In the autumn of 1993, Zetor’s refreshed UR I model range was renumbered in the style of the larger X540 series. The 5211/5245 models were replaced by the 3320/3340 (51 hp), the 6211/6245 by the 4320/4340 (61 hp), and the 7711/7745 by the 6320/6340 (72 hp). The successor to the 7745 Special didn’t arrive until 1995, when it was introduced as the 7320/7340 (81 hp). Turbocharging was now factory-fitted, raising torque by 14–18 %.

The most important new feature was a powershift gearbox with a reverser offered as standard on the four-wheel-drive models. Unfortunately, the reverser was unsynchronized. The 6320–7320 models also received a substantial boost in lifting capacity (3 500 kg). Except for the smallest model, the clutch diameter was 12 inches.

When the 7340 was launched in 1995, all models received the Carraro front axle.
