You don't have to deal with getting fuel for it. Sure the used truck can drive to a gas station (instead of gas cans), but it is still a hassle. Large farms will have fuel tanks behind the barn so they can drive a tractor over to fill it, but most people don't go through enough fuel to make that worth it. This you just plug in when you are done and it is always ready to go.

If you use this all day it probably won't work, but most small property owners would use it for an hour or two (over the course of an entire day), and so it always has plenty of range. I don't see why they sell gas lawn mowers at WalMart (do they still?) as for home owners electric now makes more sense than dealing with gas. Sure the big lawn mowing companies use their mowers more in a day than the battery will last, but the small home owner doesn't.
