Have you priced to see what the going rate is to cut 1 acre? Around here it starts low @ $75 and up. If you have checked prices and that is the going rate $16 per acre then either move or bite your tongue and get to mowin. On the other hand, If you do not plan your route you will never gain efficiency. I used to cut 18 lawns on Thursday in 2 different neighborhoods 2 mile rad. and Friday 18 lawns 6 different neighborhoods 10 mile rad. Thursday done by 2-3pm and Friday 6-7pm. I have since changed and works out better and more efficient.
