A bale support arm is raised into the space between a bale trailer frame and the bale lift fork thereof to prevent a large round bale from sagging into that space, and possibly being damaged, during loading of the bale. Pairs of parallel frame links connected to the frame of the trailer and links connected to the fork are pivotally connected respectively to define hinge joints. In one embodiment of the invention for low-bed bale trailers, the bale support arm extends between the hinge joints. As the fork pivots upwardly, the arm is lifted as the links fold upwardly into the space between the fork and trailer and partially supports the tilting bale. In a second embodiment for high-bed bale trailers, a pair of arm lifting levers are connected to the hinge joints. The levers are connected by respective anchor links to the fork, and the bale support arm extends between the outer ends of the levers. As the hinge joints are raised, the levers are pivoted about their connections to the anchor links, and the bale support arm thereon is pivoted into the space between the fork and trailer to support the tilting bale.
