Abstract
An agricultural harvesting machine that comprises a crop processing mechanism and an elevator assembly for conveying harvested crop material to the crop processing mechanism is provided. The elevator assembly comprises an elevator housing, an elevator mechanism mounted in the housing, at least two flexible endless members and a plurality of slats mounted transversely to the flexible members. The slats have an S-shaped cross section that provides additional strength to the slats while reducing the chance of damage to the crop conveyed by these slats.
