The Heart of the S Series

The heart of the S Series is the 84 AWI-4V AGCO Sisu Power off-road engine, which is available with groundbreaking SCR (Selective Catalytic Reduction) technology. The 84 AWI-4V AGCO Sisu Power SCR engine is the most fuel efficient on the market, offering up to 16% lower fuel consumption than competitors.

The new more efficient and powerful engines, AGCO’s continuously variable transmission and Valtra’s intelligent engine management system combine to meet the needs of even the most demanding users.

Valtra’s intelligent engine management system automatically adjusts the engine’s performances to ensure optimal fuel efficiency in all conditions.

e3 Technology

The Valtra S Series engines employ e3 technology, an SCR (Selective Catalytic Reduction) process. 

SCR is extremely operator and environmentally friendly, and it has been used in trucks already for a long time.

Valtra has introduced this technology also to tractors.   SCR technology treats the downstream exhaust with the additive AdBlue, which breaks down into harmless nitrogen and water vapor.

What’s more, e3 extends the lifespan of the engine, as it allows the AGCO Sisu Power engine to run cooler and more efficiently.
