ABSTRACT Device for working crop lying on the ground. A device for working crop lying on the ground comprising a frame and two tined rake members which are rotatable about upwardly extending rotary shafts and can be driven through gear boxes connected with the frame beam, at least one of which is arranged near one end of said frame beam and is, moreover, pivotable about an at least substantially vertical pivotal shaft with respect to the frame, whilst means are provided for inverting the direction of rotation of at least one of the driven rake members in a manner such that the device can be changed over between a first working position, in which the two rake members, viewed transversely of the intended direction of movement, are located one behind the other during operation and can be driven in a manner such that, viewed in the direction of movement, the tines on the proximal sides of the rake members move to the rear, and a second working position, in which, viewed in the direction of movement, the rake members are located obliquely one behind the other and can be driven in the same direction whereby with the end of the frame beam inclined the direction of movement in normal operation, said end being remote from the gear box rigidly secured to said frame has adjustably coupled with it one end of an arm with the aid of an at least substantially vertical pivotal shaft, whereas the end of the arm remote from the pivotal shaft has pivotally coupled with it the other gear box with the aid of the first-mentioned, at least substantially vertical pivotal shaft, with which one end of a coupling rod is coupled, the other end of which coupling rod can be coupled in different positions with the frame beam for simultaneously blocking the arm and the gear box concerned against a turn about the pivotal shaft in the two working positions.
