Our HOA requires weekly (during growing season) lawn mowings. So on top of the $450/mo, we also have to fork over $30-50/wk to some maintenance company. They take around 10 minutes to do the entire lawn, mow, edge, weed, and pickup. I cannot complain about the speed, or the cost actually.
My neighbor has a family member come and do their lawn (I offered my guys to them for free, and they turned it down). So every Wednesday or Thursday, for nearly 4 hours, there are various 2-stroke engines going on. It is a HUGE noise, and my home office faces their house so for most of the day I'm having to ask people to repeat themselves because I cannot hear them over the sound of the neighbor's lawn equipment.
