You are also more likely to leave indentations if the ground is soft with the extra weight, and more likely to tear up the grass turning. Just depends on where you are...on the house lawn, probably no, out in the field probably yes.
Typical loose dirt won't wear the bucket much, rocky dirt will, if it's a concern get a removable cutting edge or weld a plate to the bottom like the big boys do.
This can also be done later if you don't wait till the bucket is REALLY shot! Most of us will never see our buckets wear out, most of us have jobs or other activities that interfere with having the time to get THAT much tractor fun in!
