Combines cleaner grain

Ok, more diagnostic questions. When you come to a corner and stop, wait and watch the clean grain come in the tank. Does it run steady for about four or five seconds and then empty out imediatly, or does it just slow a little and comtinue to flow in for like up to ten seconds or soIJ If your return is full is it plugging constantlyIJ or just once in the whileIJ Next time you shut down for service, if you have time could you please check the fan cutoff clearence and let me know what it is. Also, I know you dont have a lot of time, and this is probly a redundent question, but have you shut the machine down loadedIJ Some times the wheel brakes on the 14 series combines dont work so well but a full shut down is still possible and is usually the most informative diagnostic procedure for the buck. I shut mine down full after nearly every adjustment or modification i do. If you have done this, would you be willing to decribe what you sawIJ ie. seive loaded heavy to one side, stuff like that.

too wet today so no changes.no grain loss monitoror fan enlargement.the return plugged once at the end of the day in an area of daisies. (didn't get sprayed because of wet spring)the material was lite chaff andstems with a few kernels of grain.it is a true 1400 series machine with the brakeless feature.i "ve never had the courage to do a shutdown, sounded hard on the machine. so, what is the fan cutoff clearance and how is it measured. thanks again for the info.

what is the best way to sharpen the knives and set them trueIJ4.5 is flat out in 2nd gear with our 34 +30 tires.when cornering the grain runs for a while,like 10 seconds or so. thanks

I hope it quits raining soon so you can get back at it. Ok, the fan cutoff point is at back of the fan housing where the opening for the air to go to the seives. At the top of the opening the fan blades come close to the sheet metal air director. This is the air cutoff point. You may not be able to get a tape in there but if you can take off the sidewind sheild on the left side of the machine you should be able to get a fairly close estimate. It needs to be no greater than about 1_8". I run mine less than 1_16" to keep the air from continueing on around the fan. Its easy to adjust, as I'm sure you see the bolt slots on side of the machine. The purpose of getting the clearence tight is to send all the air to the seives rather than just continueing to spin in the fan. Be careful if you do adjust it, take the belt off the fan so you spin it freely cause sometimes one blade may be "high" with can hit the housing. That would'nt be good! I've seen combines come from factory with over 3_4" clearance. When combining heavy material like wheat the fan just could'nt pump enough air to keep up. On the side cutouts, you'll notice the fan blades actually disapear behind the sheild at about 7 or 8 o'clock position when viewed from the left side. This disrupts the air flow to the center of the fan. As soon as the fan blade passes the cutoff point it begins to start a new intake cycle.You'll see that at the 1 o'clock position the end of the blade is open, so air can pass inward but when it disappears behind the sheild the air can no longer travel inward, it can only be pushed foward by the blade. Its tough to describe, but if you cut out the sheild so that some blade end is always visable it will allow a consistant flow to center of the seives. If you post your email address, I'll try to send pictures of the cutout. If you'd rather not "cut up" your combine, I can definately understand and there are ways to sort of mask over the problem, there just not as effective. Also, if this problem just started this year and you never had the problem in the past then sometimes the crop is just going to make setting the machine near impossible. When you say a patch of daisys, they're probly green yet arent theyIJ This will probly coat you seives with a sticky coating of daisy juice and man that'll really reek havok when it comes to setting the machine. When I run red clover on a dry year sometimes we get a serious coating of "honey dew" ,which will be so stickky the cleaner mill has to add talk powder to get to flow through thier equipment. Its near impossible to get a clean sample. We just have to pay the piper on those years. Shutting the machine down full sounds tough but its a lot easier on the machine than a windrow slug that plugs the rotor. I'm not sure, but your manual should give instructions on a "quick kill". If not, and you do want to try it, just let me know and I'll post some general guidelines for doing so.
