In the spring of 1981, the Zetor 10 series was introduced in Finland. The color scheme had changed: the wheels and roof were now white, while the frame and cab were black. The headlights had been moved up into the grille. The roof module with its heater was manufactured in Finland. The battery under the cab was now on a sliding tray. The pedals were suspended, gears IV and V of the main gearbox were synchronized (not in the 5011 model), and there were some improvements to the controls; for example, the lift rod tilt adjustment was now located in the cab and the gear lever had been moved to the floor. In the new range, the proportion of four-wheel-drive models immediately rose to two-thirds, whereas at the same time, competitors in the small size classes remained below 50 percent. The hydraulic output and lifting capacity of the Zetor were very small compared to competitors. The power take-off could operate at 5 speeds for stationary use.

In the spring of 1984, additional work lights were added, the heater was improved, and the steering wheel shaft was equipped with two flexible joints.
