Normal Wheat Settings for Flagship 30 Series, 20 Series and 10 Series Axial Flows

Initial Normal Wheat Settings for Flagship 30 Series, 20 Series and 10 Series Axial Flows

Here are some suggested that we have used in N.A.  This will help you get a good start and you can adjust accordingly to your conditions.

Concaves:   Small Wire modules in concave area.  If Hard Thresh Wheat-See Settings below for “Hard Thresh Wheat”.  In order to get best threshing, make sure the concaves have been zero adjusted and the concave are level to the rotor front to back.
Grate Area: Use Large Skip Wire in grate area.  (Note: Large Wire or Slotted modules can be used in grate area if the straw is brittle to help prevent broken straw on sieves.)
Rotor Configuration:  Recommend standard rotor rasp bar configuration.  Normal AFX Rotor with 8 spike bars on rear half.  Note: There should be no straight Separator bars on the rotor.
Vanes: Mid Position
Rotor Speed: 750 – 1050 RPM. Use 3rd Range in rotor gearbox.  (Make sure there are no straight bars on the rotor.)
Concave Clearance:  5 mm or thickness of wheat seed.   (early model flagship combines with early software may read as a 1 to 2 setting.
Pre Sieve: Using  1 and 1/8th inch pre sieve – Louver opening should be thickness of a wheat seed or 0.4 or tighter. (If you ever get grain in the cleaning fan, chances are you have the pre-sieve too wide. )
Chaffer Sieve: Using 1 and 1/8th inch grain chaffer sieves-15 mm or about 9/16 inches.
Shoe Sieve:  Using 1 and 1/8th inch grain shoe sieves- 8 mm or about 5/16 inches.
Note: For sieve settings this year, most operators are reporting that 14 on the top and 12 on the bottom is working very well.  If you want to try a different combination, use 12 on the top sieve and 10 on the bottom sieve.
Fan Speed: 900 to 1050 RPM
Chopper:  High Speed with stationary knives engaged. (If you are going to windrow and want to set the chopper to Low Speed, be sure to drop the stationary knives all the way down. Never, Never chop in low speed. If chopper is going to be in low speed, make sure stationary knife pack is dropped down!)

The NOTES below are items also related to Wheat Settings and Performance Information:

**For operators in the Dakota’s, Montana, Canada: For best Wheat Samples, it is suggested to use the cover plates on the upper cage above the #2 modules.  It is also suggested to use the cover plate over the chopper pan grate.  Pictures and part numbers are listed below.

Other Notes for High Performance Settings:
1. Some folks can use a number 3 (20 series would be about 10 mm) setting for the concaves and then drive faster in order to add more material to thresh the grain (more material on material threshing).
2. Some folks like to put covers on the upper side of the cage over the number 2 module. This can reduce the amount of broken straw and chaff on the cleaning system. There are also covers for the upper cage over modules 3 and 4.
3. Another little trick is to put cover over the chopper grate to reduce broken stems and chaff from coming down and overloading the sieves. Any of these covers are available from Case IH dealers.
4. Make sure to check levelness of the combine front to back (Keel angle). The rear of the combine should not be anymore than 3.5 to 4 degrees Max, higher than the front. This can be checked by putting the combine on a level floor and using a angle finder on the Main frame.

Here are some Part Numbers on Hard Thresh kits, cover kits/plates:
– 87748389 This is hard thresh Rotor Kit. (It includes #1R & #1L concave modules with concave covers.) It also includes 2 upper cage covers that go in the upper cage above the #2 modules both left and right side . If you want just the Hard Thresh module. #1R is 87741400. #2L is 87741402. This is a great kit if you have hard thresh wheat. A lot of folks can get by with just the #1R module (P/N 87741400).

-Upper Cage Filler Covers over Concave Area: 87584185 is the part number for the upper Cage filler plate service kit.  (kit includes both L.H. and R.H. cage filler plates)  These plates would go above the #2 Module section.  Use these if you have whole wheat heads, or partial heads in your grain tank.  They will keep  loose brittle heads in the rotor for another 2nd and 3rd rotation in the threshing cycle.   See Picture.

– Chopper discharge Grate Cover Kit for 20 series combines and 10 series combines after HAJ202001.   Use Parts Service Kit 73340388.   This is the cover and the hardware.   (For model year 2008 and newer)

– Chopper discharge Grate Cover Kit for 10 series combine before HAJ202001: Use 84083460 Beater Discharge grate cover kit.

-Upper cage cover plates above separator area: This would be in real brittle straw conditions in which your are trying to keep broken straw off the sieves.  Cover plate kit is 84084762. (This kit includes 4 small covers and hardware.) Usually only need one kit. The best place to install plates in the upper cage is above #3R module toward front and above #4 R module toward rear. Then, same on Left side, above #3L toward front and above #4L toward the rear. Make sure they go in upper part of cage above these modules.

-Manual Adjustable Residue Deflector Kit: An adjustable deflector is available as a dealer installed kit (part number 87328003) for 20 Series combines (72/82/9230 series have this standard from factory with a chopper).  This  kit is used where you may have wet damp straw or damp soybean straw loading on the right side of the rotor and notice more residue on the right side than the left side.  It goes on the right hand side between the back of the rotor and the chopper.  The deflector is adjustable, allowing you to better direct straw through the chopper and to the spreaders.   (In order to get more even spread pattern from right to left side.)   The kit is available for machines  after serial number HAJ202001.  20 series combines equipped with the Magna cut chopper have this as standard equipment.  In normal straw moisture conditions, the residue can be managed very nicely without it.  However, for those folks that may have to  combine in extreme tough straw conditions and want the ultimate residue management spreading, see your Case IH dealer about this kit.  It’s pretty easy to put in too! (provided it is after above serial number.)
