I've recently started doing lawn mowing, have a few small contracts and have a chance to put my bid on a new store that has moved to this location, which is Mid-Mich. The area to be mowed is approx. 10 acres with scattered small trees, lots of open area. Any ideas of how much a person should bid on this job, by the hour or by the acre. I have a 60" ZTR, 21" push, and will be getting a 36"-52" WB soon, haven't decided yet. It will be another person and myself doing the work. Also this is a brand new lawn, how long should the grass grow, for the first time before cutting? Thanks for all your help.
