Ford 9N Specs

• In 1939, The Ford Motor Company introduced the N-Series line of tractors. The N-Series was the result of a collaboration between Henry Ford and Irish engineer Harry Ferguson. The 9N was the first tractor to feature both a three-point hitch and a rear power take off. These designs were used to drive the three-point or towed tools, but were also designed to prevent the entire tractor from tipping if the plow hit anything.

Engine

• The Ford 9N came equipped with a 1,961-cc straight-four engine with a flathead valve train. It features an updraft-equipped plain tube carburetor and a three-brush, 6V generator. The engine is cooled with a water pump that circulates water through a tube and fin radiator. The entire cooling system was pressurized and it features a six-blade fan with a 16-inch belt. The 9N's engine is capable of producing 20.29 horsepower and generates 84 foot-pounds of torque at 1,500 rpm. The engine features a direct-drive front-mounted distributor ignition system with a coil and automatic spark advance. It's also equipped with a 6V automobile starter that has a safety switch integrated into the gearshift. The bore on this engine measures 81 mm, with a 95-mm stroke. The compression ratio on this engine is 6.0 to one.

Transmission and Steering

• The Ford 9N is equipped with a three-speed sliding gear manual transmission. This transmission offers three forward speeds and reverse. The clutch on the 9N uses a single 9-inch plate. The plate's pressure increased and decreased in tandem with the engine speed. The steering system uses a bevel pinion with twin bevel sectors, which control both of the front wheels independently.

PTO Shaft and Hydraulics

• The power take off shaft on the Ford 9N features a 1.125-inch spline, and rotated at a speed of 545 rpm when the engine ran at 1,500 rpm. The hydraulics system on the 9N used a four-cylinder pump equipped with both automatic and manual valve control. The control lever for the hydraulics system is located to the operator's right.

Dimensions

• The Ford 9N is 115 inches long, 64 inches wide and 52 inches high. The wheelbase measures 70 inches, and the tractor clears the ground at 13 inches. Both front treads measure 48 inches wide, while the rear measure 76 inches wide. The entire tractor weighs 3,375 pounds, although the shipping weight of these tractors is 2,140 pounds.
