EIGHTY YEARS AFTER LAUNCHING OUR FIRST MOTOR GRADER, WE’RE INTRODUCING THE M SERIES 3
Eighty years ago, Caterpillar introduced its first diesel motor grader, the Diesel Auto Patrol, which provided vastly improved fuel economy, saving customers significant operating costs. The engine was unrivaled in performance, durability and longevity. Throughout the years, Caterpillar continued with new Cat® products and innovations, including:
- Tandem rear tires, introduced in 1934, allowed drive tires to float over bumps without affecting the grade.
- The Diesel No. 12, a line introduced in 1938 that still exists today.
