The International Harvester 786, 886, 986, and 1086 tractors represent a significant chapter in the history of agricultural machinery. These models, widely known as the "806 series," were produced by International Harvester from 1963 to 1981. They were renowned for their robust construction, powerful engines, and versatile capabilities, becoming staples on farms across North America and other parts of the world. Their popularity stemmed from their ability to handle a diverse range of tasks, from plowing and disking to harvesting crops and hauling heavy loads. The models were distinguished by their diesel engines, ranging in power from 80 to 140 horsepower, providing ample strength for tackling demanding agricultural chores. The 806 series tractors were notable for their innovative features, such as the "Live PTO" (Power Take-Off), which allowed implements to be powered independently of the engine's speed. Their hydraulic systems were recognized for their efficiency and reliability, facilitating smooth operation of various implements. Throughout their production run, these tractors underwent numerous updates and refinements, including improvements to their transmissions, hydraulic systems, and cabs. The 806 series has solidified its place as a classic in agricultural history, and its reputation for dependability and performance continues to be respected by farmers and collectors alike. The availability of detailed service manuals, such as the WSM (Workshop Service Manual) for these models allows owners to maintain and repair their tractors effectively, ensuring their continued operation for years to come.
