If you can't find the rubber track size stamped into the rubber then you can take three simple rubber track measurements that will determine which replacement track you need.

1. Measure the width of the track in millimeters.
   
2. Count the number of links in the inner part of the track.
3. Measure the distance from the center of one link to the center of the next link (in millimeters). This is known as the track pitch distance.
   

This rubber track measurement is read Width x Pitch x Number of Links.
