Following transfer of manufacture of the UR II Crystal series to Slovakia, the UR I became the most important part of the Zetor portfolio. Straight away in 1984 a new series was introduced, the "series 2" with the basic models 5211, 6211 and 7211. The series was provided with a new engine allowing the front power take-off shaft driven from the rear end of the crankshaft. This series was further extended with short wheelbase vehicles for vineyards and vehicles with a lowered centre of gravity for work on sloping terrain. The 7245 H tractor was equipped with a warning system monitoring exceeded slope gradient and a safety cab.
