Legacy of engineering design
As a democratic republic, it continued to increase its industrial output between the wars with several companies entering the tractor market with machines of their own design, including Škoda. Meanwhile, in Russia, the Soviet factories were busy trying to copy the Fordson without full access to the advanced metallurgy enjoyed by the Americans. Most of the efforts failed in one way or another, but they still persisted.After the war, production continued unabated in democratic Czechoslovakia. Yet, the young country felt threatened by its neighbours. In response to this concern, it kept the arms factory at Brno, established in 1916, busy producing small arms, including one of its own design which was adopted by the British Army as the Bren gun.
Other successful products included a nine-cylinder radial aircraft diesel engine of 260hp, as well as hard wearing small car with a two stroke, two-cylinder engine offering a more modest 18hp.Shadows of war and communism
As war loomed in the late 1930s, the factory switched back to arms production which the Germans naturally requisitioned, resulting in allied destruction of much the factory in 1944.
It was about this time, the name was coined. The 'Z' of Zbrojovka Arms factory was conflated with the 'or' of tractor, to give the world 'Zetor'.
The first tractor was really quite modern in design. It had a two-cylinder diesel four-stroke driving the rear axle through a 6+2 transmission. There were independent brakes and a top speed of 32kph (20mph), a quite remarkable figure for the time.
Big seller
Altogether 159,000 Z 25s were built up until 1961 when it was finally discontinued. It had been displaced by the larger 35 Super, and then the 50 Super, which itself sold 150,000 units in its eight year lifespan.
Modular construction
It was decided that the new tractors would rely on common components as much as possible, so twin, triple and four cylinder engines were designed, based on the same internal parts as much as possible.
The iconic Zetor Crystal
It is unwise to stand still for too long in the tractor world and, even as the UR1 tractors were proving popular, the company engineers were thinking about their successors. Extra power was obviously a requirement and a new family of engines of larger bore was created. The engine block was no longer left to carry the burden of holding front and rear together thanks to a 'half frame', or reinforcing rail which shared the stress.
ZTS demands a slice of Zetor
It was in the early 1980s that events took a downward for the Brno plant. The Cold War had ended and a tank manufacturer in the town of Martin, now Slovakia, was insisting that Crystal production was moved to its factory as the military orders dried up.Having sold 44,000 crystals Brno was forced to transfer manufacture to ZTS in Slovakia, where they would be built by workforce with no experience of tractor production.
The relationship between the two was hardly cordial and build quality suffered as a result, yet Martin went on to make bigger models of their own design.
No deal with John Deere
There was also an agreement with John Deere in 1993 by which Zetor supplied UR3 and Forterra models in John Deere livery for the Latin America market. Not only was it a customer, but John Deere also assisted Zetor in modernising its whole operation, from manufacture to parts distribution. Quite what happened to this relationship remains a matter of speculation. Yet the suggestion that the American company's attempts to buy out Zetor was coldly rebuffed, is commonly accepted by many.The modern Zetor
The last few years have seen the reintroduction of the Crystal, now powered by a six-cylinder Deutz engine. At 170hp, it has over twice the power of the original, yet in a world of increasing power requirements, that may not be enough for markets such as Europe and America.
