Illinois | I have read a lot of post that mention these 4 wheel drives and make them sound like something to stay away from. I would like to get a 4 wheel drive for under $30,000. Dont do a lot of ground, but would like to do some fall tillage and need 200+ HP to do it. Why are these bad tractors? Any recommendations to use other than JD 8650 that would still fall in or close to that budget? |

South central IL | Like said. Mother deere had a design flaw with the 30,40,50 series. The engine was part of the frame. When the tractor was put in a twist the front axle would bang against the stops and then would twist the engine block. Over time the engine would blow the head gasket and cylinder liners would start to leak. When that happens it is all over . New engine time. I had a 8640 for 7 good years. Last fall the head gasket let go. I ended up trading it off on a 8970. 3 different farmers in my area replaced head gaskets only to have them blow again in less than a 100 hrs. If you get a good one you can get lots of years if you dont. You would have to put a whole new engine in it to fix it and that is not cheap, 20,000 plus. That is why you see some with kinze repowers. If you can find one of them that would be a ok way to go in my opinion . Some may not agree with me. The 60 series was changed and the tractors are good. If you want deere look for a 8560. Same hp as 8650 but wau updated. JMHO |

southwest wisconsin | Just like dairy farmer said. Im an old deere mechanic, and have worked on some of these. it seems once engine problems occur (blown head gasket, antifreeze in the oil pan) its better just to replace with a repower engine. Its upfront cost is expensive, but i thinks its the best way to go. The last 2 8640/50 i repowered are still running, and thats been about 15 yrs ago. If i was looking at buying one, make sure it has a 50 series engine, recent replacement under 1000 hrs on engine. For more money you can get into a 60 series and be way better off if you can afford it, good luck. |

SW WI | According to my Deere rep the problem was in the the 30 and 40 series block only.The 50 series block was made thicker walled to stop the flex action. |

Illinois | Thanks for the information, am I safe in assuming that an 8850 has the same problem or did the 88 series resolve the problem. A lot more power than I need but I found a few for under 30,000 |

Strathcona, mn | Buy a Versatile and then you won't have nearly the issues..... Lots to be had with more HP than a 8650 for the same or less money. |

| I had an 8640 with a new 50 series engine. Head gasket blew on it just the same as the original 40 series engine. The tractor was not abused. Wouldn't want another 30,40 or 50. |

ecsd | Don't even think about an 8850. They had a V8 engine that was junk. They were worse than the 30, 40, 50 series. Most of the 8850's have been repowered, they are ok but if it has the original v8 stay away from it. I have an 8640 and so far it has been pretty good, but it has a 50 series engine. |

Marion,ks | I have two a 1984 and a 1988 both have the orignal motors . The older one has 7000hrs and newer one has 3800 hrs . I run oil anaylsis on them every oil change . The only engine repair has been headgaskets. The older one has went 4years,600hours since and I just got the newer one done they didnt blow gaskets the gasket failed from age, other than that Ihave replaced the injectors and waterpumps. I do not overload them and probaly baby them .The problem is a lot of people pull the guts out of them and then they have trouble it is very hard to find a good one . I only pull mine in C-1 or faster and do not lug them. |

I had a 8450, with the 466 engine. I also had head gasket problems. None of the 2 wd Deeres had
the same problem, of the same age, they will go 10,000 hrs. plus. I would agree with the flexing issue on the block. |

ND | If you are just going to use it for tillage purposes I would go with a 835 Versatile, lots of power, you can pick them up for under $20,000. Just stay away from a 8650 unless you have a big checkbook and like downtime for all the reasons everybody else said. |

north central ky | we have an 8650 with just under 10,000 hrs. it got a complete overhaul at 6600 hrs. and is still going. it has a fairly easy life these days. don't use a drop of oil. |

| You might consider a Case IH 9130. I believe these have a standard PS trans. Which would make a good grain cart tractor as well. Plus your visibility is a lot better compared to the 30 40 50 series. My two cents. http://www.tractorhouse.com/list/list.aspx?ETID=1&catid=1108&am...

Sunburst Montana | I'm in the "stay away from them" camp. But at the same time I can show you and others here several JD 86 series that have given their owners very little trouble. This spring we custom spread some fert for a farm with a pair of 8640s. Both have over 10,000 hrs with just one engine replacement done on both of them and thats it. The JD 30/40/50 series are kind of like IH TAs in my opinion. They will give you good service if you baby them, treat then nicely, don't abuse them, or pull the guts out of them. They can't take the abuse that a Steiger or Versy can. |

south central kansas | this one has over 10,000 hrs has been a good one. Might blow to pieces next time I get it out of the shed I don't know but then so might everything else I own. lol My uncle has a 946 versatile and he has had a lot more down time than I have so far. Not saying that wont change in future. But I have been less than impressed with versatile
