The GP was originally designated the Model C, the name was changed due to a similarity to the existing D, plus the "General Purpose" name was a marketing ploy to keep in line with International's new "Farmall". The GP was designed as a row crop tractor, with the fixed front axle straddling three rows. Several versions of the GP were made. The "wide tread" GPWT has a 76-inch rear axle and a tricycle front. The GP-P was a modified GPWT with a 68-inch rear axle, for use in potato fields. The GPO was lowered and had fenders for orchard work. Twenty-four GPO tractors were converted into crawlers by Lindeman.
