My lot is ~.2 acre. My moms is ~.3 acre, and my mother-in-laws is .2 acre. I wind up mowing each of them, plus part of another .3 acre lot.
After you subtract houses and garages and driveways and sheds and stuff it's probably 1/2 acre total.
I use a Honda HRX217HYA mower, Honda HHT35SUKA trimmer, Dewalt 60V blower, Harbor Freight Greenwood 15-gallon sprayer w/Roundup, Harbor Freight Haul-Master Scooter carrier on a Haul-Master Dual-Hitch Extender.
I move everything around on a Kubota RTV500.
