From the above link, here's the 1970 Kubota "dream" tractor.
In 1970, the year that Kubota reached its 80th anniversary, the Japan World Exposition was held for 6 months starting in March at Senrikyuryo, Suita City, Osaka Prefecture. The company’s theme for its dedicated Kubota Pavilion was “Abundant Crops.”
The “Dream Tractor” which was exhibited in the pavilion was a concentration of the most sophisticated technologies, and the excellent functionality, comfort and easy usability that it offered are still being put to use in products today.
In addition, 1970 was also the year that the Shiga Branch Plant of the Vinyl Pipe plant was established in Kose-cho, Koka-gun, Shiga Prefecture, for the production of FRP bathtubs and septic tanks. The “Kubota Trane Co., Ltd.” was also established this year, in a joint venture with the specialized air conditioning manufacturer Trane Inc. from the United States.
