Introduction
Ford 841 Utility Tractor
The Ford 841 is a utility tractor produced between 1957 and 1961 at the Ford manufacturing facility in Highland Park, Michigan. As part of the 800 series, this two-wheel drive model was designed to serve as a versatile workhorse for general agricultural operations.
Engine and Performance
The tractor is powered by a liquid-cooled, 4-cylinder, 8-valve engine with a displacement of 172 cubic inches (2.8 liters). It produces 56.3 horsepower at a rated speed of 2200 RPM. The engine delivers a peak torque of 140.4 lb-ft (190.4 Nm) at 1400 RPM, providing the necessary pulling power for field tasks. It utilizes an oil bath air cleaner and maintains a compression ratio of 16.8:1.
Transmission and Drivetrain
The standard configuration features a 4-speed unsynchronized gear transmission providing four forward and one reverse gear. An optional Sherman Step-Up/Step-Down auxiliary gearbox was available, which expands the range to 12 forward and 3 reverse gears by providing over-drive, under-drive, and direct-drive ratios. Models equipped with this auxiliary gearbox were designated as 841S.
Hydraulics and Hitch
The hydraulic system is an open-center type, operating at a pressure of 2000 psi (137.9 bar) with a total flow capacity of 4 gallons per minute (15.1 liters per minute). The tractor is equipped with a Category I rear hitch, capable of lifting 1,250 lbs (567 kg), allowing for the use of various standard implements.
Mechanical and Dimensions
Built on a 74.5-inch (189 cm) wheelbase, the Ford 841 features manual steering with optional power assist. Braking is handled by differential mechanical expanding shoe brakes. The tractor is configured with 6.00-16 front tires and 12-28 rear tires, with adjustable front and rear tread widths to accommodate different row spacings.
Conclusion
The Ford 841 is a robust and mechanically straightforward utility tractor. Its combination of a reliable 172-cubic-inch engine, optional multi-speed auxiliary transmission, and standard Category I hitch makes it well-suited for general farm tasks and maintenance work.
