Search about Vario transmissions and you'll get some nice animations and explanations of it working, mostly from Fendt. Haven't found any good explanations from Yanmar yet.This is where I get lost understanding it the concept of this.
Well said, it seems like this design would be superior to straight hydrostat but if so why is Yanmar is the only manufacturer using it?
If there is anyone who has a YT347 or YT359 I would like to know what your experience has been with this transmission.
As far as why it's not used more on smaller tractors is mainly because this transmission is crazy expensive, super complex and again, crazy expensive to repair as well. Compare the cost of an Yanmar with the iMHT to one with either a shuttle transmission or the HST.
However, I suspect in the future we might see more of these style of transmission on smaller tractors.
