Apparatus, systems and methods are provided for monitoring yield while harvesting grain. Grain released from paddles on the clean grain elevator chain of a harvester contacts a flow sensor which reports the rate of grain flow through the clean grain elevator. In some embodiments a brush is mounted to the chain and disposed to clean the flow sensor surface. In other embodiments a bucket mounted to the clean grain elevator chain releases grain against the flow sensor at a rate dependent on a grain property.

A cleaning assembly for a harvester operable to clean a crop while moving along a direction of the crop flow and comprising multiple cleaning sub-assemblies has a control system coupled to each of the cleaning sub-assemblies and operable to control the operation of each of the cleaning sub-assemblies in function of separate cleaning sub-assembly control settings for each of the cleaning sub-assemblies.
