Compact Tractor Diesel Particulate Filters (DPF) Version 2.0

[jyoutz]

From 2020 and on, all new tractors sold, have to have emissions control systems on it. There are still some exceptions for the old stock but after that, there is no other way around.

It should also be a matter of time till they come up with yearly inspections on tractor like they do on on-road vehicles.

In order to do that, tractors would have to be licensed like vehicles. I don’t think any state does this now, and enforcement would only be doable with tractor sales at businesses.

^^^^AGREED !!!

I’m buying a new tractor to get the cleaner emissions. I hate smelling the old school diesel exhaust emissions.

 

[jyoutz]

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.

Yes, the old school dirty diesels give me a headache if I operate them very long.

 

[jyoutz]

My bone of contention with DPF in general is, at some point in the unit's lifespan (unless it blows up early in it's life), the owner (whoever that is, maybe not the first owner and maybe not the second one but at some point in time, that DPF canister will have to be cleaned or renewed and they aren't cheap to clean or replace and the onus will be on the current owner not anyone else and not the factory either.

I've dealt with that exact scenario in Class 8 T4 big diesels and just to clean one is over 300 bucks and been my experience that many are not cleanable and must be replaced. The big ones are 500 + to replace.

$300 seems cheap for ten+ years of use.

 

[jyoutz]

I don't think anyone WANTS a less clean burning engine.
But what we don't want is systems/components/sensors that are prone to fail and that basically puts a tractor or vehicle in a limp mode or worse, shuts it down requiring we haul it to a dealer or even worse, pay extra for them to come get it, when they can.

Then there is the additional exorbitant price to have the system/DPF cleaned or replaced every x number of years.

At the prices we pay, they should use more reliable parts that are less likely to fail coupled with better prices for these parts/sensors when we do have to replace them. Include troubleshooting guides and better diagnostics for us to be self sufficient when they fail.

How often do they fail? I haven’t heard of one person in my area who has a newer tractor say they’ve had a failure. People said the same thing about automatic transmissions and electric windows in vehicles, yet they are very reliable. DPF is also.

 

[jyoutz]

My diesel ownership has been confined to one diesel VW Rabbit, one John Deere diesel tractor and two Kubota diesel tractors.

Were you physically coerced at the Chrysler dealer?
Or was your choice of a Ram truck voluntary?

My Dodge Ram truck with Cummins has been completely trouble free for he past 150k miles.

 

[jyoutz]

Like as been said before, there are lot more differences than just engine RPM.

For one, the L2501 uses a mechanical injection system, while the L3301 and up uses a Common rail system.

The engines are different but he tractors are the same.

I'm on a few tractor pages on FB and every couple weeks some one is dealing with an Emissions/DPF/DEF failure, so it is too common.

I'm on a few tractor pages on FB and every couple weeks some one is dealing with an Emissions/DPF/DEF failure, so it is too common.

I am NOT on FB (and never will be [that or "Meta" (FFS!)). Would you provide some more data/info on what they're stating? I mean, it could be just a handful of folks repeating the same thing (it happens here and just about any place). And what does "failure" mean? Who diagnosed?

I'd guess that the bulk of the issues are with the DEF components rather than with DPFs. DEF pumps and people putting in crappy fluid or the wrong fluid are common things that I hear (I know a mechanic who services a lot of different equipment and talk to him about stuff like this).

DPFs are mandated to be covered for a certain amount of miles/years?/hours. As noted (and I was aware of this) they CAN be cleaned (there's confusion here as to whether that's expensive or inexpensive- I don't know; if lots of this was happening I'd think that the cost would be more widely known). Somewhere along the line I picked up on the notion that it was 3,000hrs for tractors. No idea whether a plugged up one prior to this time is considered covered under this warranty or not.

My Kioti has a DPF. 715 hours and about 5 years. Absolutely zero engine or emissions-related issues: I've been pleasantly surprised at how well it works.. I cannot say what the frequency of regens is other than it's not so frequent that I actually can state how frequent it is: no doubt I KNOW when it's happening, but when it is happening I am usually working or have additional work to do. I can, therefore, only speak from my single data point that DPF systems have not been an issue for me at a higher than low-use level of hours. And from what I know of such systems (having done a lot of research when looking to buy a newer, used diesel truck) most issues were sensor related (not to diminish the fact that some sensors are stupid expensive, just that the DPF filter itself has not seemed to be an issue point from what I've read/seen/heard).

Still wrong no matter how many times it gets posted.

Different animal, you have DEF, smaller tractors only have a DPF. I believe you have to exceed 90 pto to have DEF on a tractor. Got a buddy with a newer King Ranch who has his DPF plugged up and has to be replaced. Issue is, across the board there are over 150 on back order so he ain't the only one. Not driveable, motor has derated.

 

[5030]

$300 seems cheap for ten+ years of use.

Kubota claims 2500 regens before replacement. None issue with me, my units are pre 4.

Keep in mind that is the cost presently, not in the future and it don't include labor.

My Cummins is pre-DEF

You didn't state the year and I'm not a mind reader.

 

[Snobdds]

My Cummins is pre-DEF

Then why are you equating that to a Tier 4 tractor.

They are completely different animals.

 

[jeff9366]

L2501 is one of Kubota's highest unit volume models. It is also a legally dirty bugger.
Kubota's L3301 is the same tractor with eight additi onal horsepower and requisite Tier IV paraphernalia. Your money, your choice.

The claim that an L2501 and L3301 are the same tractor with different hp levels and engine management systems is false.
You really need to check on some of the stuff you post here. Many folks have the mistaken impression you don't post falsehoods.
An L2501 meets the same emission standards as any machine in its HP class. The insinuation that it doesn't is misleading at the very least.


Close enough for a complete tractor neophyte seeking guidance.

You loose sight of the forest for the trees........besides being sanctimonious.

Close enough for a complete tractor neophyte seeking some guidance.

One of the few things worse than being wrong is being unable to admit to being wrong. Tractor "neophytes" deserve the best guidance, not a bunch of inaccurate generalizations. Those that seek tractor knowledge seem to think you are well informed. Some of us with more experience than you do pay attention to your comments.
There are several significant differences between an L2501 and an L3301 aft of the flywheel, the most significant have been documented here.
Step up your game.

 

[jeff9366]

The L3301 isn't the same tractor as the L2501 with just 8 additional horsepower and Tier IV emissions.

According to tractordata, they are both Tier IV.
The L3301 has a 1.8 liter engine.
The L2501 has a smaller, 1.6 liter engine.

Certainly both are Tier IV compliant.
Tier IV exempts tractors <25.4794 horsepower from Tier IV standards.
The L2501 is dirty.

 

[jyoutz]

Nope. Both have DPF and no DEF

 

[RickB]

Every off-road Diesel engine has to meet the emissions limits for the horsepower range the engine occupies. None, including the engine fitted to the L2501, is exempt.
