It was a steam-powered logging skidder, or cable winch. Ground vehicles such as a skidder or forwarder can pull, carry, or shovel the logs. In 1974, FMC used the M113's drivetrain as a platform for a tracked log skidder. One popular brand was the Clyde Skidder, built by Clyde Ironworks in Duluth, Minnesota. Weyerhaeuser No.3 Lidgerwood Tower Skidder moved to Roots of Motive Power Museum, Willits, CA. Nokian forestry tyres include the Skidder and Cut-To-Length model lines.
