AIM Attachments manufactures a complete line of heavy-duty, severe-duty, and ditch cleaning excavator buckets for machines of all sizes. These buckets feature top-quality hardened steel construction highlighted by AR400 steel cutting edges and side cutters. The buckets use AR400 steel because it is tougher, harder, and more wear resistant than any other steel plate used in the attachments industry--30% stronger and 46% harder than commonly used T-1 steel. AIM HD45 Excavator Buckets offer thick horizontal wear straps, full-curve side wear straps, and D-rings as standard features. The open design allows for easy clean-out. AIM HD45 Excavator Buckets are currently available in heavy duty and severe duty configurations for 40-45,000 lb. machines. These buckets are perfect for all general excavating and site preparation tasks.
