A couple of weeks ago there was a post about whether to mow first or trim first. I did not reply but I read every post. I use to trim first and then mow. I thought after reading all of the post I would try it the other way around. I have noticed several time and money saving advantages to doing this. 1. I use less fuel now on my trimmer. Before it seemed like I was filling it up every other yard. Now I go three or four yards before I fill up. 2. I use less string now than before as well. I save money and time. I guess you guys converted me.
