John Deere had manufactured articulated 8010 and 8020 models from 1959 to 1964. At the end of the 1960s, it decided to return once again to the large tractor market. Development of its own models was started, but in the meantime, it made an agreement to market a hundred Wagner tractors under the John Deere name. Wagner had been one of the first to start manufacturing articulated tractors in 1954 and initially succeeded well. The WA series was introduced in 1961, but during the 1960s, Steiger and Versatile emerged as the market leaders in the industry. Wagner, which was in financial difficulties, made an agreement with Deere that prohibited it from competing with Deere for five years. Thus, the story of the yellow Wagners ended with the short-lived contract period.

The WA-14 and WA-17 were equipped with 14-liter Cummins engines. In the more powerful model, the engine was turbocharged. The transmission was a mechanical 10+2, and the clutch was a dry 2-plate type. Air brakes affected all wheels.
