An L-shaped platform having a vertical bale gripping frame and a horizontal bale support deck is mounted on a transport vehicle for rotation through 90�� from a transport position to a bale pick-up position. In the pick-up position, tines on the gripping frame engage the top of the bale and hold the bale with the support deck in contact with an adjacent side surface. The platform is rotated to return to the transport position with the bale being supported by the support deck. The support deck includes a cross conveyor for discharging the bale laterally for stock feeding.

The method of claim 3 further including the step of; separating the bale into discrete units during discharge from the conveyor to distribute the material during travel of the vehicle. 5. The method of claim 4 wherein said bale is separated during discharge by contacting the bale with a cut-off device mounted on said platform adjacent said bale conveyor. 6. The method of claim 3 further including the step of; engaging said gripping frame on the top surface of said bale. 7. The method of claim 6 further including the step of; additionally engaging said gripping frame on at least one of said end surfaces of said bale. 8. Apparatus for handling bales of bulk material, said bale having a top surface and opposite side and end surfaces adjacent thereto, said side surfaces being parallel to the longitudinal axis of the bale and said top and end surfaces comprising bale gripping surfaces; a base support structure, a bale pick-up and support platform including a bale gripping frame with bale gripping means thereon and a bale support deck extending therefrom, said platform being mounted for pivotal movement on said base structure between a bale support position with the gripping frame extending generally upright and a bale pick-up position with the gripping frame positioned to engage said gripping means with at least one said bale gripping surfaces of a bale, the support deck being positioned to engage one of said adjacent side surfaces of the bale in non surface-penetrating contact, and selectively operable platform positioning means connected to move said platform to the bale pick-up position and return the platform to the bale support position with the bale being supported on said bale support decks, whereby said bale is removable from said deck in a direction generally parallel to the longitudinal axis of the bale. 9. The apparatus of claim 8 wherein said bale gripping means includes at least one bale piercing tine structure, a tine actuator mounted on said gripping frame, said at least one bale piercing tine being mounted on said actuator for movement between a bale engaging position and a retracted position for releasing said bale for support by said support deck. 10. The apparatus of claim 9 wherein; said tine actuator includes a rotatable tine support shaft, motor means for selectively rotating said shaft to move said at least one tine structure between the bale engaging position and the retracted position. 11. The apparatus of claim 10 including; a plurality of tine structures mounted in spaced relation on said support shaft. 12. The apparatus of claim 11 wherein said tine actuator includes a plurality of tine support shafts, said tine structures being positioned on said support shafts to engage both the end surfaces and top surface of a bale to be picked up. 13. The apparatus of claim 9 including; mounting means for mounting said base support structure on a transport vehicle, a bale conveyor carried on said bale support deck and extending transversely to the direction of travel of said vehicle, selectively operable drive means for operating said conveyor to discharge the bale from said support deck in a lateral direction relative to the direction of travel of said vehicle. 14. The apparatus of claim 13 wherein said drive means comprises; incremental motor drive means for discharging said bale in increments during forward travel of said vehicle. 15. The apparatus of claim 13 wherein said bale pick-up and support platform is L-shaped, said base support structure comprising; a base frame including a horizontal section providing a pivotal connection for said L-shaped platform and a vertical mast section, said mast section and said horizontal section providing connection points for the three-point hitch system of a tractor vehicle, and said platform positioning means includes ram means acting between said horizontal frame section and said L-shaped platform for pivoting the platform between the transport position and the bale pick-up position. 16. The apparatus of claim 15 including; support wheels connected to said bale support deck, said support deck including a top side for mounting said material conveyor and a bottom side for connection to the support wheels, said support wheels being so positioned as to bear at least a portion of the weight of a bale carried on said deck in the transport position. 17.
