Just wanted to share this as I think the importance of a good dealer cannot be understated. I took delivery of a LS MT352HC back in February of this year. In general it has been a really good machine and a vast improvement from my old tractor.
Around the 20 hour mark, I started to have some issues where the throttle would rev up/down and then a F31 S29 error would be tossed out and the tractor would go into limp mode. After a few calls with the dealer, the suspected culprit to replace was the throttle assembly. Dealer sent a tech to my house, swapped the throttle. Issue seem to be resolved, but eventually came back on an intermittent bases. Shutting down and restarting would remove the problem and I could go anywhere from minutes to many hours before it would toss the code again.
So eventually I had the dealer come and pick it up. As suspected they could not reproduce the problem...until they were loading it on the trailer to come back to me, it failed. They replaced the throttle assembly again, cleaned and reseated all the plugs as well as verifying good ground connections.
Tractor came home, worked for a period of time and started again with intermittent F31 S29 errors. I had been in contact with the dealer, but due to work, travel and some vacation time I could not get it in for service and I had been working around the problem. Eventually it started to toss an F02 S636 error and I could not get past it. Tractor would run fine for 5 minutes then fail, and no way around other than to let sit for an hour to cool down. Upon a restart I would get the same results and error after 5 minutes.
That F02 S636 error indicated crank sensor error. So a new sensor was ordered. Took some time to get the part, but when it came in, dealer sent a tech to my house to fix. Low and behold, the fuel line was routed wrong and had put pressure on the back side of the sensor. After removing, you could clearly see it was cracked where the wires entered it. 10 minute job for the sensor to be replaced, and tractor was back in action. I put over 10 hours on it and its running like a champ.
A couple of morals to the story here. 1. Have a good dealer that cares about customers and fixing problems. 2. Have some patience as a customer, these systems are so complex these days, tracking down intermittent errors can be difficult. 3. Have faith in the product...all products can and will have issues...doesn't mean its a bad company or product...
