I have an Xmark Laser Z 48" with bagger. I bought it used and need to find out how to figure what it cost to operate, so I can Figure my cost to help set my pricing. Does that make sence. I've read hundreds of posts today and have seen and like the $1 min charge, How ever I believe that is to much for this area. Small town/Rural. I've not a clue what to charge, I've got a couple of yards I know I am under charging, and a few I think I am pretty decent with. ( I am happy with the price and the cutsomer sems to be also) Any thoughts??
