Claim Text:
1. A chaff pan for a mobile steerable harvester having steerable wheels, said chaff pan comprising: a main chaff pan having oscillating elements for propelling chaff towards a discharge end adjacent the harvester steerable wheels, said steerable wheels being pivotable to a turning limit adjacent the discharge end of said main chaff pan; a deflector connected across the discharge end of said main chaff pan, said deflector having articulated end sections displaceable between a first position fully deployed to guide chaff toward the discharge end of said main chaff pan and a second position where they are displaced to a position where they clear the steerable wheels; and, a linkage connected between said steerable wheels and said deflector end sections and arranged so that normal steering movements do not displace said end sections to said second position and steering movements adjacent the wheel turning limit displace said end sections toward said second position.
