Nice Guys Finish Last.
Most lawn care companies embrace the motto, "Mow, Blow, and Go!" In other words, they're not really focused on YOUR lawn, they're just thinking about the other 7 yards they have to finish by the end of the day.
In addition, the actual business-owner probably won't be the one that's cutting your grass. You'll probably have two high-school or college aged kids making $10 an hour handling your lawn. They're gonna be less concerned with doing an excellent job, because they're just trying to hurry up and finish, so they can clock out and hit the road.
Whereas, when you hire The Slower Mower, I'm going to be the only person handling your lawn. Sure, it's going to take me longer than the two-person team of distracted Millennials, but haste makes waste. Remember: Guys that finish too quickly don't generally produce satisfying results. 😏
