Please help me explain why someone should buy a non-DPF tractor.

[Grateful11]

They have been looking at a Kubota MX5100 or an MX5200. The 5100 supposedly only has an EGR and is interim Tier 4, the 5200 has an Common Rail and a DPF and is full Tier 4. The 5100 has an EGR but not sure if it has the Common Rail stuff. I'm no diesel mechanic and they make me research all this stuff for them. So could someone explain to me in "layman's terms" so I can explain to them why it would be better to get the 5100 over the 5200 or is going to make that much difference, I think it will because of all the Regen stuff I've been reading about. There's about a $3000 difference between the 2 tractors. They are wanting Hydrostat, Skid Steer style Loader, 3rd Function, and at least one set of rear remotes and thinking about going with R1's over R4's like they have on the Kubota L3940. They need another small loader tractor.

BTW: It's taken me days to find what few MX5100's are left out there. Most dealers don't want to let go of what they have for transfer so we may have to go a ways to get one. One dealer in Ohio has 5.

The Tier 4 (final) engines are nothing more than tree hugger pacifiers. You pay a whole lot of money when you make a greenie-weenie smile.

If you can find a Kubota with an interim Tier 4 engine, or something built just a couple of years ago, you'll be very happy with it. There's no need to spend the extra money on the Final version of the Tier 4 engine, nor is there any reason to have to shell out the extra bucks for the DPF (Diesel Particulate Filter) when doing your routine maintenance.

Hope this helps.

There are multiple reasons as follows:

1). Common rail inection systems are more sensitive to water and dirt. CR requires high quality and water free fuel. Smaller storage tanks commonly found on farms are notorious for water and dirt contamination. The old, lower pressure mechanical full systems have a higher tolerance for poor fuel. Coupled to a lower replacement and repair cost for the mechanical, the CR becomes less attractive.

2) DPF is a long term headache. They eventually clog, even with regeneration cycles.
Most designs call for under 300 millibar restriction for optimal performance.

3) EGR systems add more complexity. They often clog, the valves fail, and the cooled types can crack, leaking coolant or exhaust gas or both. I understand the 5100 is so equipped, but because of the grief these systems cause some people I figured I might as well add it in.

The skinny is; these systems add more failure points. We have not begun to speak about DEF systems, their tanks, mixing valves and selective catalyst components.

Reliability is going to be an issue. I am not familiar with the 5200, so some of these components may not exist on them.

For the record I don't hate the ideas behind the systems. My issue is their durability. Many systems were rushed or they are poor copies of terrible designs to begin with.

My simple way of looking at it (and explaining it) is that the MX5100 is tried and true and, as far as I know, there are no known bugs with it.

The MX5200 may turn out to be the greatest tractor ever in the history of ever, but the simple fact is that you're buying "Version 1.0" of a new system that hasn't had sufficient field/use time to have any bugs worked out of it.

Personally, I wouldn't want to pay a premium to be a beta tester for a Tier 4 system.

I think Pappy has said it best. Why would anybody want to spend extra money for a tractor that is not tired & true and is assured to have problems that are always going to be associated with the introduction of a new and more complicated model.

I got one of the very last M6040 that came into this part of the world and am so glad I didn't wait for the M6060.

Listen to what we are telling you, Grateful11, you will be very glad you did - on down the road.

My God - I hope "they" realize and appreciate the work it took for you to find an MX5100.

DEF systems in Class 8 trucks were prone to freezing up in deep cold winters until heaters were installed in them.
DEF is just one more thing to buy and check when you fuel up and one more thing to screw up when things don't work properly.

I have the MX 5100, pre tier iv. It is a beast and just a great tractor over all. I also just bought an L3301 tier iv. Only have 3 hours on it, so can't report on the regen. The dealer assured me I will probably never notice the difference. Here's hoping he was right...View attachment 414080View attachment 414081

Does your MX5100 have an EGR?
Thanks

Somebody out there,will soon delete the dpf on a tractor, right?

Swlman2,

I'm sure you're right.
