T4.75 Regen Question

[Thumper & Buttercup]

Hey all,

Been running our tractor quite a bit between last year mowing and the winter
Snowblowing.

We are in full mowing season here and this spring we were up to 140+ hours after
the winter work, we are just over 190+ hours with the mowing and work here.

Now I have not had a regen on this tractor yet, I don't let it sit around and idle, in the
winter I've been preheating the tractor and fluids using a nipco heater and with the block
heater and the nipco my warm ups and just like summer so not a lot of idle time then.

I let her warm up and ease her into work and then I'm at the 1900 rpm area working the
whole time and when I'm done I give my turbo a good cooling and shut her down.

I've called and e-mailed my dealers shop manager a couple times and he said the way we
are using the tractor he does not feel there is a problem.

So what do you guys think, should I set up a couple fans and open the hood and do a manual
regen. My fuel usage is steady with the work I'm doing and the tractor is running great.

Thanks for your thoughts.

If it ain't broke - don't try to fix it.

this.

regen is terrible for everything anyhow. Leave the tractor to manage it, and don't worry about it unless you get limp mode.

You cannot induce a stationary DPF regeneration before the rudimentary computer controlling the regeneration cycle notifies the operator the Diesel Particulate Filter is full of soot.

Service people can induce early regeneration via a computer program.

 

[Thumper & Buttercup]

My shop manual has the instructions where I can induce a regen if needed.

I'll keep an eye on it and report back when ever it decides it's going to clean itself.

I guess I'm doing something right that it has not done one.

if you use your junk hard like it's intended, they don't regen.
at least that's true for most truck diesels with DPFs.

putt around on it and never get the EGTs up and thats when they do constant regens.

 

[deserteagle71]

The 4.75 does NOT have a DPF. Therefore you will never see a regeneration cycle. Your New Holland uses a catalyst system which in effect is constantly regenerating.

Your owner's manual should explain all that.

 

[Thumper & Buttercup]

I have a cummings 6.7 so I know all about regens and def,

But in the owners manual it does state with the tractor set in automatic mode for Regen it will notify me if it
goes into regen with a display on the dash and a sound alert. Tbis is from the owners manual, then it goes
into how to do a manual regen if called for.

Just checking with the New Holland guys with a T4.75 what they have seen.



Particulate Matter Catalyst
The particulate matter catalyst is a device designed to eliminate the pollutant particulate produced by diesel engines
from the exhaust gas. When the catalyst is blocked, the catalyst needs to be regenerated.
CAUTION
Burn hazard!
During the particulate matter catalyst regeneration process the exhaust stack and fixed hood area
becomes extremely hot. Allow area to cool before servicing or working near the exhaust system components.
Failure to comply could result in minor or moderate injury.
C0164A
WARNING
Fire hazard!
During the particulate matter catalyst forced regeneration process the exhaust stack and fixed
hood area becomes extremely hot. Park the machine outside and away from combustible or highly
flammable material.
Failure to comply could result in death or serious injury.
W1346A
The particulate matter catalyst can be regenerated automatically or forcibly.
NOTE: During the regeneration process there may be a smell of burning or "overheating".
Even if the automatic regeneration is enabled, when the level of soot exceeds a certain level, the electronic control
unit invites you to proceed with forced catalyst regeneration.
NOTICE: If, when requested, you do not proceed with manual or forced regeneration of the catalyst, the catalyst's
functionality will be impaired. If you continue to ignore this request, in addition to a considerable reduction in engine
horsepower, the catalyst will be damaged to such an extent as to require it to be replaced by the dealer.
The start of the regeneration process is signalled to the operator on the dashboard's central monitor as well as by
an acoustic signal. The indication is necessary for reasons of safety to warn the operator about the high exhaust
temperature reached during the process.
The automatic regeneration does not affect the engine performance. During the procedure, the operator can continue
working normally.
Under certain operating conditions automatic regeneration might not be completed (engine continuously stopping and
starting, lengthy periods at idle speed) and it must then be repeated.
The start of automatic regeneration, if set, is highlighted on the central monitor. Every 5 minutes appears
the symbol shown on left with the word 徹N combined with a single beep. When the regeneration is
finished the same symbol appears with the word 徹FF?

