Abstract: A hay bale turntable for angularly rotating a rectangular jumbo size hay bale 90.degree. about its longitudnal axis while lowering the bale as it is received from a baler chamber to the surface of the earth is formed by a rigid bale support frame connected with the rearward end of a hay baler frame below the exit end of the hay baler bale chamber. A bale lowering arm frame is pivotally connected with the support frame for vertical pivoting movement toward and away from the surface of the earth. The arm frame supports a bale receiving platform having a bearing centrally interposed between the platform and the arm frame for angular rotation of the platform as the arm frame lowers it toward the surface of the earth by a fluid pressure cylinder connected with the support frame and arm frame. The cylinder is actuated for pivoting the arm frame by a fluid pressure pilot valve on the platform triggered by an overlying bale.
