A draft tongue for a powered implement is designed for optionally including a first or a second coupling structure adapted for connection to draft links of a towing vehicle. The first coupling structure includes a gear transmission having an input shaft for connection, by means of an articulated power shaft, to the power take-off of the towing vehicle, and being mounted for swivelling, relative to an output shaft, about a verticle axis. The second coupling structure simply includes a support for a pin that is universally connected to an elongate member having opposite ends adapted for being coupled to the draft links of the towing vehicle.
