ABSTRACT:
A single large round bale handling apparatus includes an elongated generally upright support frame having a main portion and an upper end portion extending in an angular relationship relative to the main portion, an upper cross beam pivotally mounted to the upper end portion of the support frame and extending in transverse relation thereto, and a pair of lift arms pivotally mounted to and supported below the upper cross beam. Elongated bale impaling prongs are mounted in generally facing relation to one another to lower ends of the lift arms. The lift arms are pivotally coupled together at their upper ends. Elongated springs mounted between the lift arms and the opposite ends of the upper cross beams apply biasing forces to the lift arms to normally pivotally move the lift arms toward an outer bale releasing position. A flexible cable is guided about a location near the upper cross beam and above the pivotally coupled upper ends of the lift arms to apply a pulling force to the upper ends of the lift arms in order to pivotally move the lift arms from the outer bale releasing position to an inner bale gripping position. By releasing application of the pulling force, the lift arms will pivotally move back to the outer releasing position under the influence of the biasing force applied to the lift arms by the springs.
