Making the Grade: Caterpillar Auto Patrol

Rare 1933 Caterpillar Auto Patrol featured at company's 75th anniversary display.

When Don started working on the 1933 Caterpillar Auto Patrol No. 7, it only had one tire; the rest had rotted away. “It needed everything,” he says, “and it needed a lot of work.” The Auto Patrol’s 4-cylinder, 40 hp engine was also built by Caterpillar.
