This wet corn has really brought out the weaknesses in equipment this year. My old JD 7720 has been put to the test. With only 25 acres left the feeder house chain broken into a hundred pieces. I latched onto a 7700 with plenty of good pieces that I can use plenty of parts from. After looking it over more I found that it only took a few minutes to make it usable to finish the last few acres instead of taking the time to change out the chain. The old girl runs so good I wonder if I should part it out or just park for those emergencies. It won't work well with our grain carts and I really don't like the old step style. Any body out there have thoughts on tearing it down. Has a great Turbo engine and even RWA.

You could try reselling for what you have in it, or maybe make a couple bucks. Otherwise, parting it is a better alternative to scrapping it. I got a Gleaner M2 I'm parting due to mice tearing up the wiring. Do many parts transfer between the 7700 and 7720?
If its as good as you say,the LAST thing I would do is "tear it down".Sell it as a user.Better just keep it as a spare.The 7720 may break again(probably will).You will be damn glad for a 'backup'.I know I would.....A friend had a not serious issue with his 4400.In 2 hrs time his 55 was in the field and finished his crop before the ordered parts arrived.... keep it.

Will the step from the 7720 swap onto the 7700? Maybe it is possible to modify, or swap some other parts, and make the 7700 more compatible with your grain carts?

What did the feeder chain parts do to the cylinder? Ouch....

My Dad had all IHC combines. Kept every one and used parts off of them for years. The question is what does the parking spot cost? I only had two weeks to clean everything up when the farm was sold, so the rest of this story is not good. There were eight combines.
I agree the only thing that the 7720 has is more power and grain tank capacity. Many dealers tried to sell 6620"s as having equal capacity to a 7700. The threshing and separating components are interchangable in
The 7700 serries except the titan ll which is a far more capacity mAchine.

I knew some farmers that every year they would rebuild their combines and other equipment and they never had any break downs in the field.
They spent maybe some money that they didn't have too, but they always got through a harvest with out any breakdowns.
I know that sometimes the unexpected happens.

The worst thing you can do to a combine is just leave it sit, even if it's in a shed. Run it a few hours every year if you do keep it. Otherwise, it's only good for parts. Jim
I bought a Cockshutt SP combine after harvest real cheap to use as a parts machine for our Cockshutt SP. After I got it home, I inspected it an found it to be in better condition than the one that we had, except it had sat outside and had a coat of rust.
I tuned it up and we ran both machines for several years afterwards.

I've done that twice. We bought a super 92 parts combine for ours. Turned out better than ours so we parked ours. Sucked because the enging only had one season on it.
I bought an $800 Farmall M for parts for mine. Turned out better than mine so I put the loader on it. Gets used most every day. My original one is back in the corner of the shed waiting to give up all of its parts.
I agree with the guy that said use it every year. If you are keeping it for a backup run 50 acres of wheat through it every year to keep it limber.

Find a cheap old school bus, take out about half of the seats, use it to store all of the parts when you take the parts machine apart. We did that with an 8820 and used the parts for years.

I will add that if you take apart a used up piece of junk, you won't have very good parts to use later. This one was just rebuilt at a dealer's shop and then had an engine fire. New parts from one end to the other!
It's just like taking apart a pickup for parts....who wants to buy rusted out dented fenders or a box? Part out a nicer one and all of the parts are worth money.

We have a 4400 and it was getting where we were constantly patching holes. My Brother ran across a 4420 at auction that was an ether cranker and bought it cheap. It had more hours but was not rusty. For a couple of years we had corn header on 4400 and bean header on 4420. One day we were a couple of hours from finishing our beans and I hopped on machine to ride a couple rounds as my brother was operating. It had been performing flawlessly all day when I noticed that the motor had never sounded better but thought to myself if I say that it might jinks it. Two seconds later he hits the clutch and throttles back and says the engine started slowing down. We eased it back to the truck and unloaded it and were backing away from the header when it locked up. The 4400 became the parts machine as we swapped engines after we finished the beans.

The 20 series straw walkers are 20" longer then the 00 series. The only difference between the 20 series and Titan II 20 series in the separator is the shoe is 6" longer and shakes faster. There can't be a huge difference between a 20 series and a Titan II series. In fact I know there isn't because we owned 3 different 8820s with one of them being a Titan II.
