<p>A device for crushing mown crop, said device comprising a pick-up roller (6), which is rotatable about an at least substantially horizontal axis of rotation, mating crushing rollers (9,10), which are rotatable about at least substantially horizontal axes of rotation, as well as a pair of wheels supporting said device, which are rotatable about an at least substantially horizontal axis. The device furthermore comprises a rotatable supporting roller (7) extending parallel to the pick-up roller,which supports said pick-up roller, whereby said pick-up roller, at least one of said crushing rollers and said supporting roller are pivotally interconnected by means of a parallelogram mechanism, in such a manner that the relative position between said supporting roller and said pick-up roller remains constant. <IMAGE></p> |
