Ok so today marks a new issue with the 52". I got the first lawn done. Go to start it to put on trailer I hear a loud pop like backfire and now I have no power. Engine starts blades engage but no throttle. Any ideas? 3 issues in 1 month...pto switch, a week later hydro belt, week later this. I just got the mower all tuned up. I'm beside my self. I understand the switch and belt are maintenance issues but man too much down time.
