if you have a 1/2 acre yard then a 42" zeon would be perfect for you. i used to have a 1/2 acre yard and i cut it with a pushmower and it took 2hrs. i got a 42" residential mower and it took 1hr to mow it. a zeon could probably do it in 45min since it's zero turn. i've never seen a mean green mower. there is a greenworks electric pushmower that is 22" cut they sale at lowes but like i said it would take you 2hrs to mow your yard using that.
