SVL90-2 Weight Ratio, v3800 DPF Delete

[super_kev]

Does anyone know what companies offer DPF deletes for the SVL90-2/v3800? I read there are a few users here on the forum but one of them either went out of business or is otherwise unavailable for contact. I just picked up a 2014 SVL90-2 and would like to know my options for getting rid of the DPF when time comes. There are tuning companies out there that will tune these, but I don't want to have to idle my machine at a certain speed to burn stuff off if I trip the timer that requires it.

Also, as I was unloading the SVL90-2 yesterday, I about flipped backwards backing off a flatbed onto a loading dock with a 6" drop from the flatbed. Granted, I didn't have a bucket attached (it's coming) and in hindsight I should have put 2-3' of 4x4s or something there to help gently lower the unit to the loading dock, but it was a good reminder are how rear-heavy this unit is. With a empty bucket (another 1000lbs or so on the front), what's the grade or angle one can drive up without it wanting to tip over backwards? I'm a residential/casual user for cleaning/clearing my land, snowblowing, etc., have driven smaller Kubotas and Cats before, this is the biggest I've used and I'll get comfortable with it.

I've had a 90-2 for a while now, bought it new, I have about 1200 hours or so on it now. The best advice I can give you would be this....DO NOT LET IT IDLE....do not lug it, put your foot into it and run it and regens won't happen that often. Not sure I would even waste time looking for a company to delete it or spend the money unless the delete is bulletproof and you have someone other than a dealer that will work on it if there's a problem. I've never noticed a weight ratio problem with it, I go up and down the trailer a lot without the bucket on and it's never tipped back on me but it sounds like you were coming down a pretty steep angle maybe a little quick. It's been a great machine for me and what I do. Best of luck and be careful, she's a big girl....

Nope, off a flatbed semi onto a long flat concrete loading dock, was backing off. Looking back at it, it was probably more of a 8-10" difference between semi (higher) and dock. Went real slow backing up then felt the back end drop as I passed center of gravity, kiss the dock and the front end lifted a little then came back to earth. Made me wish I had a bucket, that's for sure. But, I'd be interested to see your trailer and ramp combo at which you can drive up without it tipping, so I have a visual in my head as to what's possible. If you stop halfway up the ramp and start again does it want to lift the front end up without a bucket?

I load my JD CT322 (almost 9000lbs with bucket) into the back of a 96" wide deck over axle dump trailer. I back it in up the ramps backwards, and then unload down the ramps forwards. Being a deckover, it's pretty steep so that's how I like to do it (I prefer to keep the weight on the high side). The sides on the trailer fold down, so if I want to haul it facing forward, I just 180 it on the deck once I'm on, but usually I just haul it backwards.

I think this is great advice for anyone running a Tier 4i or Tier 4 Final machine especially with SCR. I only own CASE machines, but the idea is much the same. I have had 4 new machines since tier 4i and three of those are Tier 4 Final with SCR and I have ZERO problems, not one warranty issue. There are companies that struggle with SCR issues with the same models I have. The difference is how you run them. The landscape guys are having problems, the excavator guys much less. We run ours hard ( meaning I work them). If they are on a job that is lighter duty, the idle is kicked up, which is counter intuitive for me but that is what you need to do. If you never work them and get them hot, you will likely struggle, especially in cold weather.

I can see how deleting looks attractive but I think it creates its own issues down the road. That said, Kubota is really dropping the ball and if you cant get support from a dealer or corporate, then maybe your no worse off deleting from a service support position. EPA might have another perspective, but I don't see them sniffing homeowner machines anytime soon.

It's not how you run them...it's how well they are engineered and the quality of the component manufacturer.
I too have a plethora of tier IV final equipment, and every failure has been component integrity. Not a single "my guy idled too much" or did something to interfere with the process.

NoX sensors always get skewed values on my Duramax trucks from sensor internal connection issues. My C9.3 engines have an electric fuel pump that goes kaput.

My cummins 6.7 engines carbon up the tube to the exhaust pressure sensor.

My Cat 9.3 engines plug the tubing to the DPF differential pressure sensor.

None of the above ever occurs more than once every 3 years it so.

Well I wont say that the quality of engineering and components isn't a factor, but when the same models of machines are run by different companies with different outcomes it is obviously not components or engineering issues since they are the same. It also comes down to how they are run with Tier 4i and final.
