Valtra incorporates cleaner engines in their tractors of the a-series
January 4, 2008
"The new engine mount air-to-air cooling and a new filter that is considerably smaller and more efficient than the previous models." "Series will have the same appearance as before but with many changes in the engine", said Ari Leppiniemi, Project Manager in charge of the new a-series.
The intercooler is located on the radiator, allowing both refrigeration systems to receive the maximum amount of fresh air at the time that reduces the resistance to flow. Another new option in the a-series is an armrest with joystick to work with shovel, as in the tractors of the series N and T. The a-series engines fuel injection is still mechanical and supplied power is approximately the same. The A72 offers 74 HP, the A82 has 88 HP, and the A92 101 ft·lbf (ISO 14396). The system of numbering for models is new.
"The A72 is a model of three cylinders, while the A82 and the A92 have four cylinder engines." The name of the series to continuous equal. "The first digit after the A refers roughly to the DIN power, while the second relates to the second generation," explained Leppiniemi.
A tractor of low-cost, basic, reliable and uncomplicated
One of the guidelines for the renewal of the series was the control of costs. The objective was to maintain the series as "a low-cost, basic tractor, uncomplicated and reliable". In this way, "the Valtra series can continue helping farmers still in this period with increasingly comprehensive regulations on the emission of gaseous pollutants".
