A method for removing trash from a flow of harvested crop within an agricultural harvester using a cleaning assembly downstream of a chopper assembly of the agricultural harvester relative to the flow of harvested crop, an upstream side of the cleaning assembly being positioned closer to the chopper assembly than a downstream side of the cleaning assembly, the cleaning assembly comprising a screen and a fan, the fan being positioned at least partially between the upstream and downstream sides of the cleaning assembly, the method comprising:
- controlling, with one or more computing devices, an operation of a drive device to move the screen along a travel path relative to the fan such that a first portion of the screen is movable between the upstream side and the downstream side of the cleaning assembly;
- and
- controlling, with the one or more computing devices, an operation of the fan to generate a flow of air in a blowing direction such that the flow of air passes through the upstream side of the cleaning assembly before the downstream side of the cleaning assembly.