Thumper,
My 2016 goes into the catalyst grid burn off mode about every ten hours, I’m not splitting hairs with you but it’s a different system than your Cummins ( I have one of those too) and the 6.7’s dpf regen cycles. My dash will show a small puff of smoke and emit a single chime that’s really hard to hear with my hearing even in a cab tractor. The puff comes back on for a split second after five minutes then in another five minutes you’ll get that single chime again and it’s finished for another ten hours or so. And like you I don’t idle for long periods. You think it’s possible you may have missed the chime and the symbol on the dash? If your certain it’s never done a grid burn off I’d sure call the service manager at your friendly dealer and ask him again. Will be interesting if anyone else chimes in here on how their’s operate especially the times between grid cleaning. Good luck hope you get it all sorted out.

I had a 2015 Model T4.75 that would do a regeneration about every 12 hours and I ran it near full throttle all the time mowing pasture. The indicator on the dash only blinks for a second at start, a blink at stop and the beep sound at start and stop is so low in sound you cannot hear it over the roar of the engine. Your unit is regenerating just fine. I switched over to Kubota after having major/expensive repairs on the T4.75 and like the way the Kubota shows me the percentage of buildup in the system all the time and the regeneration symbol stays on during the whole process. On the Kubota I get regenerations about every 22 hours mowing the same pasture as the T4.75. Go figure!

This is some advertising propaganda from CNH and similar to the brochure my dealer gave me when I bought mine Thumper. I had told him I wanted an non-DEF & non-DPF tractor: (much better than I can explain)

Common Rail engine technology with PM Catalyst

The T4.75 PowerStar Series is powered by a 3.4 liter, Common Rail F5C engine with PM Catalyst technology for Tier 4B compliance. Developed by New Holland’s sister company, FPT Industrial, the PM Catalyst is located in the exhaust system downstream of the diesel oxidation catalyst. When particulate matter contained in the exhaust gas passes through it, it is burned off. This filter never blocks due to the high flow of exhaust gas, and does not require regeneration. This system requires no additional efforts from the operator to activate the cleansing process and best of all, the system is absolutely maintenance free, an industry first. To date, FPT Industrial has produced 500,000 engines with PM Catalyst technology and the system has been designed to last the life of the product.

I am looking at 75 HP tractors and saw that NH has changed technology on the new models to be T4 compliant without DPF and the need to regen. I am going with the NH Workmaster 75, similar to the PowerStar 75. First is the no regen, same as the PowerStar. Second is the cab layout fits me better and has an instructor seat standard for the grandson. Third is it is $3,000 - $5,000 less than the PowerStar 75, Kubota M7060, JD 5075E, and the MF 2607H that I have priced. Also NH has 0% for 84 months till 08/31/19.

$46,200 with FEL, third function, 1 additional rear remote for a total of 3, and 2 wheel weights on each side. Will add a WR Long heavy duty grapple and 10 bale hay grapple to the package.

That’s a great deal and a sweet setup. You & the grandson will love it. My granddaughter loves the buddy seat and going on the tractor with papa.

I have 110 hrs on my 2018 Powerstar75 and have never noticed a regen, as mentioned they use a catalyst system, and to this point it has been seamless. I also have 2018 Duramax powered Chevrolet, and like clockwork it regens every 300 miles of mixed driving, will go 400 miles if all highway driving.

Utopia Texas, would mind elaborating on what major/expensive repairs you experienced with your T4.75? If you aren't interested in sharing I understand, but when I hear things like this it's always nice to know just what one might want to be looking out for...

At 220 hours the tractor would not start. With key in on position all the dash lights came on but nothing else. Tractor could be jumped at the starter to run. Was told the PTO safety sensor was out and it was not at the lever, rather deeper in the tractor where one rear wheel had to come off to get to it to replace. Part......$89.......Labor......$2200
Two weeks later tractor will not start. Was told a hydraulic servo was out. Would have to split the tractor in half to repair. Price to fix would be $5100.00. At this point I was fuming. A tractor kept in excellent shape with less than 230 hours on the clock, always kept inside, even had all filters and oil changed at 50 hours which was way ahead of the NH schedule. When I was told the servo was not under warranty that was it for me.
P.S.- What started the frustration for me was that I had previously traded in a one year old Boomer 50 with CVT transmission because it stalled on me twice. Once when I had a tree trunk in a grapple lifted up in a precarious position and the second time when I was slowly driving up a steep hill with a loaded trailer in tow. No more NH products for me!

Well that would be enough to piss anyone off... How could they not warranty a tractor with only 220hrs on it, that's just ridiculous.
