Case IH is a global agricultural machinery powerhouse formed by the merger of J.I. Case and International Harvester. Renowned for the revolutionary Axial-Flow, Magnum, Quadtrac, and Steiger heavy row-crop tractors.
Historical milestones, founding origins, and technological breakthroughs.
Case IH represents the fusion of two titans of American agricultural history: the J.I. Case Threshing Machine Company (established in 1842 in Racine, Wisconsin) and Cyrus McCormick’s International Harvester Company (founded in 1831). In 1985, Tenneco acquired International Harvester’s agricultural machinery assets and combined them with Case, creating Case IH and uniting IH’s legendary diesel engineering and Axial-Flow harvesting technology with Case’s structural strength.
In 1987, Case IH launched the revolutionary Magnum 7100 Series—the first tractor developed entirely under the merged banner—which established new standards for full PowerShift transmissions, operator visibility, and heavy row-crop reliability. In 1996, Case IH changed heavy primary tillage forever with the introduction of the Steiger Quadtrac: four independently pivoting positive-drive rubber tracks that virtually eliminated soil compaction while efficiently transmitting over 600 engine horsepower.
Four separate rubber track modules pivoting 26 degrees to maintain ground contact on uneven terrain.
Clutchless gear shifting across all 18 or 19 forward ratios under maximum drawbar pull.
Gentle single-rotor crop separation reducing grain damage and increasing throughput.
Cloud-connected fleet management delivering 2-way agronomic file transfer and remote display viewing.
Jerome Increase Case starts manufacturing threshing machines in Racine, Wisconsin.
International Harvester unveils the first all-purpose tricycle row-crop tractor.
Tenneco combines J.I. Case and International Harvester agriculture into Case IH.
Debuts 18-speed full PowerShift and forward-sloping hood row-crop architecture.
Introduces the world's first 4-track articulated heavy agricultural tractor.
Unveils 778 peak horsepower heavy draft flagship powered by 16L twin-stage turbo diesel.
