The Bobcat E63 runs a 400x72.5x76 track: 400 mm across the tread, 72.5 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 Bobcat E63
- 400x72.5x76 — 400 mm tread width (about 16"), 72.5 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.

Same track, other machines
Track size follows undercarriage geometry, not brand, so 400x72.5x76 shows up on machines from several makers. If you run any of these alongside the Bobcat E63, it is the same belt:
