Middlesex County, Ontario | I completely agree. But a powershift sitting still at 1800 rpm and a powershift pulling at max load at 1800 don't burn the same amount of fuel. That's all I'm saying.
I've run quite a few Fendts and I see the light. We usually set the cruise faster than we can actually go and just use all the horses all the time.
I think the fuel savings during cultivating or simple tasks like that are more from the computer than from the transmission. No doubt the tranny saves fuel, but I think the computer system choosing engine RPM saves more fuel than the tranny. Farmer John (and me included) do not set the gears/RPM to the ideal setting in power shift tractors. I know Deere and others have the auto button to do this, but its so rough and jerky and it just doesn't work well so noone uses it. If we had a computer in a powershift (that actually works) to pick the ideal gear and RPM for us, I think the fuel savings would not nearly be as much compared to IVT as it is now.
And really, why don't powershift tractors have this feature?
If my powershift tractor took the last 20 minutes of pulling data (and was smart enough to ignore headland turns) and just gave me a suggestion of which gear and RPM to run that would just be fantastic. As it sits now noone really shifts or changes the throttle much anyway. Just give me a screen saying "based on the last 20 minutes of data, you should just leave it in 11 at 1450 rpm." Sure would save a lot of fuel when dad (or an amigo) runs the tractor at 2000 RPM all day long instead of throttling back to 1200.

CVT and IVT the same?
