A bale wrapper (1) for wrapping a round bale (2) comprises a holder (15) for supporting a roll of plastics film material for wrapping the bale. The holder (15) comprises an upstanding support member (17) from which lower and upper carrier arms (18) and (21) extend for carrying a fixed lower first spigot (19) and a slidable upper second spigot (22). A retaining pin (32) is engageable with a groove (38) in the second spigot (22) for retaining the second spigot (22) in a cocked position for facilitating replacement of a spent roll (4) with a replacement roll. A pull cord (39) connected to the retaining pin (32) releases the retaining pin (32) for releasing the second spigot (22) from the cocked position. A spent roll (4) is removed from the holder (15) by manually urging the empty reel (20) upwardly against the second spigot (22) for urging the second spigot (22) into the cocked position where it is retained by the retaining pin (32). The spent reel is then removed. A new roll placed on the first spigot (19) is aligned with the second spigot (22), which is released. The pull cord (39) is pulled from the cocked position by the pull cord (39) for engaging the new roll (4).
