Abstract: A wide windrow raking apparatus which may be retroactively fitted to a hay baler as an after market product or which may be fitted to a hay baler by the manufacturer is disclosed. The apparatus employs an extension frame between the hay baler and its towing tractor to which commercially available wide windrow power rakes may be attached. The apparatus includes activation and control assemblies, powered by the tractor, required to operate and store the attached power rakes. The apparatus allows the user to rake and bale hay in a one pass operation. The apparatus further provides a mechanical "power take off" extension shaft between the hay baler and its tractor. The apparatus allows the power rakes to be independent of the tractor which means that the tractor may be used for other tasks immediately after disconnecting from the baler/extension frame.
