Yield monitoring systems for round baling machines and methods that can provide weight estimations for round bales at the time of formation are described. Balers can include those that incorporate hydraulically actuated bale kicking or pushing assemblies as well as those that incorporate spring-loaded off ramps. Farm implements including baling machines and cotton module builders are encompassed. The system includes a sensor that can ascertain a physical parameter associated with ejection of a round bale from the farm implement. Physical parameters as may be ascertained can include pressures, velocities, accelerations, etc. associated with bale ejection.

An agricultural mounted implement for the cleaning of harvested material, which cleaning is mobile and operated on a vehicle, said implement having an implement frame, a fan, and a cleaning unit. The cleaning unit has a pick-up for picking the harvested material to be cleaned; a first air distributor base connected to the fan via an air conveying channel and has a first air passage; a conveyor unit via which the cleaned harvested material is ejected from the cleaning unit; and a drop sieve which is mounted on the implement frame so as to be congruently below the conveyor unit. During operation, the fan sucks in an air flow, guides it under the first air distributor base and blows it out through the first air passage counter to the force of gravity such that the harvested material picked by the pick-up is transported to the conveyor unit.
