S MN | Do any of you run a 12 row head on a Case 7240 Class 7 combine? What issues do you have? recommendations? I know the Claas Lexion class 7 combines can handle a 12 row pretty easily, but curious on the this version of Case.
Thanks |

North West IA/western AZ | My renters have one on a 7X20 Case. |

| Run an 4408 Chopping on a 7120. Based on all of the posts on here about people breaking wheel studs off red combines, I'd really question doing so. I'm sure several people do it without issue. |

|
| A 7240 has the same cleaning system and about the same power as an 8120 so a 12 row head won't be any problem. |

Cambridge, southwestern Nebraska | I know of at least 2 running a 12 row on 7240's around here. Don't believe they have any problems. |

| Friend of mine ran a 12 row on a 2388 for years so I'd sure hope a 7240 would handle it. |

Urbana, Ohio | Know of plenty in this area running 12 row corn heads on 7240s. Many are folding Geringhoff or 4412 heads.
Claas 740 will break wheel studs too, I don’t think it’s just a Case IH issue. I know from the experience of changing them on ours. Folding 12R30 Geringhoff on front of ours |

Illinois | 35 years ago when corn yields were much less...... |

|
| Deere has plenty of problems breaking studs and wheels on combine duals too. |
|

|
| Yup, yields were probably 1/2 of what they are today. JD 1243 heads are also a bit lighter than current chopping heads. I would think the target market for the first 1243 heads was the western fringe of the corn belt where yields were usually under 100 BPA. There were guys in MT that ran 30' rigid heads on 7720's where wheat yields were 0-30 bu/A. |

Illinois | Yes, I agree. I think Deere and Gleaner had the 12 row corn heads about the same time, in the very late 70's or early 80's, and sometimes people forget about how much less grain we were actually pushing through the machines then. I would think an 8820 or N7 would have a pretty full belly taking 12 rows of 225 bushel corn. |

SW MN | Should be no problem. I Run one on a class 6 |

| You could run a 12-row on a class 5 machine, if it would pick it up. Every machine is capable of so many bushels per hr. You just have to drive the correct speed to make it work. The size of the head doesn't really mean squat. It's what the harvesting/cleaning part of the machine can handle. |

Cambridge, southwestern Nebraska | You are exactly right. |

n.c.iowa | We've ran a 12 row chopping head on our 7120 for two years, no issues. The 7240 has the larger sieve area, but we've never found sieve capacity to be a issue in our 7120.
The other thing you'll have to check is your lift cylinders, I think the big lift cylinders are 80mm, I'm not sure what the 7240 came with, but our 7120 has 73mm cylinders, so we added a third cylinder kit, so we got three 73mm cylinders, as a bonus it seems to make the bean header alittle more responsive.
I should correct myself, we did have one issue, the lateral tilt cylinder broke it's Clevis top off on the last acres this past season, don't know what exactly happened there.

I would think an 8820 or N7 would have a pretty full belly taking 12 rows of 225 bushel corn.
Gleaner was the first in 78 or 79, wasnt Deere not till 81 or 82? I will admit an early black belly corn head is not quite the header a 40 series cornhead is though, both of them had frame trouble though... ;)
And a N7 will keep the tail glued down with zero ballast and no optional rams or final drives, and with 270 hp at 2100rpm and 315 bushel bin and a massive clean grain elevator they were a true 12 row machine.
JDs first true 12 row irrigated corn machine was probably the 9750 STS, and the 2012 S680 was the first JD that finally surpassed the 1979 N7 bin capacity. |

NW KS/ SC ID | A guy I help during harvest ran a 12 row Geringhoff on a 7230 and it handled it fine weight wise.
On a steep downhill slope it loaded up the grain pan and when it got back on the flat it puked it onto the shoe, overloaded it and walked alot out the back. I could visually see it do it from the graincart tractor cab, and the operator confirmed the loss meter went nuts when it happened. we were doing 3-3.5 mph in 220-240 bushel corn.
But that is more a machine flaw than anything to do with the 12 row. if we were going fast enough with an 8 to get the same bushels per hour it would have done it too.
No broken wheelbolts, but the transition cone punched through mid harvest. again, no blame on 12 row, but a machine flaw. |

| I run a 12R30 chopping head on a Deere 9770 (have the 5 speed feeder house so no worries there) handles it easily, don't set any speed records but we still do 25K per day just have to run 12 hours to do it instead of 6 or 8 hours if I had a bigger combine then I would need more trucks, and faster grain handling setup/dryer or else the combine would just be sitting at the end of the field waiting anyways. |

| We run a 12x30" on a CIH 7230 combine. 2017 was our third harvest running a 12 row corn head. No issues so far other than having to run slower than with a 8 row. But, running a slower ground speed was the reason we went with the 12 row. Corn head does a better job at 3.5- 4 mph than running the 8 row at 5.5 -6 mph, plus combine doesn't rock as bad and gives the operator a little more time to watch things. |

Ontario | A neighbor has an 8120 that left a trail of beans behind it after it came down a slight Hill that ended at the headland. You could see the trail after they had sprouted and it was quite thick. These were not even high yielding beans . |

S MN | Thanks for some great comments. |

n.c.iowa | Just because they figured out to buy or lease a combine, doesn't mean they know how to set a combine.... |
|

|
n.c.iowa | When I started out in the biz, the first machine I ran was a 715 combine, and hauled away with a couple pairs of stanhoist barge boxes, unloading with a stanhoist elevator.
Boy have things ever changed. |

Settings can only go so far to deal with a flaw.
On a slope the machine has no control over the grain that is on the pan, pure and simple.
The auger beds cracked grain and stirred chaff in with the grain, but at least they had better control of the grain.
Of course there is a combine on the market that isnt slope sensitive and has 100 percent control of the grain at all times, but what fun is that? :) |

n.c.iowa | The sieves self level in that machine,(or at least they are supposed to).
In beans you almost got to be trying to run them out the back, for that to happen.
In high yielding corn it can be a issue, but not one that can’t ge solved.

NW KS/ SC ID | dont they only level to 15 degrees side to side?
There is no way to convey grain a flat piece of metal that is facing away from its destination without some type of conveying system, so unless some type of conveyor is implemented I dont see how the flaw can be solved. Pulling way back on the hydro is the only solution with the current setup. |

Class 7 Combine with 12 row head?
