An agricultural implement, for example in the form of a rotary haymaking machine, has a rake member (10) which is pivotable into a transport position about a shaft (14). A screening member (22) protects against accidental contact with the rake member (10) in the operative position. When the rake member (10) is raised to the transport position, the screening member (22) engages a limb (36) of an abutment pipe (38) and is deflected against the bias of a torsion bar (32) into a protective position in which it projects outwardly beyond the raised rake member. The stored energy of the torsion bar (32) assists in returning the rake member (10) to the operative position. Thus the screening member (22) is automatically displaced upon movement of the rake member (10) between the operative and transport positions and serves a useful function in both positions. |
