The invention relates to a haymaking machine at least two gyroscopes which have working links such as tines or the like distributed over the circumference and rotate around approximately vertical axes, which are inclined forward towards the ground and their outer or outer Rotary hydraulically raised Tierden. The purpose of hydraulic lifting of the or the external It is roundabout, the greater width of the haymaking machine during work on a narrower transport width to reduce.

It is known that this Zv-corner by hydraulically operated Reach pull cylinder au, the disadvantage is the higher price of the pull cylinder compared to pressure cylinders and still the more complex construction and control due to the inertia of the oil and the cylinder.

The invention is based on the object of using G-round of pressure cylinders, preferably hydraulically operated and single-acting, and a lifting linkage or the outer rotors from the working position, in which the rotors adapt freely to the unevenness of the ground can swivel into a folded up transport position.

This object is achieved according to the invention in that the lifting is actuated by a pressure cylinder takes place with the interposition of a lifting rod with an intermediate link, which allows free mobility in any working position. The advantages that can be achieved with the invention consist in the inexpensive and simple design, in particular the use of printing cylinders, preferably seeming laughable. The simple design of the lifting linkage with an intermediate link is also advantageous welekes a free movability it of the outer top in Working position and its quick adaptation to uneven ground it is guaranteed

while in the transport position the outer rotors are below Using known locking elements are firmly locked and against unintentional folding down to be secured "

An exemplary embodiment of the invention is shown in the drawing and is described in more detail below. In the drawing, the rear view in the direction of travel of an exemplary embodiment is shown. The outer gyroscopes are attached to the support frame 9 in an articulated manner and pivoted approximately in a vertical direction. By actuating the pressure cylinder 1, the lifting rod 2 is pivoted about the pivot points 10. As a result, the outer gyroscopes 4 are pivoted by the intermediate links 3 out of the working position 6, 6 ', 6''into the transport position 8, in which the gyro support frame 7 is locked . The stopper is dimensioned so that the center of the outer rotor in the transport position outside the perpendicular to the outside is located out so that the outer rotors may automatically fold back out of the transport position to the working position as soon as the lock is released "The intermediate member 3 can aua a rope , a chain or steel struts with an elongated hole, οζ'ά. exist,,
