ABSTRACT:
The end loader bucket attachment includes a bracket attachable to the side plate of an end loader bucket, and an arm pivoting from the bracket. The pivot is oriented generally vertically to allow the arm to swing in a generally horizontal plane, depending upon the tilt of the bucket. When the bucket is tilted somewhat rearwardly, the weight of the arm causes it to swing outwardly to extend generally laterally from the bucket and end loader machine. However, when the bucket is tilted somewhat forwardly, the arm automatically swings forwardly, generally parallel to the longitudinal axis of the machine. The attachment is particularly useful in picking up suspended objects to the side of the bucket and machine, and swinging those loads to a forward position generally in front of the bucket and machine. This greatly reduces the need for maneuvering the machine to pick up and reposition such loads.
