Rock handling attachments

A rock handling bucket for a vehicle, comprising:

• a) a generally planar back wall extending laterally at a rear of the bucket between opposed sidewalls, the sidewalls projecting longitudinally forward from the back wall to laterally bound a rock collection space of the bucket, the rock collection space open to a front of the bucket and bounded at the rear by the back wall, the back wall formed from a plurality of rear crossbars extending laterally between the sidewalls and spaced vertically apart from each other by respective back wall openings providing visibility through the back wall, and the back wall defining a back wall plane in which at least some of the plurality of rear crossbars lie;
• and
• b) a base extending laterally between the sidewalls and longitudinally from the back wall to a cutting edge at the front of the bucket for bounding the rock collection space from below, the base formed from a plurality of base crossbars extending laterally between the sidewalls and spaced apart from each other longitudinally by respective base openings sized to facilitate retention of rocks larger than the base openings in the rock collection space and sifting of finer ground material from the rock collection space, at least a rear portion of the base defining a base plane in which at least three of the base crossbars lie, and the back wall projecting upwardly and forwardly at an incline relative to the rear portion of the base with the back wall plane intersecting the base plane at an acute angle open to the rock collection space.
