Here is the job: municipal airport mowing. 5001X75 paved runway and 2003X200 grass/sod runway (needs to be kept mowed shorter than 5"), sits on approx. 205 acres. Actually mowing is about 175 ac. when taking out paved areas and buildings. They want it done by the hour. Here is what I have: 150 hp tractor w/JD 1508 batwing mower (15ft), Kubota ZD21 with 60" deck, Stihl weed eater, and I also use a four wheeler w/sprayer to spray small areas w/Round-Up. What would you charge? Just remember, I'm located in Indiana, not on the east coast. I'll post what I charged this last year (they thought I was little expensive after the increase) after a couple replies. Thanks for the replies ahead of time.
