i've been approached by one of my good customers to bid their church. it has a small cemetery. the church community was doing it before but it gotten to be to much dinking around(someone will provide the mower one boy will cut it and no one wants the responsibility) i was told it took them about 5 hours to cut it. i'm not really sure how long it would take. how much less time would i be able to shave off. i'd be cutting with a 54" zero turn and a 48" walk behind. i would just trim the rest, i'm pretty fast with the trimmer. about 10% of the stones are flat. there may have been some more stones added since this pic was taken based on this info how long should it take me to mow it??? i don't think they would be too fussy just as long as it cut.
