Abstract
A device for controlling a gear ratio of a hydrostatic mechanical power-split transmission comprises an input switch () which, when rotated, produces a particular transmission characteristic and, at the same time, limits the maximum pressure. The selected position of the input switch () selects a particular maximum pressure curve from a large number of stored maximum pressure curves.
