Kubota vs. John Deere Tier 4 Engines

[hayman5555]

I'm looking very strongly at a Kubota 7060. The 7060 has a Tier 4 engine with the re-gen process. My neighbor bought a JD 6130D about 2 years ago (maybe 3) and it does not appear to have the re-gen process. In fact my research shows that it is a Tier 3 engine.

Does anyone know if this is true? Is Kubota that far ahead of JD, or does JD have a better engine for emissions?

I'm somewhat concerned about the re-gen process and on-going maintenance. I'm planning on keeping this tractor for many years (I've had my current one for 15 years).

Thanks for your help!

All of the manufacturers of engines above a certain size have had to meet tier 4 standards, but 3 years ago they were all on tier 3. So if you are looking at new tractors in that size range they'll all have some kind of devices added to reduce particulates and decrease toxicity of gases. But there are 4 or 5 different strategies to do so, so check out each model very carefully and not just the brand. Some of the modifications have caused troubles and some not so much. There is a thread at the top of the Tractor Operating forum with some user experiences with different Kubota tier 4 models. I have the impression that the tractors with big engines have fewer problems with the dpf's and regen cycles, and some of the brand new big Kubotas use DEF instead, like some of the newer trucks.

Just look for a M7040 used. It will not all Tier 4 problems. I love mine.

My dad bought a new, old stock JD5065E that is tier 3. There is no doubt in my mind that if I were shopping, I would either search for a NOS, or a clean used tractor. Too many issues with the tier 4 stuff, and it sure seems like a hit or miss having a Kubota dealership that is competent to solve the issues- they sell tractors, but are barely capable of doing extensive diagnosis or work.

Reducing tractor emissions has been set in place by President G.W. Bush and is making it's way to reality. Tier 5 in future? Probably. It's all new to us (and them) and you know how we like change... How I see it, there will be problems when they add emission controls on an existing motor not designed for it (cheaper). When the design incorporates the emission controls they will be much better. Example, when def was required on diesel pickups Chevy had a lot of problems because they just added it to their motors (a 20 year old design platform). Ford had that system designed into their new diesel and had little to no problems. I agree with Sheepfarmer; they are all trying something different and one will be the model of the future, but which one.. It will get better but with time. I would find new old stock if you can for now. Lawnmowers will be next as they are going down the HP scale. This is a good read. http://www.farm-equipment.com/blogs...f-the-curve-small-tractor-oems-embrace-tier-4

Little to no problems in the new Ford Superduty diesels?

Can I buy yours, LOL.
