I have a question for you all! Do you do circles when you aerate or go back and forth like striping a lawn? I have done some time trials and doing circles is almost 20% faster than the striping. However I have had customers want the going back and forth. I can't see spending extra time aerating like I do with mowing, cause it doesn't look any better either way, there are still turds on the lawn.
What ever I do I must do it right!
