There are a lot of factors in just stating prices.
Pro street-looks like your lawns are pretty big but wide. Open. You could get 2 mowers on them and be done in no time.
Others are posting small lawns that are best suited. With a push mower.
For me my average across the board is $38. A high of 100 and low of 25. Plus some of those are mow blow go while others are full service with time spent in the landscape beds.
