WC MN | Had some neat features, complete shaft monitoring in its day, buttons for everything don't remember any manual engaging. Great cab also paint quality on White combines was light years better than White tractors. Grain unload system and hydrostatic drive were bullet proof, nothing else was. Final drives and rear steer spindles all failed, chopper would self destruct from roping off rotor, general bearing failures everywhere, had a taste for feeder chains. Aside from that awesome combine, biggest disappointment going to a 1680 was grain loss, it was impossible to throw corn over on a 9700 the CaseIH has to be fiddled with. An ambitious type would buy one and put bigger final drives on as well as a Mud hog, probably replace V8 Perkins, it couldn't handle hydraulic pump drive then basically upgrade all bearings to something bigger and better. In general a CaseIH combine can be gone through and run entire season without fail 9700 series needed daily close inspection and repair. |

Hanska, Minnesota | I have run a 9720 for 12 years now. They are big. 31.5" rotor ran front to back. big feeder house and cleaning system the feeder house is big and hard to plug. Drives nice and is quite. It runs out of power around 3 mph in green stemmed beans with the 30' head. I don't have any trouble with roping unless the leaves are still on the beans. Then it will rumble a little. In dry 50 bu beans I can run close to 4 mph. Runs about 3 to maybe 3.5 mph in 200 bu corn with a 12 row the limiting factor is the clean grain auger. It's easy to set and gives real nice samples. The main reliability problem I have is with it, is the sealed feed impeller shaft bearings. It's a beater shaft between the feeder house and rotor intake that knocks out the rocks. AGCO sells skf brand and I was doing good to get 100 hrs out of them. No grease in them so i found out. I rebuilt the feeder house which used the same bearings on the top shaft and have had trouble ever since with it also. I'm hoping to up date it to the newer style spiral style feeder with bigger bearings kinda like the newer MF combines have this summer. The engine is a 640 v8 perkins mine is terribly cold blooded and likes to run hot above 75F but the only repair has been a water pump. It tends to collect allot of dust on the engine and tons of chaff every where else. I blow it off all the time. It's allot of work to keep it clean. Other than that it's been pretty reliable with general off season maintenance. It's got 5500 hrs and I have no plan to retire it. The last few years i have slowly started restoring it. It's as much a collector item for me as my main combine any more.

SW Ont | MF sold a few 8590's -- basically a rebadged 9720. |

N. E. Indiana | Here is another really clean 9720. Pretty rare beast and it was a beast in its day. Had a farmer stiff the local dealer on one and that broke our oliver white dealer in town as he had to come up with the money for it.

NW KS/ SC ID | it is the grandfather of all current agco axial combines.
when someone tells you its a massey rotary, correct them. It is a White rotary. I beleive the smaller axial was in the works at white but not released yet. IIRC, this is what became the 8560 and 8570 massey. |

Thanks for the info. That's a nice looking combine you've got there. Do you have any videos on youtube of that thing running? |

| You are correct, the 9320 White was set for release when Massey took over and re-badged it as the 8560. I have a picture of the prototype running on our farm in 1983 alongside our 3 9700's. I will try to get it on here. |

| Would love to see that. These combines have such a fascinating history behind them, and as someone who takes a lot of interest in machinery history, this is one machine that has a story with several chapters. It was an enormous breakthrough for combine capacity in its day, and there was 20 years of product development work that preceded the machine's introduction in 1979. Original work was begun by Cockshutt which secured funding from the Canadian government to help subsidize some of the development costs. Work continued and escalated under the ownership of White Motor in the 60s and 70s, and the company was experimenting with some pretty advanced concepts including a rotary cleaning system. In short it was always a great design that had the misfortune of introduction in tough economic times and being under the ownership of faltering White Motor which is a saga all its own, the once giant of the trucking industry and diversified behemoth was hit very hard by the downturn of the truck market in the late 70s and when farm equipment sales slumped in the early 80s, it was a one-two punch from which they couldn't recover. |

N. E. Indiana | I have heard that White was also working on a conventionl combine at the time too. One with close to the same capacity as the 9700. Is there any truth to it? I have a good friend that used to run 2 8900's then he retired on and now has an 8570 and still runs the 8900 as a back up. |
