L6060 & baler regen

[K5lwq]

Ops my bad. It was early in the morning, still warming up and I might have misunderstood.

I've read a lot on DPF and all that comes with it. I've always read, that DPF likes a steady RPM and load to regen properly. I'm wondering if the loading/unloading of the engine when the baler strokes causes it to plug more due to that extra load/fuel/exhaust gasses when stroking.

This is what we are thinking as well. But still the baler should not be loading a 60hp tractor that hard either. I would not think the governor is opening on every stroke but maybe that is the case. :confused3:

That along with lesser quality fuel would also cause that.

We can get 3 types of diesel here, premium, regular and simple. The simple one is the cheapest with little to none additives. Once I had to fill with this simple diesel and right away noticed an increase of regens and less performance.

This could happen on the L6060 too but wouldn't be very noticeable on the M7 because it has a lot more HP.

Again, just kinda brainstorming here.

That is a good point. Could be a fuel quality issue.

I would like to pull his baler with my Branson one time but it would severely cut into his production time. I would have to go very slow and stop 3 times for every bale just to blow out the radiator. :laughing:

My M7 has a power meter. Baling is roughly 10% to 20%, loafing. I’ve never had a regen while baling - not a lot of hours at that job. It regens every 13 hours when disking. The M7-171 with KVT will run at 100% continually varying the transmission so the engine is working at its peak. Yes, I can run less power, get mor life from the tractor, but I’m 74 and I expect the tractor to last longer than me in any case at the rate I can rack up hours between several tractors. If I run it at 80%, I can get 18 hours between regens. This is quite different than the L6060 that stretches out regens by being run hard. The M7 does not have a governor in the old mechanical sense. It has an electronic speed control with speed sensors monitoring the engine speed and the engine ECU signaling the injectors to inject the proper fuel shot, actually multiple shots, at the right time. But both of these tractors have common rail fuel injection systems I believe supplied by Denso. I’m surprised it will allow overfueling the L6060 at each plunger strokes but it appears that’s what is happening.

Incidentally the change to farming came 10 years ago. My previous job was validating Tier 3 engines with new common rail systems, then starting Tier 4. Therefore this DPF plugging in only 2 to 3 hours is surprising to me as I’ve never run into anything like it but I never had to contend with baler surge. Kubota surely has but maybe not on CUTs.

Your background explains why you take a very analytical approach to the L6060 DPF issue. I do diagnostic testing and repair on diesel pickups using a SuperFlo chassis dynamometer for loaded mode testing, I have been testing common rail diesels for almost 20 years, the 2001 GM trucks were the first on the market and I was testing them in late 2000 for under load issues. I have discovered fuel system problems on some Kubota products, any chance you have been involved in an fuel system issues?
