8970

Dioes the 8970 have a cummins engine in it ?

 

[Farmboy169]

Yep, it has a N14 cummins

Didn't John Deere have the 13.5 liter at that time?

Yes they followed Jon Kinzebaw lead and finally put a real motor in their 4WD line.Jon Kinzebaw has forgot more than many highly paid engineers that have never farmed know.Unfortunately the bulletproof older mechanical engines [Cat& Cummins that worked so well were replaced by the new computerized ,pollution friendly,urea burners that require a computer to tell what the codes mean.The new semis are also that way and getting worse.I had a new Ford 6.6 urea burner that was great until the check engine light comes on and it depowers itself to about half.It has 30,000 miles and it has ran that way since new and they cant seem to fix it.So I am getting a new Dodge with Cummins with out urea.

cummins not that great eather they had a lot of inner coolers that lecked . antia freeze in pistions. on the N14 not good for long life

We ran one here for 5 or 6 years,it liked the fuel, and we had trouble keeping the AC working, the air box system for the AC was not a good idea, we traded to a couple 9400's more power, less fuel and the AC has been trouble free,,but I did like the Cummins engine...even if it was a bit thirsty...

I had a 8960 with 20.8X38 tires. No power, so I put a 400+hp pump on it. Also had to change the air intake to get more air. Ran great but coundn"t ride it because of power hop. I traded it for a 9400 with 800/55/42 trelleborg tires and rear weights. It weighed 50K. It was a 4 wheel drive 6030, that took all of it"s power to pull the weight. Sold it and the guy put a chip in to up it 65hp but has not run it since. I think the Detroit clone is like everything Deere does in their back engineering. I ask Kinze about putting a real 12.7 in it but was too much to do it. Here in CIL, Cat is the big horse but have head pasket problems. Very high $ upkeep and trade off.

We had one for several years. Biggest complaint was the air conditioning never did work worth a darn. The engine liked fuel and the electronics were always screwing up. We actually took them off and put a mechanical governor on it. I think ours had 9800 hours on it when we got rid of it. Now we have a 9520 and it's 100 times the tractor for having the same power, tons more torque!

There is nothing wrong with computerized engines up until Tier III. They use less fuel and start easier in extremely cold weather. Some of the Tier III are causing issues but it is usually simple stuff. The engines that use urea in tractors actually run pretty good because it an engine that is back to Tier II specs with the addition of urea. Alot of them are running around and everyone loves them. The engine that you just spoke so highly of in the 8970 is computerized to a point, bet ya didn't know that!!!!!! And the computers on that were actually 10 times worse then the ones on our tractors now!

Mainly coffee shop chit chat here.

The 12.7 Detroit was a million mile motor and was pretty much all computerized.The world is a better place because of computers.A fellow bought a tractor from me who has worked for JD for many years and his job is to find out the reason certain engine failures occur and I learned several things that were very interesting.Our experience has been the code shows up and you have to call the dealer.

My road tractor has an N14 Cummins in it, 750,000 no problems yet....and yet could be the operative word.. they were a million mile engine also..
