Seaforth, Ontario | Been thinking of trading up from my 9610. Was wwondering whether to go to a 9660, 9760 or 9860. They all seem to be comparable price wise for for the same hours. I'm not scared to go to a bigger machine than I need but is there something with the 9860s that I need to look out for? A new one can't be justified. TIA |

Wheatley, Arkansas | The 12.5 engine in the 9860 could be more expensive to maintain than a 8.1 in an older 9760, but you would have more HP. A 9660 will probably run circles around a 9610. |

Seaforth, Ontario | I will add that I sometimes run with a 9660 and the only time a 9660 will outperform my 9610 is in corn. In wheat and soys we run the same speed and same capacity both with 30 foot flex. As far as the 630 cutting better thats debatable. |

SE ND | Not a deere guy but I would say its going to depend a little on the crops your doing along with the amount of crops or desired header size. Do your crops require more hp or would the cleaning area be the limiting factor?? If so I believe they are all the same size cleaning area just different hp and the big one might not be justified... Just a thought, could definitely be wrong, I'd pick the 9760. |

Northville, SD | 9860 is considered so big that it looses that new depreciation very fast. As a used machine it is by far the best buy. I would jump on the 9860. |

NE SD | Our 9760 with the 9.0L and bullet rotor consistantly runs 1-2mph faster than the 9650w with 35' heads in beans. It will comfortably run an hour earlier and an hour later at night as long as you can cut them off. In wheat it will run the .5 - 1 mph faster with a 35' vs 30' (on 9650w) platform during the heat of the day and be reduced to about the same speed when things get tough. In corn there is no comparison. If you can find a 9860 that suits you by all means go for it, especially if you raise wheat. If you are corn and beans only I don't know that the extra cost would be worth it. |

Aurora, NC | We went from a 9600 to a 9660 in corn and I can't see the need for the hp in our situation. The 9660 was about 20% more capacity in corn. We will start beans tomorrow running beside our 9600 with Trimpe bars and both 30ft heads. We shall see. |

South-central Nebraska | I'd place my bet on the 9660 over the conventional in beans any day. |

|
NC Nebraska | I agree, it'll run circles around the 9610 |

I ram a 9650 etc for several years, then went to the 97 series because of the motor. The 96 was ok, but more limited than the 97. With the 97 you can cut with a 30-35 foot head at just about any speed, Engine is matched to just about any corn head from 8 to 12 rows.
To me, the 98 is a step child. To big and expensive for a 12 row corn head, but to small for anything else. Specs are similar to a 97 but much more expensive for a bigger motor that one really doesn't need in my opinion unless you are using a 12 chopping head, then you need the power.
Here in Central Illinois they had 15 9770's and 1 9870. |

| I bought a new machine in 2004. All machines have the same threshing and separating units. The difference was in the options and horsepower. A neighbor had a 9860 then and had problems in wheat with the air filter always plugging. He also said it liked it's fuel. However, he traded two years ago for another 9860 and this year has a new 9870. I suppose John Deere has addressed the air filter problem on the older machines by now. I would not buy a 9660...less horsepower, smaller grain tank. less options. Also I think the feederhouse gearbox is not as heavy as the others. What I did was buy a 9760 and added all the options so the only difference in mine and a 9860 is the engine and the decals. I am very happy with this machine. I would recommend a 9760. If horsepower is a problem, you can always buy a chip, which I have not. The most important advice I could give you is buy one with the 300 bushel grain tank and the high capacity unloading auger, you won't regret that. Wheat is the hardest crop to harvest with any machine. I would recommend the small wire concave for wheat. I use the standard round bar for soys and corn and they go through the machine like water. |

| If it absolutely HAS to be a John Deere and these are your ONLY three options, then I would pick the 9660 or 9760. THe 9860 is a fuel hog with that 12.5L engine and you will burn a lot more fuel just running around with it than you will the other two. Not that the 9L is that great on fuel either, but the 12.5L is awful. Unless you truly need the hp, you don't gain anything with the 9860 anyway - it is still a small combine with just extra hp - not a real class 8. |

| Is the high capacity unloading something a used combine can be readily updated to such as sprockets and chain, or is it more complicated i.e. gearboxes, etc. |

What is wrong with a 9660 if you actually looked up anything you would know you can order a 9660 equiped exactly the same as a 9760, I know because I have done it three times actually I have a 9670 now but had 2 9660 prior to this one only time everything could not be order the same was in 04' you couldn't get the HUR auger on the 96 but since 05' everything that was avaible on the 97 was also avaible on the 96 including the HUR auger/bigger grain tank, heavy duty gearbox reverser, heavy final drives and everything thing else you can put on a96 to make it just like a 97 and it still costs about 10,000 less for a 96 with all the options and I guess like you said you can always get a chip if you need more HP but like you said also have never needed it actually I had a 9660 BR and a now a 9670 and both will outperform a regular 9760 (Non BR) Dennis SEND |

| The 9660 does not come standard with the high capacity unload auger or at leas the older ones didn't. If you choose a 9660 make sure that is on there. It is well worth it in my opinion. I believe the 9760 and 9860 it comes standard on. |

NE SD | 17" unload auger vs. 14". |

NE SD | Why do you even reply to these posts? I don't think anybody here was asking for your typical negative commentary. |
|

|
| How is trying to save a guy money on fuel negative? Neither you nor I can change the fact that the 12.5L engine is a fuel pig - that's JD's problem and the man asked for reasons to steer him toward or away from a certain model. If you can't stand to hear or know bad things about JD, you better not look too hard. |

Northville, SD | This is way off the subject, and I keep hearing about the unloading auger. In light of that when someone comes with an unoading auger that will unload on either side of the combine then I can a real efficiency added to the combine. No extra power, no extra anything, just a higher price and the improvement in effiency would be outstanding. After all isn't efficiency the name of the game. |
