs, and crops as farms mechanized further.
Ford’s mass-produced Fordson tractor enters the market at a comparatively low price point, helping make general-purpose tractors accessible to more farmers and accelerating power mechanization on U.S. farms.
Fordson production and distribution expand in 1917–1918, demonstrating assembly-line methods applied to agricultural power equipment and influencing the broader tractor market.
