Valmet 702S
History

Valmet 702S

Valtra’s current model series are the F, A, N, T and S. The biggest of these is the S Series. Today’s S Series represents the third generation of the model series produced by Valtra and its predecessor Valmet. The first S Series models were manufactured already 45 years ago in Suolahti, Finland, with the introduction of the Valmet 702S. The next generation of the S Series was manufactured again in Suolahti in the 2000s, and since then the S Series has been the most powerful Valtra model series. The third generation of the S Series was introduced in 2009 and is built in France as a joint project with AGCO.

In 1971, the 02 Series was introduced, and its first model was the Valmet 502. The bigger Valmet 702 was launched the following year, and in 1973 came the even bigger Valmet 1102.

The Valmet 02 Series is remembered for its much-improved driver conditions. The cab floor was made flat, as the gear levers were moved to the right side. Noise levels inside the cab were the lowest on the market. It is no wonder, then, that 02 Series tractors were popular, especially in its home market in Finland.

An important new product launch in the 02 Series was the Valmet 702S, which further strengthened the product range in 1975. The turbocharged four-cylinder engine produced 102 horsepower (SAE). There was clearly a demand for a tractor in this size category, and the S Series was warmly welcomed by the markets. Its economy and power in particular were widely praised.

The 702S can be identified by its higher engine cover to accommodate the turbocharger. Four-wheel-drive expanded the range of tasks, even if it increased the turning radius.
According to a test report by Vakola (State Agricultural Machinery Research Institute) in 1978, the Valmet 702S offered good performance with its standard equipment.

The SAE measurement standard indicates engine power without accessories and was used in the early 1970s.

DIN indicates engine power from the flywheel with accessories.

Turbocharged engines began to grow in popularity towards the end of the 1970s, also in four-cylinder tractors. Valmet was a forerunner in turbocharging, especially in its three- and four-cylinder engines. The popularity of turbos was due to their fuel efficiency during the energy crisis of the 1970s, when the price of fuel multiplied in just a few years. In retrospect, it can be said that this Valmet innovation also came at the right time.

When four-wheel-drive was introduced to all four-cylinder Valmet tractors at the end of the 1970s, the company could offer tractors for all needs. The model series were updated again in 1979, when the tractors gained a slightly brighter yellow paint job and the S Series became the Valmet 903.
