A self-propelled forage harvester is equipped with a crop gathering device which transports crop material from the ground to feed rolls that position the crop for being chopped into small pieces by a chopper drum. To prevent pieces of crop material from accumulating on top of the housing structure for the feed rolls and the chopper drum, a flexible shield is mounted between the bottom of the operator's cab and the top of the crop gathering device. Various different access elements of the shield may be quickly opened to provide access to the feed rolls, chopper drum and other functioning elements provided for processing the crop.

1. In combination with a self-propelled harvester including a main frame supported on front and rear pairs of wheels and having a cab located on the frame in an elevated location between the front pair of wheels, a crop gathering device mounted at the front of said frame for delivering crop material
1. In combination with a self-propelled harvester including a main frame supported on front and rear pairs of wheels and having a cab located on the frame in an elevated location between the front pair of wheels, a crop gathering device mounted at the front of said frame for delivering crop material to a crop processing arrangement including functional elements mounted to said frame below said cab, a shield for preventing airborne crop particles thrown up by said crop gathering device from landing on and accumulating on housing surfaces covering said crop processing elements, comprising: said shield extending transversely across a zone extending between said cab and an upper rear location of said crop gathering device; and said shield being provided with at least one access element, movable between open and closed positions, at such a location that, when said access element is in its open position, it is possible to gain access to said functional elements without having to remove said shield. 2. The combination, as defined in claim 1, wherein said shield is constructed of a flexible material. 3. The combination, as defined in claim 2, wherein said access element is in the form of a flap. 4. The combination, as defined in claim 3, wherein said flap is held closed by a zipper. 5. The combination, as defined in claim 3, and wherein a top edge of said shield is supported from said cab by a wind-up device; said shield having a bottom edge extending parallel to said top edge; and a releasable fastener arrangement coupling said lower edge to said crop gathering device. 6. The combination, as defined in claim 1, wherein said shield is generally upright, whereby crop particles will tend to slide off the shield. 7. The combination, as defined in claim 1, wherein upper and lower edges of said shield are respectively releasably attached to said cab and to said crop gathering device by upper and lower sets of quick-release fastener arrangements. 8. The combination, as defined in claim 7, wherein said upper and lower sets of quick-release fastener arrangements each include a plurality of slot-shaped openings in said shield and a plurality of pivotable T-shaped latches fixed to said cab and to said crop gathering device and inserted through a respective slot-shaped opening in said shield. 9. The combination, as defined in claim 1, wherein said shield is made of a sound-absorbing material. 10. The combination, as defined in claim 1, wherein said shield is made of a flexible material; and said access element including a zipper located between upper and lower ends of said shield and extending its entire width, whereby when the zipper is un-zipped, the shield is divided into two parts which may be separated to provide access.
