Question about Craftsman 17.5 hp 42 in. Deck Lawn Tractor - CA Model
I have a Sears Craftman Rider Model # 917.273403. I just replaced the safety seat switch which I thought was the problem and to no avail. what was happening was it seemed as if when it warmed up about three passes around area it would seem to quit then power up and then quit. This always happens when I am at or on the slightest downward incline. It always starts back up but if I do not get to an incline will just repeat the dying and then make or three passes and do the same thing when hit the decline. I have checked the carb, and the fuel filter, new gas, etc. All plugs and carb cleaning was done at the end of last years season. I did have to buy a new battery and after installed mowed the entire yard 5 acres with no problem, Next time then it began this business with dying out. Do you have any suggestions or clues as to what this could be and how do I go about fixing it. Thank you.
Interesting, The only thing that is changing is the angle of motor and carb when you hit the incline. The only possible culprits therefore would seem to be an oil sensor cutoff that thinks your oil is low low when on the incline, you didn't list oil as one of the things you checked. Or an out of whack float on your carb. Nothing else on the machine would be that sensitive to a slight incline...

Most of those mowers have a seat sensor. Some are faulty...When going downhill, it's possible that your body weight shifts forward and the sensor is turning the engine off. To check this find the sensor and temporarily bypass it and see if the problem persists. It is a safety item though so do not use it bypassed...replace the switch.
