Abstract: A hay-making machine having a plurality of rotary rakes thereon which are rotatably driven about generally vertical axes or rotation. The hay-making machine is supported by a plurality of wheels to facilitate its movement relative to the ground. The hay-making machine is connected by a hitch mechanism to a tractor and the rotary rakes are driven by a shaft connection to the power take-off equipment on the tractor. The hay-making machine is comprised of a main frame and auxiliary frames. The main frame is pivotally secured to the hitch and the auxiliary frame is connected pivotally to the main frame to compensate for variations in ground irregularities. Telescoping shafts are utilized on the machine to facilitate a change in length between the rotary rake members and the hitch as the hay-making machine moves relative to the ground.

Abstract: Hay-raking machine having a plurality of raking means rotatable on vertical axes. The invention relates to the type of hay rake having a plurality, as four, vertically rotatable raking devices supported by ground wheels and connectible to a tractor, as by a conventional three-point attachment means. Frame structure for supporting said raking devices provides for convenient and efficient positioning by an operator without his leaving the tractor seat for adjusting the raking means through a plurality of desired operating positions as well as for moving the raking means into an appropriately compact position for transport of same. Positive drive means are provided for driving from the power output shaft of the tractor for driving said rakes, same being arranged, however, so as to not inhibit moving said rakes into a compact body for transport purposes and at the same time when said rakes are so positioned, to terminate the driving thereof.
