| Have NO experience with the crop "here", and am away from the farm to look into the "OM"until next weekend, but can anyone comment on the "basic" settings for sorghum?? Is the crop similar to oats/wheat as far as cylinder/concave settings? Thanks |

I would start with wheat settings and make micro adjustments from there! ------------- http://machinebuildersnetwork.com/ |

I don't know them off the top of my head, but at least for my All-Crops, they're not too far off from wheat. Concave spacing is slightly larger, and I think cylinder speed is just a bit slower. But...that's going off memory from 3 years ago. Take it with a grain of salt. I do remember I had to raise the cylinder up a bit more than what the book recommended, as I had trouble at first keeping the grain from being chipped. Raised the cylinder a bit and slowed it down and that fixed it. Don't be surprised if you have to adjust things a few times to get it right. Sorghum is kinda hard to clean sometimes because the branches of the head, as well as any stalk you cut off, can easily break up into material about the same size and weight as the grain. I'm surprised to hear you're growing it in Michigan! Didn't think there would be enough GDU's that far north to get it to physiological maturity. Usually, that stuff's referred to as "Great Plains corn" down here. We don't get enough water for real corn, so the drought-tolerant sorghum does pretty well. |

I should have made a comment that we did change our OEM cylinder bars to aftermarket wide spaced bars 2 seasons ago(should have done that 15 years ago ). Thanks for the input guys !!

| Lot of grain sorghum raised in St. Joseph county Michigan, works well with seed corn production. Used on the dry corners of pivot irrigation and as crop for setbacks from other corn, either seed or commercial. Used as replacement for soybeans. |

| Old, do you happen to know where they market their "corner" crop? I have noticed the same thing at the old ST. Joseph farm in Granger(IND.) last fall. |

| 1/4 inch on cylinder, 700 cylinder speed. Don't be surprised if puts some on ground. Leaves go out the back with grain laying on them. Not a pleasant crop to set a machine on. MACK |

Oh come on Mack, surely you can get 0 loss on Milo ! :-) There has never been a call about grain loss on high moisture mile or maize .... ha ... used to pull what little hair I had left out on rotor losses ... biggest issue we had was to get customers and operators to understand that less than 1% loss is expert setting quality . IF one looks on the ground , a 1/4 bu to the acre LOOKS like a massive amount.. The issue is compounded by us operators who see a low hanging head and dip down to get it and in the process ingest a header full of green leaves which as you said are magnets for those little seeds. Run the cylinder as fast as possible until it starts to crack then back off - stop the machine and look over the walkers and determine if ALL the grain is threshed out - many walker losses come from un threshed heads being threshed by the chopper - if there are grains still in the heads lower the cylinder.. remember speed cracks. The op man - in my opinion lists too much opening for the top sieve and too close for the bottom or sieve. We try to start at about 7/16" to 1/2" on the chaffer and about 3/8 to 7/16" on the sieve. A wide top setting and closing down the sieve shuts off the air in heavy crop...and it walks out - there needs to be a 6-12" 'rooster tail coming off the end of the shaker shoe... ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

| That is a funny story. It’s called competative edge until you get caught. Then it’s called cheating. Lol |

That's a good story! But, is the Gleaner really that bad at rotor loss? Because if the other guy who got "last" was because of your loss, then what does that say about the Gleaner as a combine??

All of the rotary machines are bad for rotor loss I don't care what color they are. We have a 9550 walker machine and we don't leave much corn. All of our neighbors have the newest and the latest Case IH and Deere rotary machines (no AGCO dealers around here anymore) and those things sling corn all over the place. I always dove hunt on the farms they rent because there are more birds in their fields than ours. lol One of our neighbors bought a new Case IH combine a couple of years ago and couldn't ever get it to stop losing grain and he finally got so fed up with it he went and bought a 30 year old 9600 that some guy who quit farming had left sitting out in a field for a couple of years and put it back to work.
