ontario | I asked about the 1460.. it wasn't very good. found a 7720 deere with 220 flex head new rasp bars hydro static. Coming from a gleaner F2.. so no experience with anything else. how fast do they go on thew road? need to drive it pretty far if I bought it. What engine 466 I assume? Is the 220 header decent? I don't have many acres at all right now. just under 100 but will be expanding. |

NC Iowa | It will travel better on the road with a head on it, but a 220 head means you will spend a lot of time on the shoulder. I would trailer the head.
I roaded a 7700 (without head) about 70 miles and didn't do too bad. Be sure tires are up as finals have oil. Have a buddy follow you with the head, for safety of help if you need.
Get some of those magnetic trailer lights for the back of the head trailer.

Corydon, IA | Our 7720 has the 30.5 tires on it and goes about 15.8 according to the ground speed readout. It seems pretty slow sometimes. Yes, it should be a 466 engine. What to look for depends a lot on amount of hours machine has on it. I could tell you a lot of stuff to look for if its higher houred like ours.

keep looking for a red one
Even a MF a 760 would do way better in wheat
a 220 head not worth much
looks at the auger edeg needs to be sharp
a 920 is only $2000 $ 3 with a air bar |

I have owned a 1983 7720 for 29 years and mine has 24.5's on it. Mine does run the same at 15.8 but it didn't even run that fast for years after I bought it. It would only run about 11.5. Man talk about forever to get to the field!!!!! What happened was the wrong ball and socket was installed on the hydro control valve from the factory. Mine was not the only one that had that problem so if it runs really slow in road gear, that would be the first thing to look at. If I remember right, the ball and socket was too long and would not let the valve arm at full open. I replaced it with the right one and it felt like I was off to the races after that!

north east ohio in the snow belt Ashtabula co | Nothing you buy will be as easy to work on as that F2. What about a R 52. IT will also be lighter then those other 2 you are looking at.
That's all i got to say about that. |
|

|
ontario | It shows 3800 hours. Header would be on a cart for sure.. Supposed to be field ready. Yes the F2 is a great machine power auger 4 cylinder good on fuel easy to fix.. I will probably keep the gleaner too.

North West IA/western AZ | Keep looking for a red xx60 and you won't be wrong. They are much easier to work on and set than the 7720. |
|
| |
|
Northeast Missouri | I owned a 7720 and it was a very good machine. They are not hard to set at all. A properly set 7720 will do an excellent job of saving the crop and cleaning it. Given the hours, the one you are looking at has either just had a lot of money spent on it or is about ready to have. The one I had years ago had 3400 hours on it but had many new parts and was a good machine. Some combines with fewer hours aren't as good. It all depends on how they were maintained. |

SW Ohio | Our 7720 is on its 35th year around 5750 hrs. We have replaced about half to two thirds of the internal moving parts in that time and maybe a dozen other wear items, if you keep up with it, the pain is not too bad. yours could need all that right now or just some of it. Road speed could be of two choices, the final drives came in two different ratios so it might be 15 mph or 19. There may be better choices out there if you are not familiar with working on a Deere walker machine, because you will work on it. |

Bothwell ont | keep looking just the thoughts of working on a deere 20 series make me crindge |

Coles County, Illinois | I have a 1981 6620 with 3500 hours that I bought off my Dad over 20 years ago. He bought it new so I've maintained it since it was new. I'm not trying to talk you out of buying a combine, but the truth is that combines are bent on self destruction. Unlike tractors that might run 4000 hours with only oil changes, you'd better look a combine over pretty closely every 50 hours. If you let something like a leaking valve cover gasket go or chaff build up on bearings you might as well break out the hot dogs and have a wiener roast.
The flip side of this is 20 series Deere parts are readily available from aftermarket sources. I wouldn't call them cheap but many are of higher quality than what Deere assembled the machine with. At 3800 hours many of the wear items will have been replaced many times. I've lost count of how many loading augers and clean grain augers I've installed. I would have expected that your 7720 should have had the vertical unloading auger replaced 1000 hours ago, It may be ready for the long unloading auger. A troublesome repair would be the troughs in the grain tank. They do make a liner now but if the machine was cleaned out after use and stored inside then the troughs should still be OK. |

ontario | ok I understand what you mean about older combines .. learning that with my gleaner F2. Seems like combines are always needing something or broke down.. they are a necessary evil to me. I believe it has been kept inside. but will have to inspect it. I am still under 100 acres total so I wouldn't be wearing stuff out as quick but I'm hoping to really start expanding in the next few years when land rental opportunities arise. I could get by with something smaller for sure but I would much rather have the crop harvested in a few days and have less worries.
I will still take a look at it, check out chains and augers etc.. run the separator for a while and header. Any issues that they are know for?
There is also a massey 860 a lot closer with a 20 foot flex.. half the price of the deere but don't hear much good on the masseys

SE MN & NE IA | We went from a 850 Massey to a 7720 Deere. No comparison in capacity or power. 7720 was a much better machine all the way around. The Massey will have metric bearings on it. Very hard to work on ours. We broke the grain pan and shaker shoe shaft at a little over 2000 hours. A very time consuming expensive repair. 7720 with yearly maintenance was a very trouble free combine for us for 15+ years. |

Marion,ks | We had them all a new 6620,7720 and 8820T2 still run the 1988 8820s one with 3200hrs and other with 5000. at 3200hrs a lot of things will have been replaced once . or even twice. We do our repair work on ours and they have been very dependable during harvest. It all depends how well it has been maintained a 220 header is okay you can up grade to a 900 series biggest change is a extra stripper bar under the augar. We like our 8820s and plan on keep using them really simple compared to the new computer combines with there codes and sensor issues . |

X2. I owned a 6620 for many moons. Kinda hard to work on some parts of it, but those XX20 machines do a nice job if up to snuff. |

We had some issues with ours after we bought it too. The bushings and the plate were shot down where the linkage pivots from the cable to the hydro lever and it was the same thing. Snails pace down the road. |

Yep, same here also and when I replaced the bushings and the plate it did help but nothing like it did when I replaced the ball and socket. And since I replaced the ball and socket, the bushing and the plate have had no wear.

ontario | K gleaner sold.. And wasn't high enough to reach the wagon. Found an F2 that is more in my price range, long walker hydraulic auger but a gas engine. While a Lexion would be nice I cannot afford that and it wouldn't fit in some of my fields haha. I passed on the Deere 7720 for now a bit more then I have to spend anyways. |
