A bucket for an earth moving machine comprises a generally concave structure (32) and first and second side walls (34 and 36) located adjacent respective opposite lateral ends of the concave structure (32). The concave structure (32) together with the side walls (34 and 36) define a containment space (38) for containing a volume of material such as, but not limited to, particulate material such as rocks, sand, aggregate, or any combination thereof. The concave structure (32) has an upper region (40) at least a portion of which is configured to slope rearward to each side of a vertical mid plane V with reference to a loading direction D of the bucket (30). As a result of the rearward sloping of the upper region (40) to each side of the vertical mid plane V, if the bucket (30) were loaded to the extent that material within the confinement space (38) were lodged on the upper region (40), the material is most likely to roll, slide or otherwise move toward the side walls (34 and 36) and fall out of the containment space (38). A rock guard (48) projects over the confinement space 38 from the upper region (40). The rock guard (48) has a free lateral edge (49) that slopes or tapers in a reward manner parallel to the upper lip (46) and upper edges (42). |
