Regeneration Mode

[Tractor Tom]

Kioti's for 2015 are Tier 4 engines that require a Regeneration.

Thanks for that, kanook, what part of eastern Ont. are you from, if I may ask.

Carp / Almonte area.

Well, I am; still, considering a 3350 and if the regeneration system on THAT PARTICULAR MACHINE requires that it be paused from work, Kubota has lost a sale for sure. That is intolerable! If I can keep working at full output, then OK. I can just see me now stripping all that crap off the machine and installing a normal exhaust. My current compact utility tractor is 33 years old, worked hard, and has NEVER been back to a dealer. If I can't service it, I don't want it.

The manual for my 4701 says to keep on working and if the RPMs aren't high enough a light comes on telling you to increase the RPMs. I think it will just fine.

So your saying "the machine' is telling you how and what to do. I love it.

And you have to pay more money for that "luxury".

Maybe they will start making gas tractors again.

Yup, Isn't it great!

The DPF is never a requirement. Only the emissions are regulated. If an engine can get to the required levels by some other method, they do not need a DPF. There are trade-offs, one being engine life. High combustion temperatures burn the soot particles, but those high temperatures are tougher on engine components and produce higher NOX. The catalyst reduces the NOX. Kubota has said their new engines sold on the commercial market (no DPF) are not suitable for their tractors. You can find several no DPF tractors in the CUT class. Possibly they will be best for many customers. A lot of people talk about running their tractors at low engine speeds which translates to lower power output and lower engine stress. Time will tell.

You are absolutely correct MHarryE...It's what comes out the pipe that counts.

I think the reason a lot of the CUT class is non DPF is that they are under the HP requirement specified for mandatory (26hp). My B2650 is rated 26hp and thus just slips under the wire. Seems a bit of overkill for diesel tractors that typically operate in the great wide open in a space that would be occupied by thousands of cars if in the city. Now if all those commuters were going to and from work each day in/on diesel tractors, I could see the point of it all.
