The 2020 and 2120 were replaced in 1972 by the updated 2030 and 2130. The 2030 was equipped with the same engine as the previous 2120. Therefore, in 1973, a three-cylinder 1630 was introduced below it. The most important technical improvement in the lineup was the power take-off independent of the clutch. The OPU cabin, manufactured by Sekura, was factory-installed.

In the autumn of 1975, the front design was changed to a rounder shape (lower picture). The American-origin hydrostatic four-wheel drive was an optional feature on the 2130 model. The hydraulic motors could be connected either in parallel or in series. When connected in parallel, greater traction was achieved and the front wheels attempted to rotate at the same speed. The parallel connection could only be used on the low range of the transmission, and if one front wheel slipped severely, the front-wheel drive switched to the series position. In the autumn of 1976, mechanical four-wheel drive became available for the smaller models (up to the 2030).
