Combines Mod Questions

[tbran]

Will try to answer a few of your questions. As stated many times over the R series is designed to perform very acceptable right out of the box. I would venture to say that 90% have never been modified of upgraded in any way. Most people won't touch a processor because they don't know what goes on inside there. Crop goes in the front and mysteriously appears in the grain bin. Adjustments are made to maximize the efficiency in the way of cyl speed, clearance, air, chaffer and sieve settings. Those things you find here are "on beyond Zebra" as Dr. Suess puts it. The struggle began to get wet damp crops and green stem soybeans through the rotaries as efficiently as the conventionals. Gleaner's idea was to let the customer select either the benefits of the rotary, which everyone knows about or the capacity of the conventional C62. A few of the creative engineering type here have really screwed up that marketing stragedy (sic). Rotary P3' large version will perform with the conventionals in most every condition. Extended bars, heilicals, forward bars, extention of heilicals over the lH incoming area and steep pitch heilicals are all sure fire ways to increase throughput. Usually the separator loss is not a problem in the lower yielding small grains and soybean crops. Now to your Corn problem. You may already have your setting like this but double check. Make sure the grate is level, most aren't. Drop the front two marks to max. and run the clearance at the average diameter of the ave. cob size. Make sure no filler blanks are installed. With 3_4" bars, about 275-325 RPM is where we find the most capacity. Removing the sep wires as you did is correct. Reverse bars are hard on cobs. I personally had rather attack cyl loss by removing the heilicals on the lH removable grate section just above the adjustable sep grate. Yes a high wire sep grate will help with cob breakup but as a last resort ($$). The rasp bars just sit up on two cross bars and are secured with bolts_washers through the bottom. The thought here is to tear up the shuck w_o breaking the cob. 30% corn, 8 rows at a time at 5MPH is tough on the govs. Make sure you don't have a "doggy governor" instead of a "doggy combine" a snappy engine will prevent a slowdown of everything which lowers capacity and increases loss. We have also found that a hair pulling attempt at setting a combine sometimes is due to a certain variety. Some varieties are more difficult to harvest at a higher moisture than others - thats a fact. lets see I forget where I am.... no don't add steep pitch heilicals for high moisture corn, it will only hurt I feel. This option is only for us folks who can only grow 125 bu corn and let the Good lord dry it in the field; steep pitchers are for rice, ed beans, green stems soybeans and the like. Others probably can help you out to fine tune the high moisture thing. Finally, as to the sep. grate adjustment - you probably have experimented with it and since you didn't mention it you probably have found as I have that it doesn't make much difference. If you close it very much you think someone dropped anchor however. let some of the guys work with you here as you setup and enter harvest, betcha you will get enuff ideas that some will work for you! Also keep watch as to the progress of some more stuff from the field we will post about as the season offers the opportunity for some test.

Turbo, We feel your pain that is what drove most of us to strive to do bettter.Adjust per tbran's recomendations.Then do three things ,no four things more.A. Install extended cyclinder bars(NON OPTIONAl)B. Send the injection pump into lee(NON OPTIONAl,$168 cost)C.Replace reverse bars with low or half height foward push bars.D.Strap yourself in with the seat belt(optional),this dog will now hunt!Contact HyperII at 319-698-4005 for low bars or questions.No excuses allowed.

I'll help you out on the extended bar question. The reccomendation is to extend four bars all the way across and the other four need to be extended just into the discharge with paddle the rest of the way. We have all eight just extended into the discharge and it does fine - kit is sold by AGCO and called a "performance kit". Don't know the part number right off hand. If we were to do it over, we extend four all the way and the performance kit bar_paddle for the other four.

Your right, seems like when combines cost that much one shouldn't have to make any upgrades. However, I do not think that AGCO has more trouble making a combine perform as ordered from factory than anyone else. Just look at what Kuchar has done for the 9000 series Deere, improved it dramatically; they sell tons of upgrades for those. There are many different upgrades for the red ones too, both from the short liners and Case-IH. Note too how little money and effort it is to throw in some extended cylinder bars and a couple of helicals compared to the Kuchar system. I realize that is still no excuse for AGCO to not improve their machines more quickly. Keep in mind too that it is not just combines that people upgrade to meet their own needs. Just look at all the planter modifications out there. Every farm magazine seems to have articles about how some farmer has made his ultimate planter. One guy will couple IH row units on a Deere bar with a homemade caddy pulling two spray tanks. The next one says the only way to plant in his conditions is to install Case-IH rubber on JD depth wheels, install keeton seed firmers, etc As for your results from the upgrades, Im truly surprised that you still have horsepower problems with your machine, you shouldnt! We have had great luck with the extended bars etc on our R-72. Again, horsepower should not be a restraint with only 8 row head. We do not typically harvest much high moisture corn. However, a couple years ago a gas company came through some of our farms with a new pipeline. We harvested a swath of corn through each field the width of their easement. The corn ranged from 30-40% moisture and was all 160+ bpa (dry). With our P1 R-60 (upgraded too) we could run 5.3 (2nd gear) mph at 180 cylinder rpms and never work the engine. Boost pressure gauge hardly flinched.

