A material-handling bucket which includes a blade with scarifying teeth on the rear of the bucket. By raising the bucket and rolling the bucket backward, the blade and teeth can be made to engage the ground to provide grading and scarifying capabilities for a conventional loader bucket. The blade and scarifying teeth, however, do not interfere with the normal loading operations of the bucket.
