An unload tube for a combine include an upright lift portion arranged to lift grain therethrough from the onboard grain storage bin and a transfer portion connected to the lift portion by an elbow portion so as to receive grain therefrom. The transfer portion is formed from several sections coupled in series with one another for relative movement between an extended position and a retracted position in which the transfer portion is reduced in length relative to the extended position. The elbow portion is also movable relative to the onboard grain storage bin in the retracted position of the transfer portion between a working position supporting the transfer portion above the upper hopper portion of onboard storage bin and a storage position in which the transfer portion and the elbow portion are lowered downwardly in height relative to the working position.
