Hi everyone - I was driving my 2017 Cub Cadet Challenger 750 EPS today (they are manufactured by Hisun) when it died on me. It had just started right up - and then as i was driving after about 50 feet the engine just turned off. It was running perfect before it cut out on me. No alarms, no weird sounds or smells. It just turned off. When I turn the ignition key, the starter cranks away and the battery and starter turns fast and strong - but the engine doesn't start. I've confirmed gas flow to the carb - that the fuel filters are clean and clear. I've replaced the spark plug with a brand new one. I checked every fuse with a meter. I have confirmed air filters and airflow are good. But the darn thing cranks away without the engine even making a sputter or even attempting to fire. Is there a kill switch somewhere that could have been tripped? I checked the seatbelt sensor, the brake sensor, and parking gear sensor - all are working and i'm in Park, pressing down on the brake, and have the seatbelt latched when i try to start. but - nada! It acts like it isn't getting a spark. but like i said i put in a new spark plug. I have a feeling there is a sensor or an electrical kill switch somewhere that tripped.

open to any ideas.

If no spark is reaching the plug, putting in a new one wont matter. You need to see if the spark plug has a nice blue spark. If it is really yellow that would indicate a weak spark.

 

Turns out the timing chain came off due to worn camshaft and sprockets. Need to replace $700 in parts.

Never missed an oil change and always used good synthetic oil. The metal inside these engines seems to be very cheap metal.

Pretty disappointing since it only has 180 hours on it and less than 500 miles

 

Unfortunately they are a Chinese product even though they have the Cub Cadet name on them.
They buy large quantities and if a few are lemons so what, at least that is there thinking. Had a cub cadet zero turn mowerand a poorly made oil filter came off while mowing, the oil pumped out instantly and siezed the engine. 2200 for a new engine. They dont make the oil filters even though their name is on them so no warranty. I feel your pain!!
