The 7840 (A) is powered by a water-cooled six-cylinder diesel engine of 6,582 cc, producing 100 hp, or 73.5 kW, at 2,070 rpm. At a weight of 4,240 kg, a length of 4,361 mm, a height of 2,776 mm and a width of 2,095 mm, with a wheelbase of 2,690 mm, the machine reaches a top speed of 30 km/h.
A six-cylinder engine of over 6.5 litres and 73.5 kW belongs to a different world of work than smaller three- or four-cylinder tractors: it is built for tillage with larger implements, working with heavy trailers and demanding power-take-off tasks on larger arable areas. The high weight of 4,240 kg additionally provides ground pressure and traction for heavy drawbar work. The power take-off on tractors of this class often runs at 1,000 rpm, so as to also supply power-hungry implements.
When buying a Ford 7840 (A) secondhand, the condition of the clutch and gearbox given the power transmitted, the cooling system of the large six-cylinder engine, and the injection pump and injectors of the diesel engine matter most. Also worth checking are the brakes and the tightness of the hydraulic system for mounted implements.
