I have been asked to bid on a trailer park and apartment complex. Using Go iLawn I come up with 2.8 mowable acres and 3600 ft. of trimming around trailers, apartments, etc... I've never really timed myself to see how long it takes to trim... say 10 ft. Wondering what the average might be and if anybody has suggestions on this type of mowing. Trailer Parks are a first for me!
