The Ford 9280, 9480, 9680, and 9880 tractors are part of the heavy-duty 80 Series articulated 4WD lineup produced in the mid-1990s. Built for maximum field productivity, these tractors feature powerful Cummins 6-cylinder diesel engines ranging from 10.0L in the 9280 to 14.0L in the flagship 9880. Engine outputs range from approximately 250 hp in the 9280 to 400 hp in the 9880, providing unmatched pulling power and efficiency for large-scale farming operations.
The 9280 is powered by a Cummins 10.0L delivering around 250 hp, while the 9480 and 9680 increase performance with larger displacements and ratings near 300 hp. The 9880 leads the series with a 14.0L Cummins engine producing about 400 hp. All models are equipped with 12-speed partially synchronized transmissions, articulated 4WD drivetrains, and heavy-duty final drives to handle the largest implements. Hydraulic systems are closed-center, load-sensing types with pump flows between 25β30 gpm and operating pressures around 2,500 psi, ensuring consistent power for remote valves and hitch operation. Rear lift capacities exceed 12,000 lbs, and independent PTO options provide 1000 rpm for large implements. Fuel tanks of 245 gallons allow for long days in the field without frequent refueling.
The comprehensive repair manual provides full factory service coverage for these models. Sections include engine, fuel system, electrical system, transmission, axles, brakes, PTO, hydraulic system, steering, frames, cab, climate control, and three-point hitch. Each section features step-by-step procedures, exploded component diagrams, lubrication charts, torque specifications, wiring and hydraulic schematics, and troubleshooting guides. This manual ensures accurate maintenance, professional-level repairs, and long-term reliability of these high-horsepower tractors.
