Tier 4 Emissions delete

[YakimaJack]

I have a 2014 LS 4046 (first year of the tier 4 emissions) and we have had nothing but problems with it. First off the Emissions regen/burn kicks on and takes no less than 20 mins to complete its regen/burn cycle during which it uses lots of fuel. When new it kicked on periodically...now (5+yrs later) it kicks on much more frequently (and its never at a convenient time). Oh and if you try to continue to using the tractor it has reduced HP. Additionally it has had to go in to have the ECU replaced and twice for DPF/CAT injector failures. I spoke to my LS dealer about my frustration and he said that the first year of Tier 4 are problematic.. but that its the same engine as the Tier 3 and the Tier 3's are as reliable as rain and the new systems are good as well as they don't use the DPF/CAT burn system anymore opting instead for a DEF injection instead, so sorry. His advice; "you just need to avoid using it at low RPMs...which we do now (with marginal improvement in burn cycles) and seems counter intuitive to the purpose of the emissions controls purpose as you are now just burning even more fuel, wish I'd known all this before I bought a 2014...
Anyway I happened to speak to the chief mechanic and he said that the tier 4 emissions system could be 'deleted'...but he could not/would not do it. Is there anybody whom has done this or has any information or details as to what / how to go about bypassing and or deleting our tractors emissions BS.

I don't have an LS but if I was looking to delete one I would look at the DPF and look for any sensors on it and Identify them.
Could have pressure on each end of the dpf and or temperature sensors.
Depending on if the sensors are in the dpf or the piping before and after would factor into what to do then.
If they are in the actual dpf then after carefully removing them and identifing the threads they are using,
fabricate a pipe that would allow them to be reinstalled in that pipe and install that pipe in place of the dpf and run her and see what happens.

You need to find a different dealer. There never were any Tier 3 engines in the less than 75 Hp category. Since he does not know that, what else does he not know?

Several on here with same vintage tractors with DPF and getting along fine.

I know the dealer you are referring to.

As of yet, I am not aware of anyone successfully deleting the emissions on your tractor or mine. Most of the problems I have heard of, are with the ECU. There just is not a work around that has been released for our tractors... yet. And may never will be. The really big boys, like Deere, people can crack the 'code' and 'hack' their computers because there is more $ in that. Our little LS brand tractors are just too small potatoes for these "hackers" to bother with.

I think the mechanic told you the same thing to me when I asked. Mine is still under warranty, but will come off at some point. I am guessing he says "there are deletes but I'm not gonna do it" just to appease you. He is a good guy, very smart and talented. Finding a dealer with the computer software to attempt to do what you want, is probably not going to happen.

No dealer will. It's a Federal crime to do it. I see the EPA is coming down hard on the pickup truck tuners that crank them up and delete the emission hardware and software. Big fines, big enough to put them out of business. Your dealer or any dealer isn't about to dance that dance.

Glad mine are all pre 4 but if I had one, I'd just live with it. Price of progress I guess.

What does exactly the ECU run on the XR4046? According to TractorData, it uses a mechanically injected Shibaura engine, so technically it shouldn't need an ECU to run.

Sounds like some Oriental dish that guarantees heartburn.

I am amazed at the number of people that are afraid to modify something on a tractor,
I would have assumed incorrectly I guess that most readers and user would have had a bit of hot rodder,
or tuner and be willing to experiment a bit especially on something that was giving them problems.
Seems like many might as well just lease and have the dealer do every thing instead of buying a tractor.

Instead of keeping pointing out that you have a pre tier 4 tractor that 99.9% of the time contributes absolutely nothing for the threads, you could really work on your knowledge... Or lack of.

Shibaura is a very well known Japanese manufacturer. Some of the biggest tractor manufacturers out there have been using Shibaura engines on their tractors for a long time, like New Holland and Massey Fergunson.
