Valtra - Powershift versus CVT

- Valtra's N and T tractors now boast new powershift and CVT transmissions, designed in-house by the Finnish company and unveiled early last year. Emily Padfield drove the flagship T202 Direct and Versu models
How can they say that fuel economy is a reason to choose CVT? It's always and everywhere less fuel efficient than a mechanical box, since CVT is a less direct approach to delivering torque. Lots of complicated moving parts and slushing around of oil in the box. This should be true for all makes of tractor out there.
I would choose Versu or powershift, or even more preferably the Hitech mechanical box for all sorts of heavy draught work, simply because of durability and fuel efficiency. Even more so if the tractor is boosted. CVT only has one edge, and that is smooth shifting/no shifting, plus accurate creeping in front lift work etc.
Im not sure of this in Valtra tractors but, normally the CVT transmissions used on tractors are very different form the widely known inefficient belt CVT used in cars and other light vehicles. Tractors normally use a mix of mechanical and hydrostatic power multi range trasmission.
Ignafiltro Sanchez You are right, but that's exactly the wasteful part of tractor CVTs, the hydrostatic half of the transmission. Fluid based systems always give way under torque in the adjustment phase. Belt variators are of course even worse.
That's why it seems to me only a half truth to claim CVTs are more fuel efficient. They are in the sense that the engine and the gear ratio can seamlessly adjust to operate in the most efficient combination, but in terms of the actual mechanics, they can not be.
To have the right speed for each application. Some tractors have 64 gears.
CTV is a Transmission system (Continuously Variable Transmission)
@sleezypick13 continously variable transmission
Why has this gray tractor got 2 mufflers?Have never seen this on a produciton before.Have seen lime green Steiger tractors with air cleaners on both of the cab.Valtra is owned by a American company called AGCO
valtra dosent have CVT they have IVT like Fendt and john deere if im not mistaken.
those who use CVT are case and styer.
what horsepower the t202?
211 hp. w. boost
CVT and IVT are the same thing, standing for Continuously Variable Transmission or Infinitely Variable Transmission, it's just a different name... Ha.
Why would someone need 30 forward gears?!
In soviet russia car drives you!
