National Group in Australia. Notice the decrease in crawler track tension over the three photos? I do not know how many hours on on this machine but that is significant sagging in the 2nd and 3rd photo.

On the first photo it looks like the excavator is traveling backwards which means the sprockets are in front of the movement. In that case the full chain force is tensioning the upper track. So I believe there is no real decrease in crawler track tension on the 2nd and 3rd photo.
