CVT in the Claas Mercator Merge harvester. The pulley's successful diameter is altered by pushing the two conical discs possibly toward or faraway from each other.
They can be junk, and value a great deal to rebuild after they do go out, a single transmission expert instructed me that they gained’t even idiot with them! Much too lousy, I was seeking the KIA Sorento, but after staying told this, am remaining away!
