main lawn is just about 1 acre. most of the other 4 acres is woods, but there is a field of about 1/2 acre, with grass trails leading to it that I have to mow (to keep the ticks down).
mowing the main lawn takes about an hour and a half. doing the whole thing, trimming, mowing main lawn, and mowing out back takes about 3 hours. I also have to trim parts of the out back that is thickly weeded. Goldenrod, ferns, woody ferns, blueberries, etc. I trim the parts adjacent to the field, as i have a fire pit back there.
