A large round baler includes inner and outer runs of bale-forming belts that define a space between them in which brittle crop may fall through the gaps between adjacent belts and build up between the belt runs. In order to avoid wrapping problems a crop passage is provided at opposite sides of the space through which crop may pass from the space and gravitate to a crop feeding device which picks up crop from the ground and delivers it to the bale-forming chamber delimited by the inner run of belts.
