Feeder housing with torque stops for agricultural vehicle

A feederhouse assembly for an agricultural vehicle, said feederhouse assembly comprising:

• a feederhouse frame including at least four interconnected walls, an open front end, an open rear end, and a hollow space circumscribed by the four interconnected walls;
• a header adapter that includes a surface that is configured to be mounted to a header of the agricultural vehicle, wherein the header adapter is moveable relative to the feederhouse frame about a horizontal pivot axis which extends substantially parallel to a longitudinal axis of the header, the header adapter having an adapter sidewall disposed adjacent a feederhouse sidewall of the four interconnected walls;
• and
• a torque stop positioned within a gap formed between the feederhouse sidewall and the adapter sidewall, the torque stop having a low-friction bearing surface that is configured for bearing directly on one of the adapter sidewall and the feederhouse sidewall upon deformation of the frame to reduce friction between the adapter sidewall and the feederhouse sidewall when the header adapter moves relative to the feederhouse frame about the horizontal pivot axis.
