i have finally narrowed my choices down to two mowers for my farm. i looked at them yesterday at the dealer that sells both of them. i don,t know what to decide on. i can buy the hustler superz with a 72 inch deck that has 12 hours on the hour meter with the 28 hp efi engine for $8800.00 dollars or the brand new kubota zd 21 with a 60 inch deck with the diesel engine for $9500.00. which would be the better buy? i know that the kubota has the shaft drive and the hydrautic lift. but the hustler can mow faster. my problem is i don,t know which one would be the best buy. i have been reading this site for a long time and there are many experts that do this for a living and i would like their opinons on this subject. i mow around 4-5 acres around my farm so i don,t do this full time. i am 61 years old so this will be my last mower that i plan to buy. for this kind of money i want to get my money worth. any sugestions would be appreciated.
