NX6010 first Regeneration at 13.5 hours

RockyNY · May 9, 2015

Thought I'd share my first regen experience. I was out spreading gravel today and the "Regen Underway" lamp came on (the one with the exhaust symbol with a thermometer going through it) with 13.5 hours on the meter. I was expecting this, because I've only used it more than 1/2 hour at a go for about 4 times. Other than that all the use has been short (5-10 minutes) of running at a time and I knew this would clog the DPF faster. Anyhow, since I had Linked Pedal on and the engine was never revving very high, as soon as I noticed the light I moved the hand throttle up to 2300 rpm's and continued working. I had the windows open and right away noticed that the exhaust started smelling strong (needless to say I closed the windows and turned on the AC!) It took about 10- 15 minutes before the light went out on its own. I did not at any time press the manual regen button, it was all automatic (other than setting the throttle higher) and completely painless.

At long last a personal, commonsensical and non-rant description of a situation which will become just a normal part of operating a tractor. Thank you for this. I suspect having to grease all the zirts will still be more irritating than having to deal with regen on my new tierIV.

About 14.5 hrs on mine the other day was it's first regen, like you I was just fixing to remove the tiller and hook to the sickle mower, so I just set the rpms up like you and after about 15 minutes the light went back off.

Rocky, you're using your tractor like I use my tractor. Using linked pedal should not be a detriment to DPF regeneration cycles--especially since I was sold a bill of goods that under normal use, the tractor should regenerate the DPF around every 50ish hours. I popped in a warmer T-stat and haven't seen a regen cycle in over 40 hours now. The tractor regulates its coolant at the same operating temp, but warms up quicker leading to less plugging up of the DPF and regeneration cycles spaced out further.

If you're interested in making the switch, pick up a Stant 48808. It will look slightly longer than stock. I've taken the time to measure everything on my stove to confirm suitability. That said, the new 185°F T-stat's bypass spring is stronger than the stock spring, so take a map gas torch and hit one of the bypass spring's windings to "detemper" the spring with heat. Keep the heat away from the wax cylinder. Don't reuse the existing stock T-stat gasket, it'll leak even with RTV, so make a new one or get a new one. Anyway, observed warm up times are reduced and even in warm temperatures under a sustained maximum load, the temp needle rides right in the middle just like the stock T-stat.

I've been super pleased with the result of the swap and hope others can benefit from my taking the time to find a suitable substitute.

Pretty sure that following Eric's advice would put your warranty in danger. Eric may or may not be smarter than a roomful of Kioti engineers but I have no doubt that Kioti lawyers would have a field day and happily deny coverage if such modifications are made.
