ABSTRACT:
A combine harvester is provided with an orientable tube for discharging grain from its tank and a hydraulic jack for moving the orientable discharge tube between its extended position in which it projects from the combine harvester, and its retracted position in which the orientable discharge tube is housed within the space occupied by the combine harvester. The latter is further provided with catch means which are snap-engaged by the discharge tube when it is brought into its retracted position so that the discharge tube remains locked in this retracted position, and hydraulically controlled actuator means for releasing the catch means when the hydraulic jack moves the discharge tube towards the extended position.
