The OP was just a mention that a first regen for him was a no event, everything went smooth.
It is after other comments questioning the worth of diesel particulate filtration in general...
I have no interest in discussing merits of clean air with science deniers.
Too many folks seem to feel they should have opinions on things they have little if any experience with.
I do not own a Kubota tractor with DEF, that may change, I do however have that system on heavy equipment, and exactly like taking lead out of gasoline in the 70's we are taking as much pollution out of our diesel fuels as we can.
It didn't happen over night in the 70's and it took Many years of engineering before we came close to getting gasoline engines close to right. With every new generation of gas engines there are improvements, most are the results of mandated change, if you look at the 'excuses' why we shouldn't have removed lead you will see it is the same kind of 'argument' offered today about diesel particulates... The only way we collectively will do anything to improve the future is if we are forced to do it.
I may as well also state the obvious, I also appreciate hearing first hand experience and few on this board have had the experience of actually owning And operating some 20 different models of my favorite tractor brand,Kubota.
I enjoyhearing about new experiences, new tractors, and helping with occasional problems when I am able. There are some that also like drama in these forums, I don't much care for it and have appreciated the owner of this forum doing his best to keep it out... For those in this thread simply looking to 'stir the pot', myself, I wish you would find another place to do it.
And for the OP thank you for stating your actual experience with your First Kubota Regen. KennyV
