Combination excavating bucket having a retractable tooth arm
A combination excavating bucket adapted for connection to a power driven excavating vehicle, comprising: a) bucket comprising a transverse smooth cutting bar along its front bottom edge, b) a retractable tooth bar pivotally mounted to inner opposed lateral sides of the excavating bucket, wherein the tooth bar comprises a plurality of teeth extending outwardly from the tooth bar, and a pivot means for alternately moving the tooth bar between i) a fully-extended position, wherein the tooth bar fits over the smooth cutting bar thereby permitting the bucket to function as a tooth-edged bucket; and ii) a fully-retracted position, wherein the tooth bar is retracted away from the smooth cutting bar and the smooth cutting bar is exposed thereby permitting the bucket to function as a smooth-edged bucket, wherein the pivot means comprises first and second pivot arms pivotally mounted to the bucket.
