The Ford 7840, 8240, and 8340 tractors are part of Ford’s PowerStar 40 Series, produced in the early to mid-1990s as high-performance row-crop and utility tractors. Designed for durability and versatility, they feature powerful Ford 6-cylinder diesel engines with horsepower ratings ranging from ~90 hp on the 7840 to over 106 hp on the 8340. Built for demanding agricultural operations, these tractors combine strong drivetrains, advanced hydraulics, and operator-focused cab options to deliver reliability and productivity in the field.
The 7840 provides around 90 hp at the PTO, the 8240 increases this to ~96–106 hp, and the 8340 tops the range with ~110 hp tested PTO power. Transmission options include 12-speed synchronized, 16-speed shuttle, and premium SLE power-shift variants, giving operators flexibility to match performance with task requirements. Hydraulics are available in open-center or closed-center load-sensing configurations, with flows from ~17.4 gpm to ~20 gpm and system pressures around 2,100 psi. Rear hitch lift capacities range from ~6,200 lbs to over 8,700 lbs depending on configuration, while fuel capacities of ~57 gallons ensure extended field operation. Wheelbases of ~103–106 inches and weights from ~8,000 to 10,900 lbs provide excellent stability and traction for heavy implements.
