Case IH Harvesting

Welcome to Caseihharvesting.com!

Fall Harvest Season is upon us.  Check out these Soybean and Corn setting for Flagship combine.  If you have a Midrange combine, please visit the Crop Setting Page for Setting Information. 

Soybean

Suggested Soybean settings for Flagship

Concaves

Large wire modules for the concaves, but Round bars configuration will work good too. Can leave in the Round bar concaves set up that was used for corn, but have a Large Wire in the Right hand front Grate Area: Use Large Skip Wire in grate area. (* See note below with using the new RB)

Rotor Configuration

Recommend standard rotor rasp bar configuration. Normal AFX Rotor with 8 spike bars on rear half and 4 straight bars.

Vanes

Slow or Mid Position. Usually left in the slow position after it has been changed.. (*May also Increase
HP requiremnt)

Rotor Speed

Base line is 600 to 650 RPM Many of us usually like to take rotor speed up until I see the soybeans actually crack in the grain tank and then, back the rotor down 50 RPM’s to find the sweet spot. We then get no crackage, but can run maximum sweet spot rotor speed) This is a nice way to use for different varieties and moisture levels. Use 2nd range on rotor gear box.

Concave Clearance

Base line is 15 mm.

Pre Sieve

Louver opening should be thickness of soybean seed -3rd or 4th Notch. The long finger corn slat sieve still has a lot of opening when it is closed. We only want 15% of the grain to go through the pre sieve Chaffer Sieve: Base line setting is 14. (1 5/8″ closz/corn Sieve can be used.)

Shoe Sieve

Base line setting is 18. (1 5/8″ Closz or 1 1/8″ small grain sieve can be used.)

Fan Speed

Base line is 1000 RPM. The cleaning system fan is very efficient.

Chopper

High Speed with the stationary knives engaged.

Residue Spreaders

Adjust residue spreader speed to the higher side to try to give full head width spread. If you have 30 series and newer flagship combine, adjust the mass distributor UP (Whales Tail) so equal amount of residue is on the ground between the wheels, verses outside the wheels. Consider kit below.

Elevator Speed

Low speed, less wear and tear on drives

Harvesting Kits for FS Combines

-10/20/230 Series Combine Residue kits- Part # is 47829420 which subs to 51474747. Latest divider currently used on 240/250

  • Kit includes:
  • Divider Assembly:
  • QTY 2 Manual Adjusters
  • Screw w/ handle for fore/aft
  • adjustment
  • Hardware
  • Manual Adjust-Fits all vertical spreader options -Tool free.

The Advantage of this divider is versus the older style is that this has a wider range of adjustment for a wider even spread pattern.

# 250 Series Only Automation Tips

For the 250 Series Combines only, Harvest Command Automation quick set up below- Can be engaged while harvesting, however recommend harvesting at least 4 minutes which will automatically calibrate the sensitives.

To Begin

1. Enable Automation by pressing the top of the Automation switch. The letter “A” will display in the Icon below

2. After selecting the Automation tab, make sure the Crop type, Strategy, Max ground speed and Max engine load is set. This section is found in the Basic Tab. See pic below.

  • Suggested Strategy is Performance mode. The priority in this mode is to reduce losses.
  • Suggested Max Ground speed-depending on field conditions, 4.5 mph is a good start place.
  • Suggested Max Engine Load- 105%. This allows a cushion to recover in tough conditions.

3. Select the advanced tab

  • Suggested Initial settings set to Current Setup. This will use the current settings such as the recommended settings, when Automation is activated, therefore allowing the Automation to automate to those settings.
  • Suggested Adjust Frequency setting set to Medium. This setting will take 20 seconds before changes are made.
  • Suggested Threshing condition set to Medium. This will adjust the Cage vanes depending on rotor loss.
  • Suggested Max Rotor speed, set to crop type. Corn 420 and Soybeans 720 pm.

4. Use the Feed rate, be sure to use this mode when using the Automation. Sometimes this is called “Cruise Control” which allows the Combine to vary the ground speed automatically while optimizing the settings.

