Abstract
An anti-wrapping device is described for preventing crop from being wrapped about the central shaft of a reel rotatably supported on side arms of a header of a combine. The device comprises an annular cover plate for securing to the axial end of the reel to prevent the crop from becoming entangled with projections from the reel and a tubular shroud for mounting on the header support arm to surround the central shaft of the reel, the axial end of the shroud being positioned when in use in close proximity to the annular cover plate of the reel to avoid any crop being caught therebetween.
