If you buy a ZTR you would have more time. When I made the switch a few years ago, I saved at least a 1/3 of my time. I went from a 30hr\week moweing to a 20hr\week moweing back then. I soon filled them saved hours plus some. My mower has payed for itself and some. By the way I payed cash. I will say that If you have alot of fensed in lawns then it won't save you much time.
