When ordering replacement rubber tracks for mini diggers or excavators there are several ways to find out which size you need. First, check your existing rubber tracks to see if the size is stamped into your mini digger rubber tracks. It is usually very difficult to find the excavator track size as it is common for the stamp to wear off during normal use. If you can't find a rubber track size stamped into the rubber track then you can take three simple measurements that will determine which replacement track you need.
