This machine was originally introduced as the "Caterpillar Diesel No. 12 Auto Patrol" in the summer of 1938, but was soon renamed as a "Motor Grader" just one year later.
Weighing in at 20,360 pounds, the No. 12 Auto Patrol featured a 12-foot blade, had six forward speeds and two reverse speeds. This machine, as well as other auto patrol models, was primarily used in the building of roads and snow removal.
The No. 12 Motor Grader has seen multiple advancements over the past 75 years. Caterpillar introduced articulated frames into its Motor Grader product line in 1973 with the 12G. The 12H increased productivity even further with a new electronically controlled eight-speed transmission and a redesigned cab providing operators with a better view when it was released in 1995.
The No. 12 Motor Grader is currently being produced at the North Little Rock Facility, Caterpillar Brasil Ltd. and Caterpillar Suzhou Company Ltd.
