ABSTRACT:
The present invention relates to the connection of a bucket to a boom arm in a manner that provides increased break out power and increased speed as the bucket travels through its operational cycle for overall increased ground removal. This is accomplished by offsetting the hinge point of the bucket relative to the standard pivot position and providing a modified linkage assembly that automatically adjusts the bucket radius as measured between the bucket and its hinge point.
