ABSTRACT:
The bale handling farm trailer comprises an elongated chassis, a front bed frame overlying and coextensive with the chassis and having a flooring secured to and extending across the front section of the front bed frame. The rear end of the latter is pivoted to the rear end of the chassis for pivoting movement to an upwardly tilted bale unloading position. This front bed frame defines a cavity rearwardly of the front bed flooring. A rear bed fits within the cavity and is pivoted to the rear of the front bed frame for movement between a rest position fitting within the cavity and resting on the front bed frame with both bed floorings in alignment and forming a continuous surface to an upright bale unloading position relative to the front bed frame. Hydraulic cylinder and piston units pivot the rear bed with respect to the front bed and the front bed with respect to the chassis. A bale pusher assembly serves to successively move the loaded bales from the back to the rear of the two bed frames. The trailer is equipped with a bale loader which picks up the bales while the trailer is on the run and loads them onto the front bed frame. The loader also serves to rotate the bales so as to bring their axes parallel to the long axis of the trailer. The bales on the rear bed frame can be unloaded as a stack. Alternately, all bales on the two bed frames can be discharged as a horizontal pack.
