The most advanced version of the Zetor Proxima series in that year was the HS, equipped with a 3-speed quick gear and a hydraulic direction reverser. The engines were 4.2-liter inline-fours fitted with mechanical injection pumps. However, a particulate filter and exhaust gas recirculation were included as standard equipment. Both Stage IIIb and IV versions were available, the latter featuring urea injection. The wheelbase was just over 10 cm longer than other Proxima models. In Finland, the standard features included an electric three-point hitch, 60 l/min hydraulics, a push-button clutch, an air-suspended seat, and an air conditioning system.

For the year 2020, the design was modernized and the heating system was enhanced.
