Abstract: A wheeled vehicle for loading and unloading bales of hay onto and from a transportation bed includes a roller assembly cooperating with a chain drive and push plate to advance each bale or stack of bales rearwardly along the truck bed, and stabilizer arms on opposite sides of the bed have lower ends which are mounted substantially within the profile of the bed for tilting movement between a substantially upright position away from engagement with the bales and a convergent position compressed against the sides of the bales when the bed is tilted to unload the bales onto the ground.

Abstract: The invention is an apparatus for safely and efficiently loading, transporting and unloading bales, such as bales of hay. The invention includes a wheeled frame upon which a cab and bed are mounted for self-propelled locomotion across fields, lots, and roads. A bale carriage includes a pair of bale grabber arms which pivot to securely grab or clamp, and release, a bale. The bale carriage is powered for movement along an immobile carriage track overarching the cab, so that the bale may be grabbed and safely and reliably lifted along the carriage track from a position in front of the cab and deposited upon the bed in back of the cab. A push pan pushes successively deposited bales from the front of the bed toward the back of the bed to allow room for later-loaded bales. The entire bed is pivotal from a horizontal position to a vertical position.
