<p>An agricultural rotary rake implement for working crop lying on the field. The implement comprises a movable frame which carries at least one rotary element for rotation in a substantially horizontal, slightly forwardly inclined plane. Each rotary element carries a circular array of substantially radially protruding resilient tines. A tine which is restrained in its rotary movement, is upwardly guided with respect to its mounting by means of a guide surface such as an inclined cam fixed on the rotary element, or by means of an inclination of the pivot pin of the tine with respect to the tangential direction of the rotary element, or by means of an inwardly yielding mounting of the tine.</p> |
