I have a 2 ac. lawn with lots of sand and leaves in the fall. I cut the grass at my church which is about 1.5 ac. with the cementary and i also cut a elderly ladies yard that is about 2 ac. . I have a john deere riding mower now that is worn out the motor is fine but i have gone through 2 decks. I am going to buy a z but not sure which one. I have a john deere,hustler,exmark,walker, and a snapper/yazoo dealer near me. im putting about 200 hours a year on my mower.
