1972 - 1978
Since the launch of the first series, the UR I tractors have been constantly modernized. In 1972, the 7 series was launched with the basic models 4712, 5711 and 6711 and then the two-cylinder model 2511. The tractors have a robust yet comfortable and quiet safety cab. They are generally more massive and achieve higher performance. A total of 99,000 tractors of this series will be sold.

If you look on the back rim between the nuts there is usually engraved the month and year of them been manufactured, from that your could be built the following year. for example 10/76 would be October 1976 so yours be built in 1977.
