Abstract
Abstract Hay rake apparatus of the side delivery type. The rake apparatus may be supported in front of a tractor by adjustable support means, such as by a boom or the like, for either left hand or right hand delivery. The rake apparatus may be attached at the rear of a tractor to be drawn behind the tractor, for either left hand or right hand delivery. In any position with respect to the tractor, the rake apparatus can be used for either raking or tedding of hay. The rake apparatus may be attached behind a truck, or automobile, or the like for rapid travel over roads, highways, and the like. The rake apparatus can be easily and readily changed from one type of operation to another type of operation.
