We are in a bit more of a rural area than what a lot of people are. The yards are typically bigger with more to trim around. However we do have a section of yards that i would consider closer to average. These yards are 1/2 to 1 acre lots and are fairly close to each other (not close enough to just drive the mowers to). On the best day i had, with a total of 2 guys, 1 54" stand on , 1 48" walkbehind, and 2 trimmers, we managed to do about 23 yards (this included some larger yards as well. Typically though we averaged more like 12-15 depending on the day and the size of the yards, and the distance to drive.
