Do you change the mowing height for customers or do you mow all the same. I mow most at 3" inches but go to 3 1/2" for a few and down to 2 1/2" for a few. I picked up a nice account because the last lco wouldn't change height? Is it common to not change- i don't think it takes to much time- and I have a full schedule 6 days a week with a 3 man crew. Also would be interested what is the most common height.
