would a 7120 be able to handle a 16 row 30, 110-180 bu dryland 15-20% i know its a 12 row machine but i am on 16 and plan to upgrade after harvest to a larger machine.i know ground speed will be slow but my 8 row i would be running approx 6.5 + i can do i better job with header losses going slow and lots easier on the cart driver keeping beside me.the 16 row lift kit is the same for a 71-81-91 .that makes me feel better about lifting it. i am wondering about sieve losses not rotor .

2500 to 2800 BPH is what the 7120 will do with no loss. 180 bus. corn,3mph 16 row 30" is 2160BPH

Re: 7120 16 ROW??

I always figure in a case like this, if you are gonna double the head size then you'll have to cut the speed in half. If you ran 6.5 with an 8 row and that was full capacity then 3.25mph with a 16 row in the same harvesting conditions will cover the same ground and should keep the machine at the same capacity level. I'll bet at the end of the day you'll like driving 3-4 mph with a 16 row over an 8 row at 6-7mph. Plus you'll cover more ground-think of this- you'll make one half the amount of turns on the headland after you switch to the 16 row.

Re: 7120 16 ROW??

YEA i think i would like the slower speed,i dont like crossing the ditches and furrows going that fast (with 8 row) i always had to slow down but if i am alreadly slow just makes sense to me and i never thought about how many rounds to do the same work i should gain just by more time on the row, now if my corn was 250 that would be a whole different ballgame,

Re: 7120 16 ROW??

not trying to be negitive but a freind of ours went with 16 row and is not real happy. depending on feild size a 16 row can be clumsy to get around with if you have big fields probably not a big deal if you have very many small ones can be a pain. he is going back to a twelve row head for these reasons. we run case ih machines and love them but even in low yeilding corn i wold think that a 16 row on a 7120 would be a handfull and really 140-180 bushel is not really low yeilds. i wish you the best of luck but i know on our 8010 i would not want to have a 16 row head on that. what kind of head are you going with geringhoff or case ih? good luck and let us know how this turns out hope you have a safe harvest season

7120 will do a 16 row with the heavy lift feeder and the 8120 drivetrain upgrade (final drives).

If your going to a new machine why would you not just go to the 8120. By the time you put the heavier finals on the 7120 wouldn't the price difference be minimal. The 8120 has 10,075 sq in cleaning area compared to the 8,370 on the 7120.

Just a thought but you may hurt your trade-in value of your 7120 some by running a 16 row head on it.

Re: 7120 16 ROW??

I'm wondering how you are gonna keep the back tires on the ground? The 8010 gets very light on the back with the 16 row and if it stops very quick the tires will come right off.(What I've read, not seen) You'll be needing some serious weights back there.

Re: 7120 16 ROW??

use wheel weights/ fluid, theres very little difference on ballasting on a 7120 /8120 ,i looked a the dealer book.
