Abstract
The invention relates to a digging bucket for a backhoe or similar excavating machine, wherein the effective forward digging edge of the bucket may selectively comprise a transverse row of digging teeth for use in the primary phases of an excavation or a blade-type edge used for smoothing the bottom of the excavation. The backhoe bucket structure permitting this instantaneous choice by the operator comprises a conventional bucket having digging teeth secured thereto to the forward edge of the bottom but the medial portion of the bottom of the bucket is movably mounted relative to the remainder of the bucket so that the forward edge of the movable bottom portion can be dropped to a position below the digging teeth to function as a smoothing blade.
