If you haven't bought your new mower yet I would suggest you would save yourself a whole bunch of time, money and heartache by looking at a pro-commercial mower instead of the typical box store homeowner mower. I have had 13 different riding mowers, using them under similar circumstances as yours. 2 years ago I popped for a commercial mower and it is the smartest thing I have ever done. Gravely, Dixon, Toro, Snapper, all have reasonably priced professional mowers. My personal favorite is my Kubota ZD-221, expensive acquisition costs but maintenance is nothing and it will last the rest of my life. It is built like a tank.
