Abstract: A rock trap for a combine is described wherein the rock trap is positioned below the upper rearward end of the combine feeder housing. The rock trap comprises a panel which is pivotally connected at its rearward end to the combine and embraces the underside of the rearward end of the feeder housing. The panel has an opening formed therein which communicates with a rock trap box which extends downwardly from the panel. The lower end of the rock trap box is selectively closed by a pivotal cover which may be manually opened to dump rocks which have accumulated therein.
