Tier 4 Summary and Comparison

[1stDeuce]

Branson was my choice. The DOC is covered under the warranty and looks like it could fall off after 5 years and not cause any issues as the engine itself is full mechanical.

They also seem to be heavier than most other brands and weight = traction. Not as refined as some of the others, but I was used to older tractors and not in the market for something car like...

It could fall off with no problem... As far as I could tell, the Branson DOC setup is only monitoring backpressure. If the backpressure gets too high, then the light comes on. You run it at rated rpm's or close for a 15 or 20 minutes and it'll clean out. If it doesn't, the DOC can be taken apart and cleaned out according to the dealer. OR you could take a long drill bit and drill about 10 holes through it, and it'll never turn on the light again, no matter how you run it... I'm not so sure you'll be able to bypass the DPF systems very easily in 10 years when they don't work...

After much research, leaning toward buying a Branson 4020R, I got lucky today and solved my tractor dilemma by finding a nice low hour 2003 Massey Ferguson 1455v. I don't think it's even Tier 1, if there is such a thing...

Mahindra pulled a 'Deere' with mCRD and gave a funny name to something that half the industry is using. Its called a 'DOC' Diesel oxidation catylist. Its 90% the same as a DPF but without the particulate filter. It does not have to burn like a DPF, but to avoid creating soot the engine has to run hot all the time. Lots of CNH stuff uses it too, so we offer a lot of equipment with both systems. One is not better than the other, biggest issue is educated operators. Buy whatever tractors suits you best, then learn how its emissions system works so you can care for it properly.

My Workmaster 50 has absolutely zero visible exhaust. Correct me Messick but I think that the emissions systems are warrantied for 10 years?

This tier 4 misinformation is ridiculous. When the tractor is ready a light starts blinking, crank up the rpms till it stops blinking, continue working... After 8 to 10 minutes the light goes off, DONE. Life will continue.

My big thing is not to have electronic injection on a tractor! It'll be fine under warranty, let something bad go wrong after warranty and you'll be looking at big $$$$$$

 

[Turbys_1700]

Whether we like it or not, emissions is here to stay. I don't think we will ever see reductions in air quality standards. Hopefully the Tier 4 final regulations with current manufacturing technologies will prove to be just as reliable as most everything else on tractors. Increased complexity for repairs and higher maintenance costs are possible. I just wish that the EPA would STOP and let these standards STAY so that it can all sort out.

I'm afraid that no politician will be able to reverse any of the emissions standards. With my diesel truck which is Tier IV, it can be a pain unless I am spending a lot of time at highway speeds or towing a load, because when it regens, I have to keep driving until the regen is over. My tractor is not as bad, because I just continue working at a higher RPM and it takes care of itself.

The plus side seems to be that the engineers who make these engines can now adjust things with the engines until they get more power out of a smaller engine as the emissions are not a limiting factor any more.

We have to adjust to the standards that our elected officials have settled for, and I doubt that any of us are wealthy enough to pay congress to change its mind.

Most guys I talk to in the industry are convinced Tier 5 will come, enough so that many of today's DPF systems are already compliant so they can avoid yet another redesign.

Yep.

I run a Tier IV Interim road grader. We are due to trade but are gonna wait a couple years to see how this sorts out.

From what I have read Tier 5 is more a small adjustment, not a huge change like Tier 4 is. From the guys I have talked to they are already compliant.
