SW Illinois | we have one of each. one nearing 7800 hours the other near 7000. basiclly the same tractor as our 8770, just newer cab and engine.
Would suggest greasable steering cylinder pins, we switched ours out after trying to rebuild a cylinder.
Had to replace the engine/tranny coupler... one on the raod, other we did in shed before it went out.
water pumps are a pain to change compared to our case, and if one idler pulley goes out, it will take both serpentine belts out.
No major issues that aren't present on the 8770... just nicer to operate |

ND | Replace the water pump sooner like 2000 hrs for peace of mind. |

West Chazy, New York | There is a cup that separates the injector from the head. It has been problematic in that the seals fail and allow fuel into the coolant. If they haven't been replaced it is only a matter of time. Not a terrible job, but takes several hours and a special tool. If the gudgeon has bushings they will fail. The replacement will have bearings and is a much better system. Requires separating tractor to replace and is an expensive part. Look for metal filings around the pivot point. If it is left go too long it will be a major repair expense. I once saw one that had been ignored so long the tractor had a noticeable swayback from the wear. High hours wear out the isolators for the cab which makes it noticeably louder. Easy to replace. |

Southern Alberta Canada | We have a 9400 and an 8970, I think other than the transmission, axles and engines on smaller tractors they are totally redesigned. The newer series use load sensing hydraulics, John Deere finally gave up on that goofy steering system on the older series, cab, body and frame are completely different, I don't think the newer series were available with cable operated remotes were they?
The 8970 has allot of electrical bugs that the 9400 has not had yet.
The 8970 shares hydraulic oil with the axles whereas the 9400 shares transmission oil with the axles, both systems are haywire in my opinion but that being said they both work. The hydraulic reservoir is a little small on the 9400.
They both have that goofy rubber coupler at the back of the engine, I'm thinking of upgrading to Versatile type spring coupler the next time they fail.
I prefer the 9400 over the 8970 as it's a quite a bit nicer to service and operate but they both are decent quality tractors if you take care of them. |

Peace River, AB, Canada | Yes, injector cups is a pain, when it happened to our 9300 , dealer told me how many hours was on the unit. He was less than 200 hours off. Inspect new cups too before you put them in!!! Dealer put them in but one went in hard but he said it was fine, asked mechanic if I wouldn't have trouble soon. Double asked again and guess what? 5 hours later injector came out, broke the bolt and injector. Filled up crankcase with diesel in no time!! Caught it in time to shut it off.
conclusion: cup was not finished in the factory and dealer treated me good. |

south central kansas | I really like it. I've had it for 5 years and really not had any trouble with it. I rebuilt the hyd pumps and clutch but not sure it was necessary. The biggest gripe I have with it is there is no way to have a rider of any kind.

| For what it's worth, here's current scoop on JD 9300 and 9400 4WD tractor values:
Avg. Auction Price on JD 9400 so far this year = $57,397 (High $107,000; Low $29,000)
Avg. Auction Price last (11) JD 9300 sold = $52,627 (High $100,100; Low $20,700)
Hope this data helpful! I have attached a pic of the JD 9400 4WD sold for $107,000...it had only 540 "1 owner" hours on it, sold on consignment auction in southwest Minnesota on 3/25/17.
