On August 30, 1960, John Deere dealers from around the world converged on Dallas, Texas, for an unprecedented product showcase. Deere Day in Dallas, as the event was called, introduced the world to the "New Generation of Power", the company's first modern four-cylinder and six-cylinder tractors, during a day packed with high-tech presentations, live demonstrations, and a parking lot full of brand-new green and yellow machines. The line of tractors introduced that day was five years in the making, and the event itself took months to plan. Deere chose Dallas to host the event partly because it was home to facilities large enough to accommodate the 6,000 guests and the equipment they were all there to see. The Dallas Memorial Auditorium, the Texas State Fairgrounds Coliseum, the Cotton Bowl, and the Cotton Bowl parking lot were each the site of part of the event. During the event, a new John Deere tractor with a diamond-covered nameplate was displayed for all to see inside Neiman-Marcus, a popular Dallas-based department store.
