JOHN DEERE 7720 Turbo Combine Harvesting Wheat 

They were built to last. One of my all time favorites.

I put a lot of hours on one of those 292, 4400's

The first combine I ever operated, was made right after International Harvester was sold to Case. It was a 16 series combine produced in the later half of 1985. I’m almost positive it was made right after Case IH came to be.

Defiantly one of the all time greats.

Very nice. It’s one of my favorite combines.

Thank you Paulo

I have two videos out from Half Century so far Video 1 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Nr7cxZfdIlo.htmlsi=tYlZWbAlOiGZW0zp Video 2 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VeQ7mepJCcM.htmlsi=OR3uFqLO1fF4DhID Three more are on the way.

My dad and i bought a 7720 new in 1984. My nephew has run it also. 3 generations of our family. We use a 924 straight head and 212 pickup head. Still use it every year but on limited acres. Does a better job of cleaning grain up than newer models.

The green seeds from the weeds do get in the grain tank. At the elevator that is dockage.

Depends on the weed seed. If it's light enough it will get blown out of the back combine. If there are too many weed seeds in with the clean grain it will affect the grade the grain gets and can lower the price received by the farmer. Weed seeds can also spoil the grain if it's left in a grain bin as they are usually more wet than the grain.

For custom harvest I would guess a 220 head or maybe a 224.

If you have everything set right, will do as good a job as a brand new one.

@@jeanbrandt2624 Ok, that makes sense, but .... 1. Do things stay 'set right' with the wear and tear and would the operator know that compared to the diagnostics in the newer machines? 2. Your production rate is going to be much slower, first in cut width plus travel speed. Given that the older engines are going probably use more fuel per hour, how does that work for the economics? 3. I understand your point if you have a reasonably sized farm and just want to take off your own crops without paying someone, but for these custom cutters I don't how it could take the abuse or get the job done in a reasonable time in these 2000 acre fields. 4. There must be a valid economic reason to run these new $1 million units other than they are shiny.

@@henrivanbemmel no matter what, pays to get out of the cab and check for losses. Diagnostic equipment is only good if calibrated correctly. With grain loss monitors, one can run the combine at full capacity, but with an older machine just have to run slow enough so you know you are not losing any crop. My son runs a 10 year old combine which is “newer” than many of the combines I see. He bought it for less than half of new price, has most of the “bells and whistles” on it. He harvests about 1000 acres, and can afford to have some down time during the season. Down time , cost of repairs, and depreciation are all a big deal.

@@jeanbrandt2624 Thank you very much. I was thinking of a much older machine. For me, given the experience of the major manufacturers, i would expect that a 10 year old machine should still be effective. A number of the harvesting channels I've watched this summer are using combines that aren't new and some admit to buying them second-hand as well.

I mention in the video the bale the straw and 15ft provides a good sized straw windrow to feed the baler.

Very cool. The 8820 is a monster combine.
