Abstract
Abstract A change gear transmission, especially for agricultural and construction industry vehicles, in which a unidirectionally rotating input shaft is adapted for connection with a first counter shaft at a plurality of drive ratios for driving said counter shaft in a single direction while a second counter shaft is connected to be reversibly driven by said first counter shaft at a respective drive ratio in each direction while the second counter shaft is adapted to be connected to an output shaft to drive the output shaft at a plurality of drive ratios and in a respective direction for each direction of rotation of the second counter shaft. The transmission is, furthermore, provided with two power take-off shafts adapted for driving connection to the transmission.
