Introduction
Massey Ferguson 4840 Four-Wheel Drive Tractor
The Massey Ferguson 4840 is a high-horsepower four-wheel drive tractor produced between 1978 and 1983. It represents a significant development in large-scale agricultural machinery, designed for heavy-duty field operations requiring high torque and reliable traction.
Engine and Performance
The tractor is powered by an 8-cylinder, liquid-cooled Cummins V-903 diesel engine. With a displacement of 14.8 liters and a compression ratio of 15.5:1, the engine delivers a net power output of 265 hp (197.6 kW). The cooling system capacity is 56.8 liters, while the oil capacity is 35.5 liters, ensuring sustained thermal stability under heavy loads.
Transmission and Drivetrain
The drivetrain features an articulated power steering system and four-wheel drive configuration. Two transmission options were available: an 18-speed partial power shift transmission, which utilizes a wet disc clutch with four 14-inch plates, and a 12-speed gear transmission. The power shift variant offers three gears in two ranges with a three-speed shift-on-the-fly capability, allowing for efficient gear selection during field work.
Hydraulics and Hitch
The hydraulic system is of the open-center type, providing a total flow of 60 gpm (227.1 lpm). This is distributed between a 16 gpm lift pump, a 16 gpm transmission pump, and a 28 gpm auxiliary pump. The rear hitch is a category IV system equipped with position control and electronic lower link sensing, capable of lifting up to 11,000 lbs (4,989 kg) at 24 inches behind the hitch point.
Operator Environment and Dimensions
The machine features a standard cab equipped with heating and air-conditioning as factory equipment. Physically, the tractor has a wheelbase of 137 inches and an overall width of 108 inches. The front and rear axles are built with 4-inch diameter components to withstand the stresses of high-traction agricultural tasks.
Conclusion
The Massey Ferguson 4840 serves as a heavy-duty platform suited for large-scale farming applications. Its combination of a high-displacement Cummins engine, articulated steering, and substantial hydraulic flow makes it appropriate for intensive cultivation and heavy implement operation.
