It's an Oliver OC-6. They were first introduced in 1953 and used a Oliver 77 power train. Since a crawler would put more torque on the drivetrain, the transmission was based on the larger 88. The OC-6 was built in gauge widths of 32", 42", 60" and 68" center to center on tracks. They were tested at Nebraska in April 1954. It made a low gear pull of 6115pounds at 1.83 mph while producing 30.36 drawbar horsepower. If you need more information or parts visit cletrac.org.
