Hay-making machine

An agricultural hay-making machine for both tedding and windrowing, comprising at least two rotors, means mounting said rotors on said machine for rotation about axes displaced from the horizontal, a plurality of outwardly extending push-rods carried by each rotor, tines carried by arms and having ends connected to the arms and free ends, and means mounting said tines for adjustive movement between a tedding position in which said tines extend downwardly from said connected ends to said free ends at a first angle to the horizontal when tedding, and a windrowing position in which said connected ends are more closely adjacent the ground when windrowing than in said tedding position and said tines are disposed at a second angle to the horizontal when windrowing which is substantially less than said first angle, said tines when windrowing being inclined to the rear from the direction of rotation of the rotor, the free ends of the tines when windrowing moving, by said adjustive movement, in a smaller circle than when tedding, each of said tines rotating substantially in a single plane while tedding and substantially in a single plane while windrowing, said tine mounting means comprising cranks articulatedly connected to said arms and to said annular support and to said push-rods.
