I learned something from your tip Xerantheum and from the comments of @robertduval14
... I learned that I've been mowing incorrectly for 45 years because
I've pretty much mowed the same path/direction every time I mow the lawn, but maybe it works out because when my husband mows, he does it just the opposite of my way and he does change it up from time to time. I just won't let him know that I found out that his way is the right way.
