Combines gorden bar problem

[M__Gorden]

How many years have you run this 2366 that you have just put the Gorden bars inIJ How many hours are on the 2366IJ Which model corn head are you runningIJ Which part of the world are you locatedIJ When you say dockage is 1.2 to 1.9%, what does the dockage consist ofIJ Is the dockage test taken straight off the combineIJ Do you have any modifications to the combine other than Gorden barsIJ Do you run a bin extensionIJ Have you recently installed a new feeder chainIJ What are you running for chaffer and sieveIJ Where is your chaffer and sieve setIJ What fan speed do you runIJ How are your yields this year compare to other yearsIJ Are you having rotor lossIJ

Mr. gordon i am from ontario.Every thing is stock on the machine. There is no rotor loss. There is 2169eng.hrs as of today,1998rotorhrs.The corn yeild is above agerage for ower area this year and the mosture is around 19%.there is no bin ext.The dockage is cracked corn and red dog.This combine is my third fall with.This is my fifth red machine i have bought.The feeder chain was changed before this season got startedit is the flat model.There was 120hrs on the chain before i did beans with the bars.Also add the cobs are not broken at all which is very nice.The dockage is straight form the machine .The fan is runing at 1000rpm,the sieves are set n4 ontop and n3 bottom. Thank you for your help!! Rodney

How many Gorden bars did you installIJ Which corn head are you usingIJ Is the cracked corn from the tips of the kernelsIJ Most fines come from the tips which has a lot to do with the variety and how hard it is to shell off the cob. The fact that you are getting whole cobs out the back is a good indication that the bars are gentle on the corn. One of the most common complaints I hear about the stock specialty rotor, in corn, is rotor loss. For corn, Case-IH has recommended installing straight bars in the rear. In recent years straight bars are being used in the front to reduce rotor losses. Why you are getting more fines now, compared to before, considering the fact that you have little or no rotor loss, is likely due to better separation from the Gorden bars. In otherwords before the installation of Gorden bars, more fines were carried out the back with the husks. Most operators are using more air than you are (fan speeds up to 1200 rpm) with the o.e.m. sieves. The higher air settings will blow more fines out the back. Over the years, many operators have commented how well the Gorden bars work in food grade and seed crops compared to the stock bars. They work very well in popcorn which is subjected to iodine testing for cracks. Have you finished harvestingIJ

I an useing a 2000 1063 with plastic nose cones.We still have 22acres to do of corn and 220acres of blackturtle beans if we don't get to much snow tomorrow.I have only combined bt corn this fall which i never have done before.Nk 2555bt is what i grew my self.I have 9 gorden bars in the combine.I have six straight bars on the rotor. Going to try the fan at 1200rpm to see if i get a cleaner sample.Could the problem be from perforated screens on the clean grain elevator or auger. Thanks for the help!! Rodney

I would try running the shoe sieve fully open if you have full cobs out the back there is no need to run the bottom sieve so tight. I run my lower sieve full open in all crops and have never had dockage over .8% in any crop.I only run the perforated elevator bottoms in weedy food grade beans. Any other questions feel free to e-mail for a phone number. Brian

Exactly why you have more fines this year, compared to last year, I can not tell you. likely it has more to do with variety and growing conditions than anything else. Perforated screens are not something I would use. They are likely to damage the grain. Getting less fines, apart from a variety change, gets complicated. Cracking of grain starts at the header and can occur at most points along the way to the discharge auger. Sharp edges on the impeller wear plates and on the leading edges of chrome plated bars add to the problem. Rock traps can crack grain. Grain in the return system, caused by overloading the sieves for lack of air, gets cracked on the way back to the rotor. Too much air can blow grain into the return system when the lower sieve is too tight. Sharp edges on the incline auger to the grain tank can make fines. For other reasons, I suggest you add six more Gorden bars to your rotor. 15 total is the best setup for your area.

I have found the solution to my problems.1 variety is the first.The so called cracked corn is the tip of the kernel with the same test weight.2 Removed all peforated screens.3 Found the peforated screen in the unloading which I never use had rotted and pieces of it bent up and cracking kernels.4 None of my problems had anything to do with the gorden bars.It is very easy to jump to blame the first thing you think of until you really look things over. Thanks to Mr.Gorden for all your tips I enjoy this site. Thank you!!!! Rodney
