A transmission assembly for a self-propelled machine comprising a transmission housing fitted with an input shaft, an output shaft, a mechanism for reversing the rotational drive direction of the output shaft, and a brake mechanism (7), each mechanism comprising a control (6, 8), said direction reversing and brake controls (6, 8) carried by said housing being mounted respectively movable, one (6) between at least three positions, i.e. a neutral position, a forward position and a reverse position, the other (8) between at least a so-called first braking position and a non-braking position, said brake control (8) being couplable to a brake control member that can be actuated by the operator, in order to shift said brake control (8) from the non-braking position to said first braking position. The brake control (8) has a second braking position separate from the first braking position, and the transmission assembly comprises return means capable, in the neutral position of the direction reversing control (6), of returning said brake control (8) to the second braking position, and means for driving the movement of the brake control (8) from the second braking position to the non-braking position, said means for driving the movement of the brake control being at least partially formed by the direction reversing control (6). |
