I have about a 1.5 acre level lot with just a few obstacles that(since I still have a day job) I mow every other weekend first of April through end of October here in Middle TN. Of course, this would make one ask me why I bought a 52" commercial Gravely XDZ 100 series last fall right? Well, I considered it a "retirement investment" as I will be retiring in October, 2013. I wanted a ZTR(for years:0) and I wanted one that would (1)outlive me....(2)only require normal maintenance and no costly post-retirement repairs.....and(3)an investment that my son(and grandson) could inherit when I pass away. When I retire I'll probably mow more often(weekly, maybe even twice a week) cause it's so much dadgum fun driving these ZTR's so maybe that will "justify" the expense. The only thing I regret about the purchase is that it cuts my yard so much faster......now it's only a 1-beer job instead of a 3-beer job like it was when when I had the old lawn tractor:0)
