I set a majority of my customer's up on a pre-paid monthly basis. I know I average about 17.5 cuts per year for each customer. More often early in the summer, less later in the year. I determine when they get mowed, and if I want to take three days off in a row, I just move customers around to fit my schedule. As long as the lawn looks good, there's never a problem. Plus, my customers know EXACTLY what they are supposed to pay each week, they just send in payment by the due date and magically, there yard is maintained.
I'm a Stihl handheld guy, with Toro push mowers, no brand loyalty on bigger mowers. You couldn't pay me to own a Ford or Dodge.
My business provides quality lawn care, but more than that, we offer even higher customer service.
