Abstract: An operational carrier for a wheel-type hay rake has an upper frame with one end for single point attachment to the draw bar of a towing vehicle. A lower frame is disposed beneath the upper frame and pivotally connected at one end to the upper frame. A first linkage is pivotally connected at one end to the upper frame and has an opposite end for attachment to the frame of the hay rake. The lower frame is provided with means for pivotally attaching an opposite end of the lower frame to the frame of the hay rake. Hydraulic means mounted on said upper frame has a piston rod connected to the lower frame for raising the lower frame to move the frame of the hay rake when said first linkage is connected to the frame of the hay rake in a substantially vertical direction from a raking position to a transport position.
