The present invention relates to an agricultural machine with a movement transmission device of the secondary. The agricultural machine provided with at least one tool driven and comprising, on the one hand, an input shaft rotatably mounted in a housing and intended to be connected by an end opening of the casing to a power take-off of a tractor, and, on the other hand, a motion transmission device with a reduction of the secondary, kinematically connected to the input shaft and which may be at least one secondary equipment. The machine, characterized in that said transmission device is disposed in the casing (4) and comprises a secondary outlet shaft (8) mounted to rotate in the case (4) and a step-down transmission mechanism (9, 9 ') kinematically connecting the input shaft (3) and the output shaft of the secondary (8), a free end of said secondary shaft (8) being directed towards or located at the level of an opening of the casing (4).
