Ford 9N

Last Updated: July 2024

Overview

The Ford 9N, a staple of the iconic N series, was produced by the Ford Motor Company in Dearborn, Michigan, between 1939 and 1942. Tailored for utility tasks, the 9N is powered by a 2.0L gasoline engine aligned in an inline configuration. It features a liquid-cooled side-valve mechanism, four cylinders, and a 6.0:1 compression ratio, delivering 23 HP at 2,000 RPM with a torque output of 84 lb-ft at 1,500 RPM. Operating as a two-wheel-drive tractor, it is equipped with a simple 3-speed gear transmission system and measures 115 inches in length, 64 inches in width, and 52 inches in height, with a 70-inch wheelbase. This model utilizes a manual steering system and relies on mechanical shoe brakes to manage its operation and movement. The open operator station design hints at its age as modern equivalents tend to have enclosures. A feature notable for the time, the 9N includes an electric starter system and could support a lift capacity of 798 pounds via its hitch.
