Considering moving into a 50+ hp cabbed tractor from my faithful TC40D. Tier 4 engines causing me a little concern. My 4 cylinder normally aspirated Shibaura is simple and has been bulletproof. Question: Has anyone gone to the trouble of consolidating the various approaches that the different manufacturers are taking to meet the tier 4 requirements and laid out the pros and cons? As an example. I heard some manufacturers recommend that their tractors always are operated at 2K rpm or higher - really!? Regens, limp modes, fluids, scheduled parts to be replaced, some allow regen postpone, etc. My TC40D has a modern good-old-days engine.....hope I don't regret giving it up (if I do).

The only manufacturer to my knowledge that offers a cabbed non-DPF engine that is Tier 4 compliant in a 50 HP tractor is Mahindra...
All the others utilize DPF's, DEF, and regens...
I opted for a non cab Workmaster 50 that utilizes an EGR and Catalytic Converter...
You may be able to find a Tier 3 cab tractor if you are apprehensive about the Tier 4 options...
Or look at Mahindra...

Thanks for the link - that was helpful. Still learning about this diesel emission control stuff - life use to be so simple. So it looks like everyone other than Mahindra uses a DPF.....no DEF being used like in the automotive world(?). For those using DPF's, are there any unique ways that the regens are happening or being managed? As an example, a LS dealer told me that if the regen light comes on and you were in the middle of a chore, that you could hit a button that effectively is a wait-until-later button. Are any manufacturers having more or less issues than others? Thanks for your input.

New Holland stated that you can continue to work while it does it's thing. I have not experienced the process yet (4 hours in on new tractor) but I will let you know when that happens. Maybe this weekend. :thumbsup:

It's one of the reasons I bought a Mahindra but to tell you the truth the dealer had whole lot to do with it too. While I could have bought a NH from the same guy I figured the Mahindra Mcrd was better than a DPF machine. It seems to me that Mahindra took the design approach to meet the requirements while the others just slapped a bandaid on it.

Branson offers a 55 HP Cummins with a DOC. Still has mechanical injection.
After reading the LS and others most people just keep working their chore right through the regen and only notice the light.

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...

85 hours on my TYM with 1 regen. When the light comes on just keep working. You'd never know its doing a regen if the light didn't come on.
