Well, I finally purchased my first riding lawn mower. I went with the D-130. Arrived today with the bagger installed. They did not install the blades that came with the bagger so I did. I filled her up and off she went for the next hour it cut through my long grass like nothing was there. I had one last spot to do and needed to move a folding table that was in the way. I backed up a little and then dis-engaged the mower deck and hopped off. Yup, it shut off as soon as my butt left the seat. I have not been able to start it since. Fuel is good, Lights light up bright. What did I did I do wrong? I am so frustrated!
