OK, so 2 weeks ago I was using my L4330 moving some sand. I got out of the cab while it was running. I got back in and my have flopped down on the seat a little hard and the tractor stalled. I have tried starting it a hundred times. When I turn the key over there is no starter noise. I assume a safety switch (under seat maybe). I checked that safety switch the plastic arm still goes up and down with pressure feels normal. The panel shows the mid-mount PTO dash light but the mid mount was not being used and is not on the reader on the dash will switch between the speed med high to neutral... I called my dealer who said just sit on the seat with the key on and move every lever I did and no luck...... Any thoughts??/
