Maybe he pays low wages and is busy enough not to worry about down time. he's obviously happy with what he is bringing in or he would raise prices. It doesn't sound like he is a newbie. In my area I charge top dollar but the work comes in a lot slower. A company doing 100 lawns with 2 guys charging $60/man hour will make less then a man sitting in the office while his 10 employee's go out and bring in $35 man/hr on a continuous basis. Plus he doesn't waste as much time giving high dollars bids that are tossed in the trash the minute he pulls away. You have to look at each truck as a crew. each truck isn't going to have anymore downtime then you or anyone else, but if he pays a lot less in labor and has tighter routes with more work he can make some money in volume. The fact is no one really knows what this guy is making and you can't assume anything until you have been there and tried it. I wonder how many lawn companies are charging $60 man/hr and have 5 or more crews running at full schedule?
