I have 2 guys doing 65 lawns / wk. kind of spread out, but all within 10 miles and divided by area. They could probably do another 15-20 if in the right areas. There is a company here with about 1,000+ lawns, with 6- 2 man crews doing about 100-120 a week apiece. They use only Toro 21" mowers on all of them, the owner won't even think about bigger mowers, likes the lines the small ones make. I don't know how he pays those guys but he'd have to pay me a fortune to push myself that hard for him! A friend of mines wife's brother is his right hand man, i told him to ask how they pay, i'll let you'all know when i find out.
