Tips/News
- Axial flow Separating capacity feature: The Axial Flow Separating capacity is one of the largest in the industry. High capacity separating means less grain loss, and more money in the growers pocket. This is especially important for operators who grow high volume crops such as corn. One thing that a Axial Flow has is the extra separating holes in the upper part of the cage. Other manufactures do not have this. The Axial Flow can use both gravity and centrifugal force to do separation. Most other brands rely only on gravity separation. The 88 series has 156 degrees of concave wrap plus separating slots over the grate area on top of the cage. The 20 series has 180 degrees of concave wrap plus roughly twice as many separating slots over the grate area and even has separating slots over the concave area. This is a big plus in high volume crops!

-Grain Quality: One of the basic fundamentals of a Axial Flow combine is grain quality. No other brand come close! However, we would like to bring up three points when it comes to evaluating kernel damage relating to Corn. Some operators believe that when they see kernel damage in the grain tank, that it was caused by the rotor. Contrary to belief, that is not true. The axial flow rotor is very gentle on the grain and is not likely the cause kernel damage unless it is so badly set (such as concaves set too wide/or way to close, or excessive rotor speed). Here are three areas to consider when evaluating corn kernel damage: 1. Cornhead Auger setting should be considered. If the auger is set to low, the flighting can peel or cut the kernels right in half, especially in wetter moisture levels. If you are a fanatic about kernel damage, here is a recommendation about auger heights: With the newer Case IH corn heads, we have the option to adjust the auger flight off the bottom of the auger trough so as to have a layer of ears “still” left in the auger trough after the corn head comes out of the standing corn. This is so as not to allow the auger flight to slice into the ear of corn, causing crown damage as the ear is transported to the feeder housing. If the corn head is being operated in commercial size ears, the auger could be as much as 2.25″ to 2.5″ of the bottom of the auger trough. Whereas, with popcorn, the auger might be 1.75″ to 2″ off the bottom of the auger trough. 2. Watch excessive tailing levels. As you know, anything that goes through the tailings will get threshed again, and perhaps add to kernel damage. As a rule of thumb, you should not see more than a 1/3 of a auger of tailings. If you have more than this, make a sieve/fan adjustment to keep tailing low. 3. Check the clean grain elevator chain. If the chain becomes too loose, the rubber paddles will bend over more, and any kernels trapped between the elevator housing and a loose paddle may encounter damage. Watch and control the above items and you will have the best grain quality around!
-Soybean Productivity tip: For really hard thresh soybeans (tough green small pods), some folks like to use a small wire concave. With Midrange combines, use a small wire concave in the #1 position with the other two concaves being large wires. In Flagship combines, some folks will use a small wire concave in #1R position and the rest large wires. This is a good little tip for those really hard thresh situations. Also, be sure your concaves are zeroed and level to the rotor. The physics need to be right.
-Manual Adjustable Residue Deflector Kit: An adjustable deflector is available as a dealer installed kit (part number 87328003) for 20 Series combines. 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.)
-Pre-Sieve or Front Sieve Section Adjustment: The 10 and 20 series combines have a pre-sieve, and the 88 series (along with legacy combines-1600/2100/2300/2500) have a independent front section on the top sieve. We sometimes, also, refer to this as the pre-sieve. Here is a good rule of thumb for adjustment: The front section or pre-sieve should be open half the distance of what the main chaffer sieve is. Some folks will say that the pre-sieve louvers should be open to the thickness of the seed you are harvesting. Anyway, if you ever experience grain in the fan area, the root cause is that the pre sieve or front section is too far open. That is the general recommendation when the grain is fit. However, the beauty of the adjustable pre-sieve is that when the grain is very wet, you can open it more. For example-wet corn wants to flow over itself -that might be a condition to open the pre sieve a bit more than suggested above. There is a lot of sieves in a Axial Flow. Think about getting 15% of the grain through the pre-sieve, and use the long main sieves for the rest. You will then get along great, and have a super sample!
-88 Series Combine and Pro 600 training Tutorials and “A” Post Training: There is a website that has a series of tutorial videos where you can learn on how to use the Pro600 in a 5088, 6088, or 7088. You can learn on header setup, combine setup, distance calibration, moisture sensor calibration, and yield sensor calibration. The Website is part of the Case IH AFS site. Here is the website: http://www.caseihafs.com/tutorials.php When it come to leaning how to use the new “A post”, there is a training video DVD. It is DVD10919. It is available through your Case IH dealer. This training video will show your operators all the functionality of the new “A Post”.
-20 Series Pro 600 training and RH Controls Training: There is also a training video for this. It is DVD10900 (also available through your Case IH dealer). This training video shows how to use all the screens on a Pro 600 and how to use all the switches in the right hand console. Do your new Flagship combine operators a favor and get them this training video!
Impellor Blades/Transition Cone: Did you know? The impellor blades on the front of the rotor (transition cone) draw upwards of 1100 cubic feet of air per minute through the Axial Flow combine! That means the dust goes through the machine and does not hang in a cloud in front of the operator which limits visibility and frequent window cleaning. Axial Flow is the only combine to have this feature! The extra air flow also aids in helping kernels separate out through the cage and module openings. Of course the main job of the transition/impellor area is to gently bring crop up to speed for the rotor to thresh and separate (which greatly reduces grain damage).
