    • The invention relates to a hydrostatic transmission device (1) comprising a pump (12), a first motor (14), a second motor (16) having two basic motors (161, 162), each of which, along with the first motor, have a first and second supply/exhaust chamber. In an operating mode and in a road mode: the second chamber (161B) of the first basic motor (161) of the second motor and the first chamber (14A) of the first motor (14) are connected in series, the second chamber (14B) of the first motor being connecting to the second port (12B) of the pump; and the second chamber of the second basic motor (162) of the second motor is connected to the second port of the pump. In the operating mode, the first chamber (161A, 162A) of the two basic motors of the second motor is connected to the first port (12A) of the pump. In the road mode, an isolation means: isolates the first chambers (161A, 162A) of the first and second basic motors of the second motor from one another; connects one (161A) of the latter to the first port of the pump; and connects the other (162A) to the second port (12B).
