Transmission gearing, particularly for agricultural spraying apparatuses, in which the devices for the axial displacement of the ring gears (6, 7) comprise a guide shoe (11) which engages between the said ring gears (6, 7) and is connected to a journal which is accessible from outside and is supported by the housing (1) in a manner which allows it to be rotated about an axis lying in a plane extending essentially perpendicularly to the said input shaft (3). This journal is rotatable through 180 DEG about its own axis in order to effect a transition from a stable position corresponding to the first speed into a stable position corresponding to the second speed.
