An agricultural vehicle comprising:

• a chassis configured for movement on a surface;
• a header configured to remove crop material from the surface;
• a feeder housing connected between the header and the chassis;
• a shaft mounted to rotate relative to the feeder housing about a center axis;
• a first rotary drive mounted to rotate with the shaft at a first axial position along the shaft;
• a second rotary drive mounted to rotate with the shaft at a second axial position along the shaft, the second axial position being spaced along the center axis from the first axial position;
• an anti-wrap cover assembly extending an entire distance from the first rotary drive to the second rotary drive and at least partially surrounding the first rotary drive, the second rotary drive, and the shaft between the first rotary drive and the second rotary drive, the anti-wrap cover assembly being rotatably mounted to at least one of the first rotary drive, the second rotary drive and the shaft;
• and
• a connector joining the feeder housing to the anti-wrap cover assembly and configured to allow the anti-wrap cover assembly to move through a predetermined limited range of motion relative to the feeder housing.
