1. A conditioning roller assembly for a forage harvester, the conditioning roller assembly comprising:
a first conditioning roller which is rotatably mounted on a first holder by a first bearing arrangement;
a second conditioning roller which is rotatably mounted on a second holder by a second bearing arrangement;
a pivoting arrangement which comprises a first component and a second component which are connected together by a hinge with an axis extending parallel to the longitudinal axes of the conditioning rollers, and a resilient arrangement for providing pre-tensioning of the conditioning rollers;
wherein the first holder is fastened to the first component and the second holder is fastened to the second component;
wherein the first component and second component, with the holders and conditioning rollers respectively attached thereto, can move apart during operation about the axis of rotation formed by the hinge, counter to the force of the resilient arrangement, depending on a throughput of harvested material passing through the gap between the conditioning rollers; and
wherein the first holder and/or the second holder are mounted so as to be pivotable in each case about a respective pivot axis relative to the associated first component and second component, without moving the first component or the second component relative to each other, for servicing purposes.
