Belarus introduced models meeting different emission requirements as regulations tightened, and all the old versions remained in the lineup for markets that were satisfied with them. The novelty of the 4-series was the common rail injection system, which allowed meeting Stage IIIA requirements. The 5-series introduced in 2013 featured urea injection, achieving Stage IIIb/Tier 4i levels. In 2015, the 6-series came out, equipped with an oxidation catalyst and emissions compliant with Stage IV/Tier 4. It is noteworthy that these requirements were met with their own engines, although at the lower emission levels, engines purchased externally were initially needed.

The 150-210 horsepower Belarus tractors did not gain much popularity, at least in Europe. Their technology was quite simple for their size class. The transmission was 16+8 or 24+12 without creep gears. The lifting capacity was 6.5 tons, and the power lift was standard.

In autumn 2019, the 1523.6 was introduced with a new appearance.
