Compact Tractor Diesel Particulate Filters (DPF) Version 2.0

I, for one, would buy the tier 4.

They are cleaner, don’t smell, start better, and are quieter.

I have two pieces of modern equipment, and lived with dirty Diesels for forty years. The improvements are substantial, and I would never advocate going backwards, as our conservative friends would propose.

I don't know. I'm a conservative friend in most things and I'm in favor or Tier IV for the cost/benefit ratio. I personally wish we had the luxury of more R&D time before these things hit the market, but I do realize that's not the way that the world works.

If the scientists, politicians, and most of the voters agree that it's high time and even past time to go to Tier IV, then the next questions from a conservative manufacturing viewpoint are simple: Is Tier IV is far enough along in development to be profitable? And are the majority of the customers willing to pay for it? Apparently the answer to both of those is yes, so it's a go.
Pretty simple, really.

Whatever blows your dress up I guess. Best avenue is buy a gasser and be done with it. Cheaper to run fuel cost and less initial cost as well.

Last fall, I purchased a new L4701 after selling my '02 L3000. I started using the new tractor in some very cold weather, within four or five hours of operation it was barely running. I had no experience of DPE and regeneration, I did read the manual but didn't foresee a problem. I got back with the manual and quickly realized I needed to figure out how to run this thing with this new-to-me exhaust system.

Dealer service dept. was zero use. They claimed they knew nothing about any issues with DPE and had no advice. Emailed Kubota [which I've done in the past on two other tractors and received back all sorts of info' and advice]. Zero use, they said we don't know what you are talking about.

Finally, I rejoined this forum [lost tract when I changed email addresses a few yr. ago] and got on YouTube and found all kinds of info. Spent a couple hours learning, tried out everything, and tractor runs great in any weather \.

The real point is, I bought this new tractor at the dealer where I'd bought two others prior to the new emmisions stufff, and I had zero idea there even WAS new emisions stuff. I find it unacceptable that the dealer didn't mention any of it, just delivered the new tractor and cashed my check. Plus the service dept. claimed to know nothing about running the new system and any learning issues with it.

I am quite happy with the L4701. It would have been very nice, and professional, to have gone over these operating differences with me before delivery.

it's DPF. not DPE but no issue. Dealers don't sell anything today over 23 horsepower that isn't common rail, ECM controlled and they all have DPF or DPF and DEF injection if over (I think) 100 pto, so why would a dealer say anything to a buyer because it's the 'normal' scheme of things now.

I'd say (from discussing the current T4 final units with my dealer's head mechanic, that 90% of the issues with the new T4 units come from owners not following the owners manuals concerning operational parameters. You need to actually read the operators manual instead of stuffing it in a drawer and forgetting about it. Kubota (and other manufactures plainly explain that in there. Not like the 'old days' at all. T4 final engines have unique operating parameters.

Between my owners manuals and the Workshop manuals, I rarely have any operational questions about my units, it's all explained in depth in those manuals and I sure don't pose a question on any Internet forum because I don't want someone's opinion, I want hard facts. Hard facts are a pretty rare commodity on any Internet forum (or You Tube) for that matter. Mostly opinions and opinions I don't need.

If you were talking DPE to the service department, they probably had no idea where you were coming from.

Tier IV phased in commencing 2009. Almost all dealer inventory Tier IV by January 2013. Old news in 2020.
You have to get out more.

All 2020 new tractors (ALL) in Europe are Tier V. No exemption for <25-horsepower.

No, I typed it incorrectly. Don't know where I came up with "DPE."

I don't have a problem with the dealership, I've bought 3 tractors and etc. from them over the years and would go back if I wanted another. I didn't realize that this Tier IV thing had been the norm for so long. Been using my 2002 tractor too long, I guess. I know now, and I've been approached by several acquaintences to explain to them how to run their new tractors. I send them to Youtube to one or more of the Messicks videos [I think that is their dealership name...]. I'm so behind I'd never heard of Messicks but their videos are very informative. I'm all up on DPF now.

Couldn’t have said it better myself .

This portion of your "hard facts" is incorrect. Now if you change that to say "these brands" (then list brands) then fine. Some brands don't use common rail OR ECM controls still on their >23 hp tractors. I know Kubota does. And that may be what you were referring to.

I am, all I own actually. Maybe some are not but I don't own any. I believe that has to do with some sort of EPA credit but again not sure. Around here, you basically have 3 choices in tractors, JD, Kioti and Kubota, almost forgot, a Branson dealer opened up, up town, but I have no interest as they aren't big enough for my needs.
