Introduction
Ford 771 Row-Crop Tractor
The Ford 771 is a row-crop tractor manufactured between 1958 and 1962 in Highland Park, Michigan, USA. Part of the 741 series, this machine was engineered for versatility in agricultural operations during the late 1950s and early 1960s.
Engine and Performance
The tractor is powered by a 4-cylinder, 8-valve liquid-cooled diesel engine with a displacement of 144 cubic inches (2.4 liters). It produces 48 horsepower at a rated engine speed of 2200 RPM. The engine features a compression ratio of 7.5:1 and delivers 126.8 lb-ft (171.9 Nm) of torque at 1600 RPM. A firing order of 1-2-4-3 is maintained for operational stability.
Transmission and Drivetrain
The Ford 771 utilizes the Ford Select-O-Speed transmission, a full power shift system providing 10 forward and 2 reverse gears. This configuration allows for on-the-go shifting without the use of a traditional clutch, facilitating efficient gear selection during field work. The tractor is configured as a two-wheel-drive model equipped with power-assisted steering and differential mechanical expanding shoe brakes.
Hydraulics and PTO
The hydraulic system is of the open-center type with a total capacity of 2 gallons (7.6 liters). It supports a Category I rear three-point hitch with a lift capacity of 1,250 lbs (567 kg). The tractor is equipped with a live rear PTO operating at a standard 540 RPM, allowing for the independent operation of implements.

With a wheelbase of 85.3 inches (216 cm) and a total length of 132.1 inches (335 cm), the 771 has a base weight of 3,400 lbs (1,542 kg). It provides a ground clearance of 27.25 inches (69 cm). The rear tread is adjustable from 56 to 80 inches, while the front tread ranges from 8.3 to 16.3 inches, accommodating various row-crop spacing requirements.
Conclusion
The Ford 771 is a representative row-crop tractor of its era, balancing sufficient power with a specialized power-shift transmission. It is suited for standard agricultural duties, particularly where adjustable tread widths and independent PTO operation are required.