-Engine Speed Alarm on 10 and 20 series: Some of the folks are in real good high yielding wheat right now. If your engine alarm is coming on more often than you what, one of the things you can do is reset the setting for engine speed alarm. As long as you have a good ear for your machine, you can try resetting it down to 1950 rpm setting. (factory setting is 2050 rpm alarm setting.) Of course, we do not want to slug the machine, so that is why we say, you should have a good ear for your machine. The engines will pull pretty good! The max you can set the engine speed alarm down to is 1900. To Set: Go to “Toolbox”, than “Engine tab”, then scroll down to “engine low speed alarm” setting and put in your new number (such as 1950).

-Know your Physics: This is pretty basic information, but it doesn’t hurt to double checked combines before the season. Make sure the concave is level to the rotor. In other words, the concave need to be parallel to the rotor. Also, make sure the concaves are “zero” adjusted. If you have these basic physics right, you will avoid a lot of threshing issues. See your operators manual if you need instructions on how to do it. You will have enhanced performance as the Axial Flow was designed for.
-Know your Angles: As we start to get ready for the harvest season, here are a few Angles that you should know for best performance. We usually like to see a positive Keel Angle (back of combine higher than the front of the combine). The back can be higher, but should not be higher than 3.5 to 4 degrees. (1 to 3 degrees in nice.) Measure on the main frame of the combine. Head Angles: 1020 head should have a 10 degree forward angle. Measure this on the vertical back of the head when it is in cutting position. On a 2020 head, it is 17 degrees forward angle in cutting position. As for corn heads, when the head is in cutting position, the angle should be 23 degrees measured on the deck plates. These angles don’t have to be exact, but should be in the neighborhood to give the best performance and the least amount of head lost. As for the 2162 draper heads, they have a adjustable hyd. center link cylinder to adjust angle from the cab (on-the-go) for best performance.

-De-Slug Operation-Flagship: Do you know how to use the De-slug feature in a 20 series combine? It is pretty simple: 1. Move separator switch to rearward position (let go and it will go back to neutral). 2. Then, Move the separator switch to the forward position. (you will notice that everything is running on the combine except the rotor. The chopper is running, the sieves and the fan are running). 3. Run engine at full throttle. 4. Use the rotor speed rocker switch. “minus“ will back the rotor up and “plus” will turn the rotor forward/normal direction. You can rock the rotor. We usually say to back the rotor up just a little bit and the run it forward + . Repeat as necessary to de-slug the rotor. You may lower the concave slightly, but not too much minus. Try a little reverse and then forward moving the slug to the rear. We Want the Slug to go out the back of the machine! Remember, that you can shift the rotor gear box to 1st gear for the most rotor rocking power! Go out and try this on your machine in the yard ahead of time and learn how to do it. Case IH is the only company to have this feature! Can you imagine the value? If a operator slugs the machine, one can de-slug a flagship combine in short order. Time is money- imagine not backing up your whole operation (truck, drying, tillage, ect) for the day! In a 20 series Axial Flow, you can be cool and stay cool!
-88 Series Left hand access panel: Have you look at the left hand door on a new 88 series lately? The rear left hand rotor access panel is now real easy to take off. It has been formed with the bottom lip above the shaker arm. You no longer have to play with it to get off due to shaker arm contact. (March 2010)
-Combine and yield Monitor Tutorials for 2500 and the new 88 series combines: There is a website that has a series of tutorial videos where you learn (or your operator) on how to use the Pro600 in a 5088, 6088, or 7088. You can learn on header setup, combine setup, distance calibration, moisture sensor calibration, and yield sensor calibration. The Website is part of the Case IH AFS site. Here is the Website: http://www.caseihafs.com/tutorials.php Check it out! These are some nice training videos. (on another note, if you would like videos on how to use the controls and pro600 in a 10 or 20 series combine, see your Case IH dealer and request Training video “DVD10900″. This dvd has all the training videos for the flagship Case IH combines.)
-Know your Tires: Looking for tire information and specs? Here are a couple of websites on which you can put in the tires size and get a lot of information about a particular tire. The one for firestone is: http://www.firestoneag.com/search.asp (Go to the Tire Finder section of the web page.) The one for Titan/Goodyear is: http://www.titanstore.com/search/ (Try the advance search on this web page) Check it out!
-Power Plug on 20 Series combine: Do you want to have “keyed” 12 volt power for a radio, TV, or whatever? There is a power outlet on the left side of the keyswitch console that is available for auxiliary accessories. This port is rated up to 8 amps. The part number of the male connector for this port is 86508819. Also, There is a cigarette lighter plug to the right side of the key switch console, and another cigarette plug between the seat and the instructional seat. (on 88 series, there is a cigarette plug next to the transmission shift range handle. Also, there is a lighter and ash tray accessory kit P/N-434227A – field installed. It goes between the seat and the instructional seat.)
