Again, the answers to your questions will depend on your property and your equipment needs. We have 20 acres here and I mow about five with a JD 455 60" deck. My tractor is a little large to be mowing, but because I had the JD I didn't need that in a tractor. If there is enough need to justify a tractor around the place other than mowing the yard I would keep the zero turn and base my tractor purchase on the other requirements. IMHO a dedicated mower that's designed for that job would be a better solution than trying to adapt the tractor to the job.
