I am mowing 12 acres with only 2 areas that have mild slope. Quite a few trees and flower beds. I am 6'2" and over 300# and need a generous seat. I would appreciate some pro advice on which ZTR would be best for my size and for the long run. I know I am not mowing for a living but I want the best and price is not a deal breaker. I am used to having to pay first class for a big a**.
