An agricultural harvesting machine, such as a baler, is provided with a pick-up assembly and a feeder mechanism for picking up crop material from a field and feeding it to the inlet of a baling chamber. A crop retainer mechanism, such as a windguard, are mounted above the feeder mechanism for engaging the upper portion of said crop material whilst it is being fed to said inlet. The retainer mechanism is movable between a lower position assumed when no crop material is present on said crop intake apparatus and an upper position when a considerable amount of crop material is present on said crop intake apparatus. The harvesting machine is also provided with a dampening mechanism for damping the motion of said crop retainer mechanism. Advantageously, the motion is damped by a pair of gas springs mounted to the transverse rod of the windguard. This arrangement precludes sudden movements of the windguard and ensures a regular flow of the picked up material to the baling chamber.
In an agricultural harvesting machine having a crop intake apparatus for picking up crop material from a field and feeding it to the inlet of a crop collecting and/or processing device and a crop retainer mechanism mounted above said intake apparatus for engaging the upper portion of said crop material whilst it is being fed to said inlet, said retainer mechanism being moveable between a lower position assumed when no crop is present on said crop intake apparatus and an upper position when a considerable amount of crop material is present on said crop intake apparatus, the improvement comprising:
