ABSTRACT:
A tractor-drawn and powered hay harvester and conditioner has a box-type frame to which a pair of wheels are rigidly attached. The frame supports a sickle bar cutter and journals both a pick-up reel and a pair of ribbed crop conditioner rolls which crimp and flatten the stems of the hay cuttings, thereby facilitating curing and drying. A novel power drive subsystem is featured which enables both control of cutter bar height above ground and automatic adjustment of the spacing between the crop conditioner rolls as a function of crop density.
