  • 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.
  • A crawler drill's mast can be set in a wide range of positions based on the angle of the hole to be drilled. The drifter travels down the mast to drill the hole.
  • 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 1949 International TD6 crawler tractor is not believed to have been of military origin, but the U. S. War Department ordered thousands of I-H crawlers during World War II.
  • c. 1945 International Harvester T9 crawler tractor with Bucyrus-Erie hydraulic loader. Bucyrus-Erie was a major supplier of attachments for I-H tractors until I-H bought the line in 1953.
  • 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)
  • This model wheel loader was built in the early 1940s by International Harvester to accompany a patent application. It was never pursued, and I-H instead affiliated with the Hough Payloader line.
  • C. 1920s Isaacson Iron Works pull scarifier. This machine was used by a paving company to break up the roadbed for finegrading. (Ron Wozniak pohoto)
  • This Isco TD-1120 tandem-axle end dump's carrying capacity of 21 cubic yards or 33.5 tons reflects how dense and heavy excavated material can be.
