Valtra was granted European and US patents for the hydraulic assistant function.
The unique feature, which is part of the stepless and powershift transmissions of N and T Series tractors, improves the tractors efficiency. Conventional automatic transmissions will change to a bigger gear whenever possible, resulting in the reduction of engine revs. This maintains good fuel efficiency, but in some tasks may result in poorer output of the work hydraulics.
Valtra’s hydraulic assistant ensures that the hydraulic output is always at the required level. This is achieved by the transmission changing to a lower gear when possible while at the same time raising the engine revs in order to maintain driving speed.
Valtra's hydraulic assistant feature is especially useful in front-loading work and when operating hydraulic trailers.
