发明名称 Self-loading hay-bale-carrying trailer
摘要 A two-wheeled trailer has a V-shaped hay-bale-holding cradle pivoted about an axis closely above and parallel to the wheel axle. In its bale-loading position, parallel arms of the cradle extend rearwardly from the trailer and close to the ground for sliding under a large cylindrical bale when the trailer is backed-up by a tractor. The then-upright part of the cradle is tiltable forwardly and downwardly into its upright-V bale-carrying position in which it is automatically latched. The trailer is hitch-connected to a tractor by a tow-bar which is longitudinally extendably attached to the trailer chassis. A cable connects the cradle to the front end of the tow bar so that an extending pull thereon (when the wheel brakes are set) causes the cradle to tilt to its latched bale-carrying position. A latch normally holds the tow bar in its slightly extended hauling position. A brake-operating lever, and another lever for controlling the cradle and the tow-bar latches, are conveniently located within easy reach of the seated driver of a farm-type tractor.
