Inspired military engineers mounted cannons on track machines, which gave birth to the modern tank.

    Perrin Terra-Trac-Tor

    Though small, the Perrin Terra-Trac-Tor was anything but a weakling. The unique crawler was popular on the West Coast, and it turned out enough power to pull a one-bottom, 14-inch plow. It offered brakes, a PTO, and those distinctive 51⁄2-inch-wide steel tracks with deep cleats.
