Zetor Trattore in ordine cronologico

Serial production of the Z 25 tractor began in the second half of 1946, with the ceremonial handover of the first three models taking place on the Zbrojovka premises on March 15. The Z 25 models gained popularity not only on the domestic market, but also abroad. In the very first year of production, almost 3,500 units were sold and 1,000 units were exported to Poland, Denmark, Belgium and Ireland.

On 15 March 1946 the Zbrojovka Brno factory held a small celebration – on that day the first three Z 25 tractors were delivered to customers.

Five months later, the Chamber of Commerce and Trade of the Czechoslovak Republic issued a trademark for the Zetor brand. This brand, like all ingenious, was created very simply: the transcription of the pronunciation of the letter "Z", which was used in its emblem by the Brno Zbrojovka, where the first tractors were created, was combined with the last two letters of the word tractor.

The Zetor 25 model reached 8,500 units produced in 1951. And yet, neither domestic nor foreign demand was fully satisfied.

By 1961, sixteen years after the start of series production, a total of 158,570 Z 25 tractors had been produced, of which 97,000 were exported worldwide.

This was a single-cylinder prototype of the Zetor 25 tractor. The Zetor 15 had a 15 horsepower (11 kW) diesel engine, a six-speed gearbox and a maximum speed of 22 km/h.

A – Agregační.
