Introduction
Ford NAA Utility Tractor
The Ford NAA, also known as the 'Golden Jubilee', is a utility tractor manufactured between 1953 and 1954 in Highland Park, Michigan. Released to commemorate Ford's 50th anniversary, this model represents a significant transition in the brand's agricultural equipment history, succeeding the 8N series.
Engine and Performance
The tractor is powered by a 134 cubic-inch (2.2 L) liquid-cooled, 4-cylinder engine with an 8-valve configuration. It produces approximately 33 horsepower. The engine operates at a rated speed of 2000 RPM, with a recommended operating range between 1500 and 2000 RPM. It features a compression ratio of 6.6:1 and delivers 110 lb-ft of torque at 1400 RPM.
Transmission and Drivetrain
The Ford NAA utilizes a gear-type transmission providing four forward gears and one reverse gear. Power is transmitted through a dry disc clutch. Gear shifting requires the tractor to be fully stopped and the clutch to be engaged. The machine is configured as a two-wheel-drive unit with manual steering and differential mechanical drum brakes.
Hydraulics and Hitch
The hydraulic system is of the 'live' type, providing a pump flow of 4.8 gpm (18.2 lpm) at a pressure of 2000 psi (137.9 bar). It features both position and draft control for the Category I rear hitch, which offers a lift capacity of 800 lbs (362 kg). The rear PTO operates at 540 RPM at an engine speed of 1500 RPM.
Dimensions and Specifications
The tractor has a wheelbase of 73.875 inches (187 cm) and an overall length of 118.875 inches (301 cm). It maintains a ground clearance of 13 inches at the frame, with 21 inches of clearance under both the front and rear axles. The front and rear treads are adjustable between 48 and 76 inches to accommodate various row crop requirements.
Conclusion
The Ford NAA is a classic utility tractor designed for general farm work and light agricultural tasks. Its combination of a 33-horsepower engine, live hydraulics, and a Category I hitch makes it a versatile machine for small-scale operations and a notable piece of mid-century agricultural engineering for collectors.
