Abstract
A pick-up device, usable by an agricultural machine, includes a rotating part including at least one support arm, to which are attached raking and picking up tools and which is configured to pivot about a rotation axis with respect to the rotating part by at least first and second bearings, the at least first and second bearings each including an outer ring rigidly fastened to the rotating part, and with respect to which outer ring the support arm can pivot about the rotation axis. The first bearing includes an inner ring configured to pivot about the rotation axis with respect to the outer ring and rigidly fastened to the support arm. A stop mechanism connects the inner ring to the outer ring, and limits displacement of the support arm with respect to the rotating part in a direction substantially parallel to the rotation axis to a small or nil value.
