  • Air compressors like this ca. 1940 Ingersoll-Rand K-105 powered tools such as jackhammers, pavement breakers and small drills. This one produces 105 cubic feet of compressed air per minute.
  • Wagon drills like this one built by Ingersoll-Rand consisted of a drill powered by compressed air, mounted on a wheeled chassis for portability.
  • In the 1950s, air-powered crawlers replaced rubber tires as the preferred mounting for pneumatic drills. This 1964 Ingersoll-Rand CM2 Hydraboom Special, with an extendable boom, is an example.
  • This is the oldest known International Harvester crawler tractor, a 1928 10-20 TracTracTor prototype loaned to the Museum by National Director Mike Androvich.

  • This 1955 International Harvester 2T-75 prime mover and 2S-75 scraper was designed by Heil. I-H entered the scraper market by buying the Heil line in 1954. (Ron Wozniak photo)
