At the end of 1992, at the same time as the German 6000 series was introduced, the American 7000 series was also launched. The lineup consisted of three models: the smallest, the 7600 (130 hp), was equipped with a 6.8-liter engine, while the 7700 (150 hp) and 7800 (170 hp) had 7.6-liter engines. The engines had a constant power range of 1680-2100 rpm, and the torque increase figures were as high as 34-39.6%.
The basic transmission was the same PowrQuad as in the largest 6000 series models, offering 20+12 gears (16+12 in the 30 km/h version), and the power shuttle had 4 speeds. An optional full powershift transmission was available with 19+7 speeds. The PermaClutch II clutch was equipped with five plates. The TechCenter cab, which was 40% more spacious than the previous SG cab, had a noise level of 72 dB. The instrument cluster was digital, but radar equipment for the onboard computer was optional.
The 7600 was withdrawn from the model ranges of most European countries when the 6900, with the same power, was introduced. In the USA, the largest models of the 6000 series were not sold, and the 7000 series also included the smaller 7200 and 7400 models, and the tractors were traditionally offered with rear-wheel drive versions as well.
