At the Ukrainian YuMZ factory, the MTZ-5 tractor was manufactured until 1972, although production at the Belarus factory had ended almost 10 years earlier. Even after this, the factory did not make significant advances in tractor technology. The YuMZ-6, introduced in 1971, featured a 4.9-liter engine from the Rybinsk plant, more powerful hydraulics than before, and larger tires. The transmission still had 10+2 gears, and the gear layout in the shift pattern was quite distinctive. Initially, the cab resembled the Belarus model from the 1960s. In export brochures, the model appeared under the names Belarus 6M and 6L (electric or gasoline start). A new cab and an angular engine hood design reminiscent of Belarus were introduced in the late 1970s. The 6KM model, introduced in 1985, had a cab similar to that of contemporary Belarus tractors. By this time, the factory had produced 1.5 million tractors.

The YuMZ-6 was sold in export markets under the Belarus name, but for example, in Sweden, the model was initially known as UMZ-60. In 1985, the export model 611 was launched, which was also sold in Sweden as Belarus 611. The updated export model YuMZ-650 and the first four-wheel-drive model YuMZ-652 with MTZ's front axle were introduced in 1991. It was also sold in the USA, which was YuMZ's most important Western export market.

YuMZ's technical specifications remained fairly consistent from the 1980s into the 2000s. At some point, the steering was changed to hydrostatic. In the transmission, which changed from 10 gears to 9 gears, the 5th gear was the same in both ranges. YuMZ also produced many tractor excavators based on the 6 series.
