Combines Young Farmer looking For A Good Combine To Start Out With

[Jollygreen]

A John deere 7720 in good condition would be a great combine for a young farmer.

Jollygreen: Wouldn't a 7720 have too much capacity for a 6 row headIJ With a 9410 we can go nearly 5 MPH in 190+ bushel_acre corn. Keeping a combine full is the key to shelling quality in corn.

I would recomend the 6620, they are very good machines. One of your questions that I can answer is about the cab. I drove alot of JD combines and the cab in the 6620 and 7720 is a lot cleaner and has a lot more sound proofing than the 6600 and 7700. Good luck!

hey there...one thing I hear some folks say is you have to have the machine full to work right. I have run several different machines in the last 30 years, and I can't really tell much difference whether you take a half a cut or a full one so I really wouldn't lose any sleep if I bought the bigger machine. 6620 is ok, get the heavy rear axle or you will have a worthless green pile. You will always have to drain the final drive oil every couple hundred hours to check for bearing or tooth failure which these seem to be prone to. Don't get a titan II, they have speeded up the shoe and they tear themselves to pieces in an expensive way. 84 models seem to be the best of all. Tape over the inside cab air intake and you will have just as clean a cab as the 9410 you drove. This makes the cab pressurized unlike before with air intakes in and out in the same circuit. I have owned a 6620 for 15 seasons and can tell you a whole bunch of tricks to stretch life of machine. Don't get anything but a hydrostatic drive, period. A decent 6620 at a sale probably won't bring 10 grand. 7720 would be pretty good if you have level land, they are a real corn hog, but parts will be higher. Good luck!!! GS

Your in the line of the l2 or l3 if you want that size heads for conventional, or an N5, R5, or N6, R6 for rotary. If you go with the N series, make sure it is atleast a 1982(series 3) or newer. The earlier N's weren't built as heavy or as well and had way too many updates. All of these machines should be able to be bought with heads for under $25,000, the R being the most expensive. The rotaries are by far better if you plan on corn and soybeans. I now own an 82 N6 that is Hyperized and is one fantastic machine, it well out performs my uncles 2388 and the neighbors 9750STS with the same size heads. And I put a fraction of the dollars in it as they put in theirs! If you watch around too, I have seen several N's and R's with Cummins conversions.

You might want to think about a R62 with the air cooled 780 cubic inch engine, they are at least ten to fifteen thousand less than the 505 cubic inch cummins which are under powered and have a tendancy to run hot. There is just no subsistute for cubic inches when it comes to power, the air cooled has at least 25% more power than the cummins and it will produce it on less fuel. The parts for the Deutz cost more than parts for the cummins but if you are religious about keeping the engine clean you won't be buying many parts. Just remember to keep oil fuel and dirt off the cooling fins and you won't have any trouble.

You didnt mention how many acres you plan to harvest. That would be helpful in deciding which machine to get. Secondly, 36 rows are rare in these parts. Have you thought about getting something more standard like 30IJ Tom in MN

 

[99_9410]

We used to have a 6620. That should have enough capacity for you and was a great combine. And now days they are going very cheap. good luck!

blv, I'm starting out with an 8820 T2, plan to use a 925 and 843 CH. A 6 row on a 7720 will be a good match, especially in 190+ crops - an 8 row would definetly be useing all your capacity and filling up your tank fast also. I would go for a T2 - you can easliy change the sprocket that drives the shoe and slow it down. I think you could find a good 7720 T2 for under 20K. Gg PS - where are ya fromIJ

GG: From what I have heard, a 7720 is too much of a hog for a six row head and would be best suited for an eight row. We couldn't run an eight row head, as we plant with a six and twelve row. Too many curves and point rows up here in Nebraska.
