Abstract
An agricultural implement for tedding, swath turning, hay collecting and similar operations. It comprises four rotors which rotate almost parallel to the ground and each of which carries series of outwardly directed tines. The four rotors may be alined transverse to the direction of motion, or they may be arranged according to a forwardly opening V or they may be arranged in a transport position in which the outer rotors are positioned practically in front of the inner rotors. Seen at the front of the implement, the two outer rotors always rotate toward one another, but the two inner rotors rotate away from one another in their first position and toward one another in their second position. This is obtained by swinging the pair of inner rotors over 180.degree. about a central, common pivot. The frame comprises a rearwardly extending main frame beam, a reversible cross beam at its rear end carrying the inner pair of rotors and a pair of adjustable side arms carrying the outer rotors.
