Complete Guide to Rubber Track Sizes for Mini Excavators
Rubber tracks are a high-wear item on mini excavators. Ordering the correct replacement requires three key dimensions and knowledge of the internal structure.
Three Essential Dimensions
- Width (mm) — Common widths: 180, 230, 250, 300, 320, 350, 400, 450 mm.
- Pitch (mm) — Distance between adjacent drive lug centres. Common: 48.5, 52.5, 56, 72, 84 mm.
- Number of links — Count all drive lugs around the entire loop.
Internal Guide System
- Offset guide — Rail positioned to one side. Most common on newer machines.
- Centre guide — Single rail down the middle. Used on certain Kubota, Yanmar and older models.
Signs of Wear
- Visible steel cord exposure through the rubber
- Cracking or chunking of tread blocks
- Worn or missing drive lugs causing skipping
- Delamination of track layers