I had the combine at the dealer to ck. horsepower and he said it was up to speck. However he did not ck. torque rise. Can you increase torque with out increasing horseopwer and putting it out of warrantyIJ I have the Gleaner extended bars in. I forgot to say in previous post that in high moist. corn I have trouble with plugging the left side of concave with green trash. I,m sure that does not help with loss. What is the fix for thisIJ The concave is set at mid position at front and the rear is sent at 9 or 10 most of the tome. A little smaller than the cob. I have opened up the front but did not like the results when going between corn and beans. I always ck. concave and seperator grat to see that they are level. Also any adjustments I do I want them to work for 20 bushel wheat up to 140 barley with green straw. I have been changing concaves between small grain and corn and beans.

Yes, the governor response can be adjusted by lee without messing with the hp. It makes a WORlD of difference if your engine seems doggy. A lot more work can be done with no additional fuel consumption. It's the cheapest $170 you'll ever spend.

Regarding why Gleaner can't make a perfect combine for you: Everyone harvests in different conditions. Gleaner's job is to provide a combine that CAN work in as many different conditions as possible, not to provide a combine that WIll work in all these possible conditions right from the factory. All the possible configurations for different crops would be a nightmare for the factory to keep straight. And I think you will all agree that we as Gleaner operators have it far better than some of our competitive guys. Poor guys have to change those concaves!! There are certainly a few more mods that can be done to the Gleaner from the factory to make it better, but we're still light years ahead of what poor Deere is stumbling to do making that STS perform. With an 8 row head, your R62 should be able to fly through even 200 bushel corn at 6, even 7 mph! I would definitely send pump in as Hyper Harvest recommended so you know it is set correctly. Also, either you or the dealer should check the concave for level. If concave is not level and a proper wedge is not present as you move from front of concave to rear, this takes unbelievable power. So check this as well. As for rotor loss, play with the separator grate. Move in 1 number increments from 9 to 8 and then to 7 if necessary to eliminate rotor loss. NO reason to have rotor loss with adjustable separator grate in '97 and later Gleaners. Extended cylinder bars also greatly improves smoothness of material flow into discharge chute.

We just went through the pump on a Magnum 7140 similar engine to R62. It had no torgue and in fact we thought that we had Hp turned up last year and still couldn't get any torgue, Now that baby humps it and has Hp too(250). We went to R72 from 62 and the main difference in corn was when unload on go or get in steep hills. Our Case IH salesman told his boss not to waste time demo ing to us in corn that he never seen so much corn harvested. last year we lapped a 9600 every 3 rounds across an 40 acre field and it made 192 dry

Turbo, lee is cummins certifyed(pump will be resealed and engine under warranty),but engine now will have balls with a attitude.We have yet to burn 100 gal.of fuel _14hr.day.Horsepower is not an issue.Couple of things: plugging of the concave and seperator grate is a common problem in high moisture corn.We are going to borrrow an idea from Kucher to try. Kucher offers niehaus concaves to stop plugging,the main difference between conventional concaves is the rods and cross bars are the same height.We are planning on tacking short peices of old concave rods to the top of the rods inbetween the crossbars on the inward 1_3 of the concave(the part that pluggs).On your reverse bars if you do not want to purchase low bars or cannot find any worn bars, simply remove the reverse bars. Replace them with nothing,you will run many whole cobbs up to the chopper.Do not run reverse (doggey bars),they grind cobbs and sap power,material goes round and round and round.On the concave,run 7_8 inch front to back, no pinch.Neighbor just stole a doggey R72 from a cat dealer,seems a disgruntled customer who had two 72's that were horesepower limitedIJIJIJIJ,traded them on one cat. HyperII blessed the machine now the neighbors only limiting factor with the 12 row hugger is the double B header drive belt(now being upgraded to a double C).The 72's tweeter is dead.The stock 72 at the "99 farm progress show could not reach the show speed limit of 5 mph with a 12 row head.(concave and seperator grate plugged with shucks,reverse bars in,no extended bars) A properly setup machine should have very few cobbs coming over the shoe.As you can see with a few simple adjustments there is another 30% sleeping in your stock silver.Hope this helpsIJ Hyper

I have been reading these posts for quite awhile now and I have seen some complaints on here about rotor loss in corn when they use the hyper program. I can see where you are increasing the capacity but it appears by the posts that you are increasing your rotor losses in the process, it just seems to me that you are causing seperation problems when you are in corn because of the volume of grain that must get out of the cage before it is discharged. I would think that speeding up the flow is something that you wouldn't want to do in corn.
