CVT in the Claas Mercator Merge harvester. The pulley's powerful diameter is transformed by pushing the two conical discs possibly toward or from each other.
Therefore the standard automated is somewhat compromised since the motor has to pick from only some equipment ratios. The key reason why That is less than ideal is terus ke sana because engines are best optimised to operate only in a very slim rev range. The broader rev variety the motor should perform more than, the greater compromises the designers need to make.
