If you're talking about high acreage commercial cutting, it just depends on what kind of equipment you have. If you have a 48" mower and you're bidding on a 10 acre job, I can undercut your price and still make good money if I have a 61" or 72" machine, because it will take me less time to do it. I'm not sure how to answer your question, but I can tell that you that I size up a property and have an idea in my head of how long it will take me to do with the machine that i'm currently running. I know how much ground I can cover on mine, just like you will know how much ground you can cover on your's. Some guys say $1 a minute. It just depends on how much trimming there is, etc. Hope it helps.
