ABSTRACT:
A round baler is provided with a bale wrapping mechanism including a wrap material guide assembly comprising a guide pan having an operative position wherein a guide surface is disposed upwardly for guiding wrap material into the baling chamber by way of a gap existing between adjacent fixed rolls forming at least a portion of the baling chamber. The guide pan is mounted for pivoting vertically and shifting fore-and-aft for permitting it to move to a inoperative position wherein a majority of the guide surface is disposed near vertical with the remainder being steeply disposed so that crop material and dirt will not accumulate on the guide surface. A wrap material cutting device includes a knife assembly including a knife mounted between opposite arms and being pivotal between a stand-by position, wherein the knife is disposed below a feed path of the wrap material when the latter is passing through the gap into the bale chamber during wrapping of a bale, and a cutting position wherein it traverses the feed path. At least one coil extension spring is coupled between the knife assembly and the guide pan for causing the latter to be moved to its inoperative position whenever the knife is moved to its operative position and to be moved to its operative position whenever the knife is moved to its stand-by position.
