The Hitachi EX75-2 runs a 450x81x76 track: 450 mm across the tread, 81 mm between links, 76 links around. Cut for digging, trenching, backfill and tight-quarters work and shipped free to the lower 48.
What the numbers mean on a Hitachi EX75-2
450x81x76 — 450 mm tread width (about 18"), 81 mm pitch, 76 links
Width is the tread face, pitch is the distance between drive lugs, and links is the count around the loop. All three have to match — a track one link off will not tension correctly no matter how close the width is.

How these wear
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
