Replacement rubber tracks for the New Holland E20SR mini excavator in 300x52.5x76 — 300 mm wide, 52.5 mm pitch, 76 links. Built for digging, trenching, backfill and tight-quarters work, with free freight to the lower 48.
What the numbers mean on a New Holland E20SR
- 300x52.5x76 — 300 mm tread width (about 12"), 52.5 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.

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.
