Hello again Trent. I have the gas motor it is alot lighter than the disel and still has plenty of power.As for the upkeep it is just oil changes and cleanup thats about all I have ever done.I havent even changed the spark plug in 4 years.Another thing that I like is I can stand up and drive with no hands steering it with my legs leaving my hands free to spray.The pumps are really powerful to I can set the sprayer up and spray at least 60'maybe more.The throttle is like a lawn mower and you set it and keep the rpm the same to keep the pressure at the same psi for a nice even coverage They even have a cigarete lighter.I want to get it set up to be able to have chemicals in there own jugs have a digital mixer mix the solution that is desired and use water out of the lake and just spray without having to touch nothing but a button and a spray nozzle.Wouldn't that be nice well gota go for now DOC
