I just sold my tractor and will be replacing it with a ztr. After much research i have settled on an exmark. I have 7+ acre of flat wide open property with few obstacles that i will be mowing about 4 times a month. I'm having trouble deciding on the 60" or 72" deck. I'm leaning toward the 72" with lc kawi. The two most important factors are: 1. Quality of cut 2. Mowing time Any thought or suggestions will be appreciated. This is an excellent site with great information. I have learned alot in a very short time! Thanks to all who reply!
