To find "just the right" lawnmower may I suggest that you begin your shopping at Rabalais Small Engines at 220 Windermere Boulevard in Alexandria, Louisiana.
Rabalais has several brand names from which to choose. Got a big lawn to mow, opt for the zero turn radius mower to help you get it done faster.
I, personally, purchased a 54" cut Cub Cadet riding mower. It takes care of the 3 acres that I have to keep up without any problems at all.
Remember Rabalais Small Engines when you need to purchase a mower.
