Here's a farming thread. Gotta try once in a while right??
Anyone have any higher hours on a 425 - 500 hp ag unit of recent generation??
Stieger with Iveco, Vers with ISX.
Just wondering what like after that magic 5000 hrs.

[Ache4Acres]

5000hr unlikely anymore

Ole 855 Cummins 10,000 easy

[blackpowder]

Not if maintenance fkd up LoL.
Just had an improper valve set tear out cam and rockers lol.
Honestly, need the newer gen stuff like horse to weight, flat plate and hydraulics.
Tractors have tranny's, diffs and tires too lol. Miss my old Vers except she was outdated.

[Old Cowzilla]

Even my M11 has 8000 hrs and that's not anybody's favorite engine. Don't see why these newer engines should not last unless that emissions system pumps to much crap through . Must be lots of Iveco 's out there now with big hours like custom choppers etc.

Deere because a 520 HP engine is real Hp

With the 600hr oil change interval, it's no surprise if the newer engines don't make 5000hr.

I think if anything the tolerances and machining on modern motors are better than ever. The smog systems are the killers egr's and def systems. Adding a couple quarts or so of gear oil every oil change is a smart move due to the presence of friction modifiers now banned in motor oils due to environmental reasons. According to the truckers forum million mile ISX Cummins with that protocol torn apart look virtually brand new. Without it the cam shafts eventually eat themselves apart. Those same guys also do not recommend synthetic oils however for cold Canadian winters synthetic may not be bad idea.

Iveco's sure run smooth.

Deere has a FIX as FAIL 8 year warranty for 13.5 after 2014, head gaskets/head bolts. Oil gets into coolant. Combines seem prone to it, saw one done at 1800 hours. But 13.5 going way of Do Do bird. Long is of fails. Friend has 12000 hours on a 6.8L 7730, cattle operation. Never been opened.

No shit and the first year or 2 with the big operators doing no maintenance before flipping them.

I just bought a " new to us " 97 Agco 8360 4wd tractor. It is replacing my 77 Steiger St 250 tractor. Have had good luck with the 855 cummins in my grain truck, hoping the N 14 in the Agco is the same way.

We have 13000hr on an 855 Cummins Big Cam in a 936. How can one get rid of such a trusty stead? Never a hiccup as long as she has fuel and can spin er over, she goes.

[agstar77]

Only weak point in the 8360 is the transfer case. The N14 will go forever.

As long as N14's are allowed a good warm up.

Has to do with hp and how often it is used

It is simple, the more power you get out of the engine, the more heat you create and other stresses, the lower the lifespan directly related to how often you use this power.

Chore tractors last forever because max power is used only occasionally.

Todays big tractors that are tuned for 700+ HP are going to be a nightmare for future owners. Pulling big loads with high percentage of hours at max load. Notice that owners of these tuned tractors flip them often. Small farms buying these used are going to get screwed.

Same in highway trucks. The high horsepower pulling super B’s has a way shorter life vs the same engines pulling van trailers.

There is no free lunch

So our 450hp, 15L ISX should outlast 670hp rating in tractors/trucks? Rarely over 1800 RPM, never hard pulls. Deere new 13.6L at 680hp?
