Ok here's the situation, I go out of the garage with the mower, ride it to one of my customer's lawns, hit the blades, and nothing happens. So I turned them off an tried again. Again no blades engaging. Did it another time this time for like 15 second I left them on and the blades still didn't turn on. What could be wrong???? The only thing I could think of is I need a new solenoid. Will this be expensive to fix because it is an electrical problem??? Also my left drive wheel keeps getting loose(nuts keep loosening) the right one doesn't do this. I always tighten them good too. The guy who I bought it for I think drilled the whole to make them bigger and oversized them. I now have to buy a new rim and tire for my mower. With all of these problems I'm definitely thinking of selling now.
