I'm buying a Hustler walk behind and would like any of your professional opinions! I have my walk behind narrowed down to the Hustler Trim Star Hydro 36 WB $3700.00 or the Trim Star Gear Drive 36 $2600.00. I am a small 1 person opreation (12 lawns a week) with a few extremely picky clients. Should I spend the xtra $ for the hydro? Thank you everyone for your input!
