1460 I.H. setup help

[Haley]

Does anyone run a 1460 I.H. in corn? I have been helping a neighbor with his corn harvest and he is having trouble setting his 1460 in 18% moisture corn.I have been running my two 642's in the same field and they are running around 4 mph with 4 row corn heads in 150-170 bpa corn.He says that anything over 3.5 and it really loads his combine and rotor speed drops bad.He is also running a 4 row head.I haven't been around a rotary much but I tried to help him set it the best I could.He is running the rotor at around 700rpm,fan at 900-1000,and both sets of screen about 1/3to1/2 open.The main problem is that the cobs are split and busted out the back.It is not leaving anything on the cob and looks like a cyl/walker machine would if the concave needed to be opened more.He has opened the concave to almost the cleanout setting and still has this problem.There is a lot of cob pieces getting in the grain tank.The second problem is that it is loosing a lot of grain out the back.I know that this probably can be fixed by playing with the screens and fan speed but how much is normal for the 1460 to lose out the back?Not trying to start a color war but I always thought of a 1460 as a big capacity machine but the way this one is running right now my two old 642 Fords will eat it for lunch.I would really like to help him get it set to do the best it will do but I dont know much about red rotary combines and need all the help I can get.

Put your concave adjustment back up to the proper settings which are clearly marked near the adjuster ratchet. The cleanout setting is for cleanout,not harvesting. Then get a tape measure or rule and set the sieves according to the chart in the operator's manual. Likewise wind speed after sieves are properly adjusted. If you read the manual and adjust accordingly you shouldn't have any corn out the back.

If set correctly and the cobs are not very soft, they should come out unbroken. Rotor speed looks too fast, I run less than 400 rpm with my 1480. My 1480 does have a bigger dia rotor, so the circumference or rasp bar speed is faster for a given rotor speed. Slow the rotor speed down and close the concave to a normal setting. Many open the bottom sieve all the way and use the chaffer sieve to clean the grain but this would be tough to do if you are breaking the cobs into small pieces. However, I use both seives to clean, and use near maximum fan speed. The 1460 should "blow the doors off" those 642's in corn.

Close down the concaves and lower the rotor speed as James said.

I have run 30% corn with no problems.

I have never had the rotor faster than 550 in corn.

Also adjust the seeves to the book settings.

Sorry I cannot help with exact settings because all I do is run my B-in-law"s 1460 but I can say that there is a whole lot of something wrong with your neighbor"s or his settings. We run corn that good all day long at 3.5 with a SIX row. On flat ground 3.5 MPH with 200 BPA corn is no problem. Never a problem for power or threshing, corn overthe chaffer and out the back is what governs our speed.

1460 was the best combine ever owned.1680 next and now 2388.After minor problem after problem wish the 1460 was back.Run the rotor back to 350-400rpm and the concave back to recommended setting.Cobs are busting due to excessive rotor speed.And slow the fan speed down.We are only running 790-810 and have never been docked for foreign matter in corn.
