Central WI | Anyone else have the same experience that me and many others around have with the new tier 4 engines in the T8 series. No power, not any better on fuel, etc, etc.
Coming from a Tg series with the cummins, I feel I could run cirlces around the T8 with the TG. We pull a 13 shank disc chisel and a 27 ft field finisher and a 7 shank disc ripper. All three of which can barely be pulled with the T8. We feel we should have much more power and be a tad more efficient, and be able to get in the sweet spot for speed with each implement. They feel like dogs, never recover in rpms, and loose power easily. |

SW Wisconsin | What size T8? We have a 275 and 390 that I feel have good power, pulled a 1300 bu grain cart with the 275 last year and got along pretty well. |

|
| What size tg did you have, how much fuel did it burn on the avaerage. |
|

Central WI | Currently have T8.360, and have a TG275 (that we only use for planting now.)
cummins burned 13.5 - 14 gal/hour and the t8 the same or more under power plus the cost of def. I can get the t8 to burn much less, but also at the cost of doing much less work an hour and only pulling the chisel at 3.5-4 mph. We have always pulled our chisel at 5.5-6.0 mph even with our older geniuses series, which is just right to get that ground turned over. The t8 can do that in certain fields and some spacers in the chisel to keep it up, but those fields are few and far between.
The real kickers is that there have been instances where we hit a spot in the field where it's muddy or real heavy and you can't hit the clutch fast enough before the tractor chokes off, it has absolutely no balls.
Maybe I am asking to much from a tractor with almost 15 years of technology on our 8870 geniuses, and way more "rated" power

Eastern North Carolina | Maybe it ain't got the 360 at the flywheel that it claims... Have it checked...

NW OH | Ours would run fine when not under much of a load, but when you needed power it would fall on its face. Dealer found plastic shavings in fuel tank that would cover and plug the fuel line. We are very pleased with our 330 for power now |

Southcentral WI | New Hollands model/HP numbers vary.....a T8.360 will only run 320 at the flywheel until the HP bulge kicks in, then it hits 360. Deere's 360 is 360 at the flywheel before the powerbulge kicks in, and CIH is the same as Deere, their models represent flywheel HP before the power bulge. Only NH includes the bulge in their flywheel ratings, not sure why. |

South central Minnesota | There is definitely something wrong with it.
There should be no comparison.

Charles City. Iowa | If you Look at Case IH Compare Results T8.360 is the same as Case IH Magnum 315 both rated at 312 PTO. New Holland rates at Maximum boosted engine hp. I like the Compare PTo at rated 2,000 rpm . If you want to wake up that T8.360 I know how to do that. |

East Central, Ga | I believe that your dealer needs to get to work and find the problem! We are not having that problem here, however we have had a lot of rain this past winter and we are finding that the ground subsoil seems to be packed harder than normal. |

Central WI | Thanks for the replies everyone, there are at least 4 t8 series tractors in our area that experience this same issue we have. One is chipped which he said helps but still will fall on it's face, not sure what chip he used though.
We even went with one model larger than we thought (t8.330 originally) thinking we could be a tad more efficient, boy were we wrong.
@ bike accross iowa - I assume you have some chips or a remap or something? Please explain...

Litchfield, NY | Boosted power on Iveco engines is ONLY available when you are running a hydraulic remote function or mobile PTO use. So by the book a Magnum 315 only has 312 at 2000 rpm and 347 at 1800 rpm. As Bikes said a t8.360 is the same as a red 315. I have dynoed 290's that run anywhere from 295 to 298 HP at 2000 rpm. Pulling anything with out PTO or a continuous hydraulic function will never boost these engines. |

Central WI | Good to know on the boosted power thing. Even at 300 flywheel horse, this t8 should rip the teeth off of the chisel plow.
Just disappointed in the performance of such a powerful tractor. |
|
| |
|
Central WI | also....if I put the chisel plow disc (which are on their own remote) on for a few moments, I should get a noticeable power boost? |
|
| |
|
Litchfield, NY | The engine Boost is controlled by a twist sensor mounted in the drive line between the hydraulic and PTO drive. This sensor measures the twist and sends values to the ECM which boosts engine horsepower according to the degree of twist. I would guess any load on the hyd/PTO drive that boosts engine horsepower would be consumed by the hydraulic or PTO load. Just an assumption , as I have never tested the theory. Those size implements would be a real load in our soils and hills here , but if your Genesis and Tag would pull them I cab understand your disappointment. I would check the elbows on the fuel filter , I have found plastic chips in them causing low power issues, as stated by get by. |

|
Central WI | Thanks, I have a much better understanding of how the power boost works now.
First thing I will do is look over the fuel system. |
|
| |
|
| X2 on the plastic shavings in fuel line out of main tank plugging fitting where bigger line is reduced in size. Also-make sure it is not derated electronically from a fault code-your dealer can step you through how to check for them. T8's have slightly different power band than T8000's but our guys have all been happy with power. |

Nova Scotia | you bought a NH |

Central WI | just an update. We haven't had time to do much with it as we are still in full swing. But we did change the pre filter.
taking it out in the field I decided to ignore the computer and see if I could even pull the chisel the speed I need (6mph) which is 10th gear. Will it do it, yes, is it lugged down, absolutely. It runs at 1700rpm 16gal/hr and feels like it's going to die. But it does pull it. For some reason it doesn't seem right. These are supposed to be more fuel efficient, more power, blah blah blah.
With a clogged line, will I still use this much fuel? To me it seems we would run lean. Or is it really running lean but the computer misinterpreting it?
Anyway, it's is going in after we are done with this last push. I will update. |
