I want a new 60" Exmark in spring of 06. I am new to the mowing buisness. I have 48" Lazer hp with a 23 Kaw, but I cut large commerical propertries and residential houses. It takes me too long to cut the large propertries. Here is my questions. Midmount or out front deck? gas or diesel? My dealer is tring to sell me an 05 60" 31 hp exmark. Should I wait for the new deck on the 06 line of mowers and 35hp motor. My largest property takes me six hours to cut with my 48". Thanks for any help.
