I only have 30 mid to small size residential accounts that I carried over from last year. I have a 32" exmark metro that I love for back yards. I want a larger cut for the fronts and larger properties. I am a solo operation and it get VERY hot in Texas, should I spend the extra money on a ZT or is that more of a want than a need? I will be adding more accounts soon and want to make the work as easy as possible. Hydro 52" or 52" Lazer?
