<p>A round baler includes a base frame 10 and rear movable frame 14. A first set of rollers 40a-40j is mounted in the rear frame 14 and extends transversely thereof. A pair of arms 46 is pivoted on the base frame 10, and a second set of rollers 50a- 50f is carried by the arms 46 extending transversely therebetween. The arms 46 are movable between a bale starting position and a full bale position, and the secend set of rollers 50a-50f cooperates with at least part of the first set of rollers 40a-40f to define a bale starting chamber 84 that is horizontally elongated when the arms 46 are in the bale starting position. In an alternative arrangement the first set of rollers 88a-88f, 90a-90c is mounted, at least in part, on the base frame 10 and extends transversely thereof. Some rollers 90a-90c of the first set of rollers 88a-88f, 90a-90c equally may be mounted on the rear movable frame 14. The pair of arms 92 is pivoted on the rear frame 14 and the second set of rollers 96a-96f is carried by the arms 92. In this arrangement, the second set of rollers 96a-96f cooperates with at least part of the first set of rollers 88a-88f, 90a-90c to define a bale starting chamber 102 that is vertically elongated when the arms 92 are in the bale starting position.</p> |
