First, after mowing? Around the edges first, or hit all the tree's and lawn ornaments then finish on the edges? I like to hit the edges first, then finish on the tree's and things in the middle of the lawn. I guess if you want to get picky, I walk in a counter clock-wise motion. I also fill the tank up, and take an extra length of line with, just in case. My biggest pet pev is the guy on the trimmer is always working in the same area I'm trying to mow. Can't they see the big yellow mower? I heard this was a good question to ask.
