My Hustler Dealer is fantastic, so regardless of other brands, my Dealer loyalty says I'm ordering a 48" Trimstar. I just can't decide between the Hydro or Gear Drive. What's the pro's & cons. I'm used to a Toro 52" with sulky & it was fine. I am unable to test one, so your input is crucial to my decision. My wife will likely be piloting this unit & demands a stand up machine. Her back cannot handle sitting all day on a zero turn no matter what I do. 72" Super Z, Suspension seat & Flex forks are a big improvement, but not enough.
