I have to pay US$4 to have the grasses cut neatly. Herbivorous animals will do the job free of cost but it may not be neat
I pay the local gardening guy $20 for an hours work (mowing, weeding etc). I wouldn't even go and start the mower for $20 My neighbours have a cool Shetland pony that I'll eventually get around here when I get some good fences up.
$20-30 a summer to cut the grass at my house. The key is you get one of those sprayers you put the weed killer in but then you put the $20-30 worth of gasoline into it and spray it throughout your lawn. After you have done that light a match and throw it into your lawn. All your grass will be burnt but you don't have to waste the money to get your grass cut for the rest of the summer.
