Sigma Power - a milestone in agricultural engineering
Valtra Sigma Power has been recognized as a significant innovation in agricultural engineering.
With Sigma Power the tractor's PTO driveline is constantly monitored and, when the PTO is in heavy use, up to 30 hp more can be developed.

The Sigma Power PTO boost was first introduced with Valtra Valmet model 8750. It received a Gold Medal at the 1997 Agritechnica, and today forms the basis for boost technology used even by other manufacturers.
