In 1971, the 770, 880, and 990 Selectamatic models introduced in 1965 were replaced with improved versions 775, 885, and 990. Above these came the more powerful 995 and 996. The main differences in the 996 compared to the 995 were a dual clutch and a manually operated independent power take-off. The frame was extended by 8 cm due to the consecutively positioned clutches. Hydrostatic steering was also introduced to the 995 with the launch of the 996. The 775 model was sold mainly in Germany. The 885 was shorter than its predecessor, the 880, and was based on the core technology of the earlier 780.
Selectamatic hydraulics with push-rod sensing were already familiar from earlier models. The transmission was now partially synchronized (Synchromesh). A drawback of the transmission was the large gap between the two highest gears. On the other hand, there were plenty of low gears. All models had a 2-speed power take-off. Like DB models, except for the 996, the clutch was a dual clutch, which required the tractor to be stopped when engaging or disengaging the implement. In the 885, the clutch disc diameters were 254/254 mm, in the 990-995 models 279/254 mm, and in the 996 the dual clutch was 279/279 mm. Four-wheel-drive models equipped with Italian Selene axles were not imported to Finland. The cabin was either a Swedish Klippan or a Taavi manufactured by the Ylö factory in Finland. The heater was an optional extra. An alternating current generator was introduced in 1973.
