I just got asked to mow a local church in the area the problem is i have never estimated anything on this scale before it is about 5+ acres which isn't a problem if it was flat mowing but it has a drainage ditch that runs about 200 yards down the center of it and a dike/drainage ditch that is on 2 side of it and both of them run about 150 yards long. They will not be able to be hit with the ztr it will have to be push mowed or hit with the trimmers. now the other catch is that this was new construction last year and was just graded off and seeded needless to say it is a little rough. will this compact down throughout the year? I am sorry guys I am new commercial lots I am mostly residential right now. I am just asking for tips on estimating it and on how to take care of the long dike like embankment. Thanks in advance for all the help!
