Abstract
This invention relates to a haymaking machine comprising several tedding and/or windrowing rotors which are connected to a carrying frame having a central section and side sections which are connected to one another. According to the invention, each side section includes three parts each carrying a rotor, and which are connected to one another by pins oriented in the direction of advance of the machine. Each of these parts is movable by an angle of about 90.degree. around a hinge pin with a central section or an adjacent part, so that they may be folded approximately in the shape of an upside-down U.
Claims10
A haymaking machine which comprises:
- a carrying frame which includes a central section and side sections placed on opposite sides of said central section, said central and side sections being connected to one another by swivel pins oriented in a direction of advance of said machine in working operation and about which the side sections can be pivoted for transport;
- a plurality of rotors, having adjacent work members which overlap in working operation, which are connected to said carrying frame;
- means mounted on said frame for rotatably driving said rotors during working operation and which includes drive shafts housed in said sections of said frame and which are connected to one another by couplings located in proximity with said swivel pins wherein each side section of said frame comprises three frame parts, each frame part carrying at least one rotor, a hinge pin member connecting said frame parts to one another and wherein said hinge members are oriented in a direction of advance of said frame in working operation;
- and
- means for pivoting each of said frame parts by an angle of substantially 90.degree. around said hinge pins with an adjacent frame part and pivoting each side section about said central section so that said frame parts are foldable so as to be approximately in the shape of an inverted U.
