ABSTRACT:
A transmission system for a tractor comprising a double clutch for transmitting engine output to an inner shaft consitituting part of a propelling line and to a tubular outer shaft constituting part of a power takeoff line. The double clutch includes a first and second flywheels, and the second flywheel defines a boss for relatively rotatable supporting a forward end of the outer shaft therein. The transmission system further comprises a propelling line change speed mechanism including a reversing gear and a reversing shaft for supporting the reversing gear. A rotational resistance applying device is provided on the reversing shaft for applying a rotational resistance to the propelling line by frictional engagement with the reversing gear.
