ABSTRACT:
Apparatus to load, transport, and unload cylindrical bales of material generally comprising a frame disposed on a trailer. The end pickup mechanism generally comprises a pair of forks secured to a shaft rotatably secured to the end of the trailer and a second set of arms extending downwardly to the ground at an angle and a set of tines pivotally secured to the end of said arms to allow limited pivotal action relative to the ground. The tines are tapered to permit horizontal pickup of a bale of material which upon rotation of the shaft transmits the bale to the vertical arms which are moved to a horizontal position onto a second set of arms on a second shaft. By rotation of the second shaft the bale is moved to a third set of arms and the bale is moved sequentially along the trailer in this manner. The bales are unloaded by reversing the direction of the shafts. This process permits picking up of the bale, moving it along the trailer, transporting the bale, and unloading it by reversing it along the trailer and placing the original bottom of the bale back on the ground so that no further waste will occur in the bale.
