2016 JD 4052 Emission Problem

[Texasmark]

Helping a neighbor. Stop light on the dash came on indicating that the exhaust was sooted up and the operator initiated cleaning process (found in the owner's manual) was unable to effect the repair. As defined in the manual apparently the soot is of sufficient volume to cause the engine performance to degrade.....can't maintain any reasonable RPM level. I assume that the problem is soot collected in the exhaust system. There is a 10" diameter x 18" long (approx.) canister right under the hood and part of the exhaust piping system. I am thinking that the problem is that canister is full of soot. Anybody have a similar problem and fixed it themselves?
Thanks,
Mark

Found the JD online parts site and found the PB for the tractor. I had all the parts (filter elements in the canister in the exhaust line containing the exhaust filtration) ID'd and was going to call JD this AM to check on price and availability.

Got an email from neighbor and he said that he was able to get an appointment with the farm visiting JD tech. He said that had he known I wanted to fix it he would have let me do it. Maybe it worked out for the best.

That sounds the best, wish him luck getting up and running. Hopefully he will learn about his system and what he may be doing wrong. And the tech won't be doing any assuming.
