Abstract

A bucket assembly and operating system for a conventional front end loader that increases the dump height for a given boom length. The bucket assembly includes a cradle pivotally attached to the end of a boom and a bucket rotatably supported by the cradle. Rotative movement in the cradle and bucket between rollback and dump positions is accomplished by fluid pressure operated actuators controlled by a fluid pressure control system. Sequence valves forming part of the control system are utilized to delay the application of fluid pressure to certain actuators so that sequential motion in the cradle and bucket is achieved without the necessity of additional operator controls. A bucket latching mechanism mechanically locks the bucket in its rollback position until the bucket dump sequence is initiated.
