For more than 50 years, Zetor have been producing quality-built, top-value tractors for the agricultural industry around the world. The manufacture of Zetor Tractors started well before the 2 nd. World War in the city of Brno in the province of Moravia which was lately part of Czechoslovakia and is more recently part of the Czech Republic. The first Distributor to import Zetor Tractors into the UK and Ireland was in 1947. Zetor was just about the only full Diesel Tractor to be sold in the UK and Ireland as other diesel tractors used petrol to start their engines. Early Zetor tractors had no starter motor and no hydraulic lift some of these tractors can still be seen in tractor museums. These models were very famous for their high road speed where speeds in excess of 40 m.p.h. were spoken about. The major turning point for Zetor occurred in 1962 when the UR1 Range of tractors were launched on the world market. This range of tractor was technically equal to any competitor in the world market and by 1978/79 Zetor was challenging the leading manufacturers Ford and Massey Ferguson for top place in the Irish Tractor Market. Another major occurrence happened in 1970 when UR11 Crystal Tractors were introduced to the market. These tractors were ahead of their time in design and technology and were the favoured tractor of most contractors and owners of large farms. While the UR1 range of tractor was extensively modified and changed in order to keep up with modern tractor technology, over the years the Crystal tractor remained unchanged for almost 30 years. Gradually its popularity declined due to the advance technology of it's competitors. The reason for this decline was the transfer of the manufacturing facility for the Crystal range from its parent factory in Brno to a factory in Northern Slovakia where they had no research and development department. This move was political where employment was moved from high density employment areas to employment black spots throughout Eastern Europe. Luckly a replacement for the Crystal range of tractors finally arrived in the mid 90's which was called the Forterra. The Forterra range brought Zetor back up to the cutting edge of modern designand and technology in agricultural tractors. Replacing the Super UR1 range we now have available the Proxima Zetor Range of tractor. This range gives the tractor purchaser in the 60 - 90 horse power range a very high level of technology and performance. Every Zetor tractor was covered by a one year warranty guarantee, no gimmicks, no fine print. Every Zetor was backed by its commitment to the customers for service after the sale. Down through the years the key note of Zetor's success has been tough, reliable tractors at an affordable price offering many years of trouble free service to their users coupled with an excellent re-sale value.

Zetor Tractor Factory Company was established in 1946 in Brno, Czech Republic, and over a 50-year span has become one of the largest tractor manufacturers in Europe. In 1998 Zetor completed production and sales of the first 1 million of the firm's Range 1 tractor units. Today Zetor tractors and implements are at work in more than 100 countries around the world. The continuing success and growth of the company is based on its traditional research and development resources. Zetor designs and produces most of its tractor components, including the engines, which are among the most fuel efficient in the industry. Throughout the past 58 years, Zetor R&D pioneered various new concepts. In 1960, the organization produced one of the first hitch-hydraulic systems (Zetormatic), with full- position, draft and mixed control capability. Later it was the first tractor company to manufacture a fully integrated safety cab with insulated, rubber-mounted suspension - an idea later adopted by all other manufactures. Again on current models, (even for the smallest Zetor, at 43 hp), Zetor pioneered a flat, vibration insulated, rubber mounted platform (operator's station) - a feature not found on any competitive model in this horse power category.
