At the Ukrainian YuMZ factory, development was slow even by Eastern Bloc standards. However, in 1998, the age-old engine was tuned to produce 80 horsepower in the 8070/8270 models. Other differences compared to the parallel 60-horsepower 6 model were minimal. During power take-off at 1000 rpm, a power output independent of the driving clutch was achieved. The clutch was stronger. The steering wheel was adjustable. The factory introduced its first four-wheel drive models alongside these: the 8270 and the 8271, equipped with a gasoline engine starter. In the early 2000s, production also included the 8080/8280 equipped with an 82-horsepower Iveco engine. However, the majority of the factory's production still consisted of the 60-horsepower 6 models.
The 8040 and 8240 models came in 2003. These had an MTZ factory engine and a 12+3 speed gearbox. The 8244 model featured a Carraro front axle. The 8040.2 and 8244.2 models had a faster 9+2 speed gearbox for road speeds. In later M models, the red parts of the outer shell were replaced with more rounded plastic parts, and the controls were modernized. Four-wheel drive models had significantly larger 12.4R24 front wheels.
