I mow my 2.5 acres with a Cub Cadet 60" zero turn from Tractor Supply. They usually go on sale a couple times a year for $3599 (reg price $3999). Has 3 year warranty and upgraded transmission axles that you can service, which is a feature typically found on entry level models from the high end mowers (Scag, Bad Boy, etc). I made the mistake of purchasing a 48" traditional riding mower, but it took 4.5 hours to mow everything. My zero turn takes an hour and 15 mins.
