Connection arrangement for an agricultural harvester

A connection arrangement between a feed roller and a gear box of a forage harvester comprising:

• a gearbox shaft with a central through bore rotatingly supported in a gearbox housing around an axis of rotation, an outer surface of a distal end of the gearbox shaft being provided with ridges;
• a feed roller shaft rotatingly supported around the axis of rotation, the feed roller shaft having a central blind bore aligned with the central through bore of the gearbox shaft, an outer surface of a distal end of the feed roller shaft being provided with ridges;
• a connecting shaft located within the central bores of the gearbox shaft and the feed roller shaft;
• a sleeve having internal splines, the sleeve surrounding the distal ends of the gearbox shaft and the feed roller shaft wherein the splines match the ridges of the gearbox shaft and the feed roller shaft so as to provide torque transmission between the gearbox shaft and the feed roller shaft;
• and
• a locking element securing the splined sleeve axially in position about the distal ends of the gearbox shaft and the feed roller shaft.
