The Grumman G-164 Ag-Cat is a rugged agricultural biplane that became one of the most successful crop-dusting aircraft in American aviation history. First flown in 1957, the Ag-Cat was Grumman's entry into the civilian agricultural market, applying the company's legendary structural engineering from naval fighters to the demanding world of low-altitude aerial application. Built with a steel-tube fuselage and fabric-covered wings, the biplane configuration provided exceptional slow-flight handling and the ability to operate from short, unprepared strips adjacent to fields. The design proved so durable that Ag-Cats remained in production for over three decades, with more than 2,400 built across multiple variants powered by radial engines ranging from 220 to 600 horsepower. The type's wide-track landing gear, excellent visibility from the elevated cockpit, and ability to carry chemical loads up to 2,000 pounds made it ideal for agricultural operations across North America. Many Ag-Cats accumulated tens of thousands of flight hours in service, a testament to Grumman's "built like a tank" philosophy. While newer turbine-powered ag-planes have largely replaced it in commercial fleets, the Ag-Cat remains beloved among operators for its simplicity, reliability, and forgiving flight characteristics at the low speeds and altitudes where aerial application work happens. SkyMeter has tracked 6 flights across 3 airframes and 3 operators, with JACOBSON LUKE W the largest observed operator.
