Cleaner engines for the A Series
One of the most popular tractors in the Valtra model line-up, the A Series is now being offered with cleaner and more environmentally friendly engines. The main features of the A Series remain the same, but the engine technology has been upgraded to comply with Tier 3 emissions standards.
"The new engines feature an air-to-air intercooler and a new air filter that is considerably smaller and more efficient than the previous model. The A Series may look the same as before, but quite a lot of changes have been made to the engine," says Ari Leppiniemi, Project Manager in charge of the new A Series.
The intercooler is located above the radiator, allowing both cooling systems to receive the maximum amount of fresh air while reducing flow resistance.
The fuel injection on A Series engines remains mechanical and the output is approximately the same. The A72 offers 74 horsepower, the A82 offers 88 horsepower, and the A92 offers 101 horsepower (ISO 14396). The numbering system for the models is new, however.
"The A72 is a three-cylinder model, the A82 has a four-cylinder engine, and the A92 has a four-cylinder engine. The A Series name remains the same. The first number after the A relates roughly to DIN horsepower, while the second number refers to the second generation," explains Leppiniemi.
An interesting new option on the A Series is the driver's armrest equipped with a joystick for operating the front loader, as on N and T Series tractors.
One of the guidelines in renewing the A Series was to control costs. The goal was to keep the A Series a cost-effective, uncomplicated and reliable basic tractor. In this way Valtra's A Series can continue to serve farmers in this period of increasingly strict exhaust emission regulations.
Valtra will be found in Hall 9 stand E22 at Agritechnica.
