It was founded in 1926 as Iseki Farm Implement Trading Co. (井関農具商会) in Matsuyama, Ehime, Japan. It was incorporated in 1936 as Iseki & Co.

Iseki began building tractors in 1961. Early models of the Iseki tractor were built under Porsche-Diesel's technology and design transfer contract. Its tractors have been and are sold worldwide under various brands: AGCO, Bolens, Challenger, Massey Ferguson and White. Some models sold in Japan have been built by Landini of Italy and by Massey Ferguson in France.

Early TYM tractors were based on Iseki's designs and used Iseki's expertise.

Iseki also has joint ventures with other companies, among them Dongfeng Motor.

Iseki have changed the way grass clippings are collected on their garden tractors. Unlike most machines where the grass is forced up over the transmission and other elements, the Iseki tractor has a system where the transmission is passed to the wheels by a series of chains, much like a rice paddy tractor.