-Unload Lengths from Center Line of Combine: The unload lengths for 2010 Case Ih Combines will now be measured from the centerline of the combine to the inner edge of the discharge spout. Also listed is chart that shows the different lengths available.
-RowGuide: The new RowGuide for cornheads is now available to order. Please see your Case IH dealer if you are interested in this neat option. The kits will then ship in the summer months. The AFS RowGuide will be available to be installed on the new 88 series, and on model year 2006 and newer 10/20 series combines. The combine must already have AccuGuide on it. A pair of AFS RowGuide sensors, mounted on corn head dividers, follow a corn row and generate guidance input. The AccuGuide system uses this input to keep the combine on-row. The AccuGuide system helps maintain accurate automated guidance through areas of planter skip and across waterways. Lands can be laid out, and it will stay on path if a row is missing, as long as there was a previous path to follow. AFS RowGuide keeps the header aligned with the crop even on tight contours and curves. It’s especially helpful in staying on-row in down and tangled corn.
-Tier 4 Engines: You probably have been starting to read articles on the new tier 4 engine standards that will be required to reduce particulate matter and nitrous oxides. On combines, the current plan is to introduce the tier 4 engines for 2012 model year combines.
-Class Size of combines: Some folks have asked what determines the class size of a combine. Believe it or not, it has nothing to do with productivity levels. The one and only thing that determines what class a combine falls into is the horsepower rating. The Ag Equipment Manufacturers association has designated the following class sizes: Class 5 combines are 215 to 267 HP. Class 6 combines are 268 to 322 HP. Class 7 combines are 323 to 374 HP. Class 8 is said to be anything over 375 HP. However, Since the AEM has not officially designated a power range for Class 9 machines, CNH designates it as a combine having over 450+ horsepower.
Hopper Capacities: Please be aware that the combines still have the same hopper capacities as listed in 2009. It does not matter if combine has standard or folding grain tank covers.
5088 has 250 bu. capacity
6088 and 7088 have 300 bu. capacity
7120 has 315 bu. capacity
8120 and 9120 has 350 bu. capacity
Unloading auger extensions: Here are the part numbers for the new 52 inch extensions released for 2010 combines.
If you would the 52 inch extension part number, they are:
P/N: 84261030 – for 52 inch Extended Wear
P/N: 84262399 – 52 inch Standard wear.

-Sieves for General Purpose Machines: For areas with Corn, Soybeans and Wheat, If you would like the 7120, 8120 & 9120 to come with 1 1/8” pre-sieve with a 1 5/8” cloz slat top sieve, you can order code 425116 in the upper sieve area of the price book. There is no charge for this option. (Normally, you would order 1 1/8 pre sieve and 1 1/8 upper sieve for just wheat, or 1 5/8 pre sieve and 1 5/8 corn slat upper sieve for corn/soybeans.)
-Full length slats for 10 Series Combines: Just for information, if you have someone that would like full length slates to tie all four feeder chains together, here are the part numbers. (part number 87546907) for the feeder chains. A complete feeder chain assembly that includes the full length slats is also available.
• Rock trap equipped – Part number 87625520
• Non-rock trap equipped – Part number 87625521
-Air Compressor option: Don’t forget that there is a air compressor option on the 2010 models. The system has the following specifications:
•8.3 bar (120 psi) regulated pressure
•60 L (16 gal) tank
•198 lpm (7 cfm) @ 1000 rpm / 396 lpm (14 cfm) @ 2000 rpm
•Self coiling air hose –6 m (20 ft) usable length
•An air nozzle will be provided to utilize with the self coiling air hose and the various outlets.
- 2020 Platforms: Effective with PIN Y9ZL52001 the 3rd stripper (which was available as a field installed attachment) is standard equipment on all 2020 and 2010 platforms. The stripper keeps the crop ahead of the auger and helps with some of the bunching and material coming around the auger before it gets to the feeder we were seeing in certain conditions with these platforms.
-Beacons: When you order a 88 Series combines, you will notice that Beacons are now standard equipment. (This includes the second bin level sensor with two rotating beacons.) You can deduct this out if you do not want.
-AFS Desktop Software: This has also become standard equipment. You can deduct for it if you like. We encourage customers to enrolled in the desktop software support and maintenance program. For a small yearly fee, customer get free software support plus free software upgrades and do not need to buy the expensive software when there is a update. The current desktop software is version 10.0. http://www.caseihafs.com/desktop-software.php
-Other 88 Series Items: A lot of other items are now considered standard equipment such as Radio, Antenna mount, under panel service lights, Auto Crop Settings, Engine block heater, and other common items. They can be deducted, if so desired.
-Cold weather starting tip: On the 20 series combines – activate the grid heater by turning the key to the on position. If the cold start pre-heater is active, a tone will sound when the key is turned on. The tone will change pitch when pre-heater has reached working temperature. Wait for the pitch change before attempting to start the engine. Repeat if needed. On 88 Series combines – Turn the key to the on position. You will see a grid heater lamp on the “A” post. It will be “on” in the lower left hand corner of all the lamp indicators. Wait for it to go out and then start. Repeat if needed. DO NOT USE ETHER!
