1. A cleaning system for an agricultural harvester, comprising:
(a) at least one sieve;
(b) a cleaning blower directed at the at least one sieve and configured to supply a cleaning air flow directed at the at least one sieve;
(c) a conveyor assembly configured to supply crop material to the at least one sieve, the conveyor assembly comprising:
(i) a conveyor frame;
(ii) a shaker coupled to the conveyor frame and configured to shake the conveyor frame; and
(iii) an endless conveyor carried by the conveyor frame and comprising a conveyor loop comprising a substantially solid surface and a conveyor driver coupled to the conveyor loop, the conveyor driver being configured to selectively rotate the conveyor loop; and
(d) a controller operably coupled to the conveyor driver and configured to cause selective activation of the conveyor driver to rotate the conveyor loop,
wherein the conveyor driver is configured to rotate in a first rotation direction and a second rotation direction opposite the first rotation direction, wherein rotation of the conveyor driver in the first rotation direction causes the conveyor loop to rotate in a first conveyance direction that extends from a front end of the conveyor frame toward a rear end of the conveyor frame and rotation of the conveyor driver in the second rotation direction causes the conveyor loop to rotate in a second conveyance direction that extends from the rear end of the conveyor frame toward the front end of the conveyor frame.
