Abstract: An attachment for a round hay baler in the form of a roller provided with plates mounted rigidly thereon in spaced relation along the length of the roller with the roller engaging the inner surface of the belts which form a round hay bale with the plates extending between adjacent belts and along the outer edge of the outermost belts to deflect hay from the area between the belts and preventing loose hay from accumulating interiorly of the belts with the plates forming a guide for the belts to retain them in proper aligned relation to reduce wear and maintain the belts in a proper tracking relation around their guide structures during the formation of a round hay bale.

Abstract: A farm tractor apparatus having twin front mounted adjustable hay rakes supported on the front of a conventional-type farm tractor and a hay baler mounted for pulling by said same tractor. The twin hay rakes will produce double windrows for reception by the towed hay baler of the rolled bale type for simultaneously baling two rows of hay. The hay rakes have adjustment means at the rear portions thereof to vary the width and size of the windrows produced as well as front adjustment means for varying the overall sweep width and the front expanse in order to drive the apparatus over normal roads and through normal size gate structures. The hay rakes are of the floating type and have gauge and support rollers associated therewith and being part of the combination. A feature of this invention is in the provision of hydraulic power means for allowing the tractor operator to make some of the aforementioned adjustments while in the driver's seat.
