The gearcase for transmitting motion with different speeds to at least two driving shafts in self-propelled farm machines forms two contiguous chambers and has a driving shaft. A main driving shaft enters a first chamber, and has a head which extends into a second chamber for transmission meshing with a driven shaft. Another driven shaft is provided with a set of speed-shifting gears, is arranged below and parallel to the main driving shaft and transmits motion to a third driven shaft accommodated in a housing lying below the first chamber. |