  • 1. While harvesting for at least 4 minutes under a consistent crop load and the speed you want, engage the FeedRate by pressing and holding the Feedrate button for 2 seconds. An audible beep will sound as well as an icon on the display. At this point, it is activated.
  • To increase/decrease the ground speed, press and hold the shift button located at the front of the handle, then use the -/+ feeder up/down to speed up or slow down. This will reset your target set point every time this is pushed.
  • To disengage the FeedRate when unloading, move the handle back or forward. To reengage, press the Feedrate button once, it is now activated again.

5. The Automation can be fine-tuned if need be. Use the funnels to change the sensitivities. Also, refer to the operator’s manual for further explanations of the sensitivities. Make sure to harvest at least 4 minutes to calibrate the sensitivities.

Corn

Suggested Corn settings for Flagship

RB = Round Bar

Concaves

Left hand side #1- RB. Left hand #2- RB. #1 Right hand concave- Large wire. #2 right hand concave- RB. This setup is a factory option. In High Yielding corn, ok to use a RB in #1 right side, however be aware could overload sieves on the RH side. Very Good set up for both dry and wet corn.

Grate Area

Use Large Skip Wire in grate area. (* See note at the end with using the new RB)

Rotor Configuration

Recommend standard rotor rasp bar configuration. Normal AFX Rotor with 8 spike bars on rear half with 4 straight bars used at the rear of the rotor – grate area. May use four additional straight bars for very high yielding corn.* (See below picture)*

Cage Vanes

All (9 vanes) in Slow position, front to back. Reduces rotor loss, especially important with higher yields. Also helps get kernels off the cob in tough conditions. (*May also Increase HP requiremnt)

Rotor Speed

Base line is 380 RPM. Operator’s manual suggests 350 to 400 RPM. Use 1st range for rotor gear box.

Concave Clearance

Base line is 25 mm. Can be at 18 mm with a spongy cob. The width of a cob should just fit between the rasp bar and the pinch point. This is the most critical adjustment for corn. The idea is to roll the ears through the rotor and not tumble them with too wide of a setting. Too wide of a setting will tumble the ears and cause excessive sieve load with broken cobs.

Pre Sieve

Louver opening should be thickness of a corn seed or 3/8 inch – 4th notch, perhaps 5th notch. (If you ever get grain in the cleaning fan, chances are you have the pre-sieve too wide.) We only want 10% of the grain to go through the pre sieve. Use the 1 5/8″ Closz Sieve.

Chaffer Sieve

Baselines setting is 14 mm. Close down sieve if bits of cob in sample. 1 5/8″ Closz or 1 5/8″ Corn Sieve will work.

Shoe Sieve

Base line setting is 18 mm. Keep the bottom sieve open more than the top sieve. 1 5/8″ Closz Sieve is used. The 1 1/8″ Sieve used for small grains is not recommended. This has less capacity due to hole opening. Pic below. Will have to use a wider settings if used.

Fan Speed

Base line is 1050 RPM

Chopper

Low Speed (always drop stationary knives for low speed. Never chop in in low speed.) Residue Spreaders: Adjust speed on residue spreader fans so cobs are thrown to the width of the head. If you have 30 series and newer flagship combine, adjust the mass distributor down (divider) to a wider opening so cobs can get through.

Elevator Speed

Low speed. Recommend that the Clean Grain Elevator is set to the high side on the pulleys IF harvesting higher than 4500 bu/hr consistently and moisture is above 25%. (Reason is: the clean grain auger has to turn fast enough to take away high yielding corn, so it does not build up in auger trough. Low side will have less grain damage and still do a good job under 4500 bu/hr throughput

1 1/8″ Sieve (Not Recommend for Corn)

1 5/8″ Closz Sieve

Rotor Configuration

Harvesting Kits for FS Combines

Round bar 25mm Grates

These are new this year and purpose of these grates is to have less or eliminate the hair pinning of the straw. These grates are placed in the grate section where the Large skip wire were used. Recommend that two on the left and two on the right are used. We have had good results in both Corn and especially in Soybeans where the Fungicide has been sprayed which can leave green stems. The spacing between the bars is 25mm.

Not recommended in place of the concaves.

The Kit number is 51508475.

23 degree Rasp Bar kits for High Yielding corn

The 23 degree rasp bars will slow the crop speed to provide additional separation. These bars would be placed over the Concave area only. The part # for the individual 23 degree bar is 47506580. The kit # is 48080563.
