Abstract: The disclosure is of a haymaking machine with two or more rake heads, a chassis, and a beam, and also means which automatically and simultaneously cause a pivoting of the chassis of the rotary rake heads about a substantially horizontal spindle of a pivot when the said chassis is pivoted about a substantially vertical spindle of the said pivot to modify its orientation in relation to the direction of travel of the machine when the latter is changed from the central tedding position into the lateral windrowing position and vice versa.

Abstract: The disclosure is of a haymaking machine with a rotary rake head and a control mechanism for adjustable tool-carrier arms which are mounted for pivoting in support bearings which are wedged between two covers, one of which is situated above the control mechanism of the tool-carrier arms and is fast with the drive hub of the rotary rake head, and the other of which is situated below the said control mechanism of the tool-carrier arms.

Abstract: The disclosure is of a haymaking machine with rotary rake heads and a chassis connected by a beam to a hitch device for coupling to a tractor three-point power lift, characterized in that the said connection beam is on the one hand pivoted at its forward end to the hitch device about a substantially vertical pivot spindle and on the other hand is fixed rigidly at its rear end to the support chassis of the rotary rake heads in such manner as to retain the said support chassis during operation in a position in which it constantly forms an obtuse angle with the direction of travel of the machine.

Abstract: A haymaking machine for central tedding and lateral windrowing has a pair of rotary rake heads carrying working tools. The tools are rotatively interconnected by means of a support chassis that carries a forwardly extending frame beam. The direction of rotation of the rotary rake heads automatically reverses when the relative position between the support chassis of the rotary rake heads and the frame beam is modified, thereby to transpose the machine from the tedding position into the windrowing position and vice versa.

Abstract: A haymaking machine for carrying out lateral discharge windrowing or central tedding, comprises a pair of rotary rake heads interconnected by a chassis. A control member causes the chassis to rotate about an axis parallel to the axis of the chassis. An intermediate element is articulated to the chassis about this axis and a beam extends between the chassis and a hitch device. The beam is articulated to the intermediate element about a vertical axis and is connected to the chassis.

Abstract: The disclosure is of a haymaking machine for the tedding and/or windrowing of fodder, comprising especially a support beam extending transversely of the direction of travel of the machine and at least four rake wheels equipped with working tools which are driven in rotation so as to rotate in directions such that any two adjacent wheels rotate in opposite directions, especially with the purpose of forming two windrows in a single passage, characterized in that each of the central rake wheels is fixed to the extremity of a support arm the other extremity of which is connected to a pivot spindle situated on the transverse support beam, the said support arms being capable of being brought by pivoting about their pivot spindles into at least two positions, the one corresponding to a first working position of the machine in which the two extremities of the support arms are respectively situated on either side of the central plane of the machine, and the other corresponding to a second working position of the machi
