6620 or Gleaner F

I have been running a Gleaner F for a few yrs now and have it somewhat figured out. The problem is my floating cutter bar head is shot. Ran into a combine that has been taken care of. JD 6620. It has been hit in the rear buy a pickup truck and needs some work. Comes with a 216 flex head. Scrap price. Need some advice. Is a 6620 a pain to work on? What does a guy want to really look at? Gleaner F or Jd 6620?
 
The Gleaner is a lot easier to work on, but much smaller capacity, fewer features than the 6620. Any flex head does a much better job than an FCB. What kind of damage from the rear-ending to the 6620? Twisted components can be hard to deal with....drives, belts, etc. Must be major damage to warrant scrapping.
 
Keep the f I would not get the 6620 . I ran a 6620 and it is two heavy in front and was always working on it .plus motor needs two be on the back to hold back down on the ground in hills.
 
They are hard to work on. But if it was given proper care and maintenance they will be a very reliable combine. The JD 20 series were the best combines we ever owned.
 
You can change all the belts on your F in about an hour- may take all day with the deere. The 6620 will have twice the capacity of your F, open concaves, larger tank, better cab, much better header control, much easier to operate if its a hydrostat trans., easier to get parts. If your F is a short back, the Deere will do a better job in small grains. F series was one of the best combines made by Gleaner- simple, reliable, handy to work on. Apples tp oranges here...Ben
 
Just move up to the 7720 and don't look back you can buy them for about the same money. On all of them ask about the main bearing being greased. It is right under the seat. Most guys don't even know it has a grease fitting let alone grease it. When that goes out it is an expensive deal. If it has been changed find out when. If it was did they change the drive plate in the flywheel. That bearing and plate is the most expensive job on the whole combine.
 
If you want something that needs a day at least to fix the most simple issues you will buy the 6620. I love the fact that we sell all 20 series combines to the Mexicans at our dealer because it means I don't have to fight changing countershaft bearings on one more combine. I am a Gleaner guy through and through. I would get a different head for your F and stick with what works and is easy to work on. Plus the engine up front is a terrible idea. Let the salvage yard buy that 6620 and save your self the headache. Just my 2 cents.

Buying a different head for a Gleaner F should not be that hard as the number of them made, I see them for sale all the time. As for working on them well to tell you the truth I would rather work on the Gleaner when the Deere hands down. Changing that rear hood sounds easy till you do one and you find out how big of a pain it is. I changed one on a JD 95 once, All day job for 4 guys and my 10 yr old to start the nuts under the hood. Not so heavy just big and ockward to work with.

You need to ask yourself some questions, 1 How much to replace the F's head? (Its easy to change the head) 2 Are you ready to replace the hood, walkers and auger support and or everything on the tail end? 3 How many man hours and men will it take to fix it? It will not be a one man job. The insurance company totaled it for a reason, The cost of fixing it, Doing it yourself will cut costs but you still have to find replacement parts and transport them. How do you haul the rear hood for a 6620?

If you are like me, I don't mind working on stuff but I don't look for new projects as I have enough to last for the next couple years now. I know it sounds cheep for a big machine but is it really worth the time and work to fix it? Bandit
 
Well I thought hard about it and I think I'm going to run the F. Thanks for all your inputs. Everyone has been real helpful on this site! Thanks
 
Neighbors stopped by asking if I'd custom cut their beans next year with my F2 because it/I cut so much better than the 20year newer combine that ran their ground this year. I lol'd, and then they said they were serious.
 
We run Deere now but the gleaners do tend to clean the grain a lot better. For corn I like Deere but the gleaner better on beans. It's really all about what you prefer and what you are most comfortable working on
