Built from high-strength structural steel, it combines a compact 2.75 cu ft capacity with four CAT-style replaceable teeth for digging performance in a heavy-duty format. AR400 reinforcement is applied to critical wear areas, including the bottom wear straps, side wear plates, and side cutters, helping protect high-contact sections during demanding work. A standard C-type lifting hook is also included for practical handling when the bucket is not mounted to the excavator.\u003c\/p\u003e\n\n\u003ch2\u003eHeavy-Duty Excavation Performance\u003c\/h2\u003e\n\u003cp\u003eThe 18-inch working width is suited to trenching and general excavation where a narrower digging profile is required. Four CAT-style replaceable teeth provide the bucket’s digging edge, while the replaceable-tooth design supports serviceability when tooth components require replacement. The 2.75 cu ft capacity offers useful material-handling volume while retaining the focused working width associated with trenching applications.\u003c\/p\u003e\n\n\u003cp\u003eFor increased protection in high-wear zones, the bucket uses AR400 reinforcement on the bottom wear straps, side wear plates, and side cutters.
