System Notes — IMPLEMENTS
The implements group covers the working attachment and its linkage: bucket or blade, cutting edges, teeth and adapters, pins and bushings, linkage arms, tilt cylinders and the wear plates that protect them. This is the group that actually does the work, so it wears fastest. Cutting edges round off, teeth break at the adapter, and pins and bushings develop play that spreads shock loads back into the linkage. Parts here are replaced on measured wear — pin and bushing clearance, edge thickness, tooth height — rather than on hours, because a worn edge costs fuel and cycle time long before it fails outright.
