How many of you have a diesel mower on the trailer? I have looked at them and was wondering what are the advantages of a diesel mower over gas if there is any? I currently run a gas ZTurn 52" TORO and a 44" TORO Hydro walk behind. I like both but, the other day I sat on a TORO Diesel ZTurn and man that thing looks mean and sounds sweet! The price out the door was right at $12,000.00! That kind of money I could buy another gas ZTurn and walk-behind! Just curious.
