The Ford 5640, 6640, and 7740 tractors are part of Ford’s PowerStar 40 Series, produced in the early to mid-1990s as versatile utility and row-crop tractors. Built with durable Ford 4-cylinder diesel engines, these models provide dependable performance for heavy-duty agricultural and industrial tasks. The Ford 5640 and 6640 are powered by a 4.4L diesel delivering about 75 hp net, while the larger Ford 7740 features a 5.0L engine rated at around 95 hp net, making it ideal for more demanding operations. With their strong drivetrains, multiple transmission options, and reliable hydraulics, these tractors are designed to excel in varied field and loader applications.
The 5640 and 6640 deliver around 66 hp at the PTO, while the 7740 steps up to approximately 86 hp, ensuring effective power transfer to a wide range of implements. Transmission variants include 8-speed economy, 12-speed synchronized, and premium 16-speed electro-shift (SLE), giving operators flexibility and efficiency. Hydraulic systems range from open-center to closed-center load-sensing (SLE), with pump flows up to 21 gpm and system pressures around 2,100 psi, enabling rear hitch lift capacities from 4,200 lbs on the 5640 up to over 6,200 lbs on the 7740. Fuel tank capacities of ~25 gallons and operating weights from 7,000 to 9,200 lbs provide long working hours and robust field stability.
The comprehensive repair manual provides complete service coverage for the Ford 5640, 6640, and 7740 models. Sections include engine system, fuel system, electrical systems, clutches, transmission systems, power take-off, rear axle and brakes, hydraulic systems, steering, front axle, cab, and tractor separation. Each section offers detailed service procedures, troubleshooting guides, torque specifications, exploded component diagrams, wiring and hydraulic schematics, and lubrication charts. This manual is essential for maintaining, repairing, and restoring these tractors to factory standards.
