Abstract: A hay bale trailer (10) for transporting and unloading cylindrical hay bales (B) having a plurality of cradle assemblies (16) supported on the trailer (10) with each cradle assembly (16) including a cradle (22) mounted for tilting movement about a horizontal axis (34) between opposed sides of the trailer (10) to permit selective unloading of cylindrical hay bales (B) from a desired side of the trailer (10). Each cradle assembly (16) includes a turntable (35) on which a cradle (22) is mounted for pivotal movement about a vertical axis (46). Upon unlocking of cradles (22) by removal of locking pins (54) from openings (36), the cradle can be manually pivoted for dumping. Springs (76) return cradle (22) to a hauling position. Cradle assemblies (16) as shown in FIG. 10 can be simultaneously unlocked for individual dumping. Actuating rod (100) unlocks levers (66).
