Claim:
A grain tank for an agricultural harvester having an extension assembly to enable the volume of the tank to be increased, the extension assembly comprising two pairs of mutually opposed panels that are movable relative to the tank between a lowered position in which they serve as a cover for an opening in the top of the tank and a raised position in which they define the side walls of an extension volume that communicates through the opening with the interior of the tank, characterized in that a blind is secured to one of the two pairs of mutually opposed panels to cover the grain tank when the extension assembly is raised, the blind being automatically deployed from a stowed position to an extended position as the one of the two pairs of mutually opposed panels is moved to the raised position, wherein the blind is wound about a roller rotatably mounted on the one of the two pairs of mutually opposed panels, the free edge of the blind being releasably anchored to the opposite panel of the pair.
