SW Manitoba. | Geringhoff claims their roto disc header chops the stalk in such a way that stubble damage on tires is way less versus the deeres or other brands that use lawn mower type blades to cut stalks. Does anyone have any experience on this? Any truth to it? How would you rate the quality of a Geringhoff header when compared to Deere while keeping price and resale value in mind? |

North Dakota | I have been running an 8 row Gerringhoff and have not had any problems and have been happy with the head. I will be going to a single disc drill for next year so my head is for sale. I dont want all the stover on the ground. I thought I would throw it out there in case you are looking. My e-mail is good!! |

Southern, WI | we have a rota disk and what they claim is true, the head does a good job of shattering the remaining stalk so decomposition can start quicker. weather or not it wears less on the tires i don't know, we still notice some damage but it cant be any worse than the others. if you plant pioneer that is one heck of a stub left either way;) |

Northwest Illinois | Rotadisc cuts the stalk up and down rather than sideways like a lawn mower blade style chopper would. The stubble from the Rotodisc is no worse than a conventional knife roll head. The stalk is left opened up longways so it rots down alot faster. Also, the Geringhoff takes alot less power to run than a lawn mower head. |

NW Central Ohio | I looked at both of the Gerringhoffs yesterday from the bottom up....I couldn't believe the design, quality of workmanship and craftmanship of both. The only thing I can say about the Roto-Disc model as opposed to the standard model...is boy are you going to spend some money if you have to rebuild the rolls and discs. Comparing it to the Deere chopping head...I would take the Gerringhoff for it's design, and low HP requirement. |
|

|
Northwest Illinois | The cost of Geringhoff replacement parts are directly relative to the longevity they provide... the way it should be. |

Central IL | We have our first Northstar 12R30 folding head and I am disappointed in quality. It is a 2012 and we have 400+ acres on it. Major slow on the fold, 7 minutes. The dealer came with new valve stack and it does not have enought ports. Geringhoff tech are scratching their heads on this.
We have to replace 2 of the 3 augers because the internal drive shaft was not welded correctly. We welded them up because it takes a week to get parts from North Dakota.
We have new orifices coming for the deck plates because they move so fast. It jumps 2 to 3 numbers with a push of the button.
Overall it is working but not overly happy.

Northwest Indiana | RE: Slow folding, dont know which machine you run, but on a Deere an orfice can be drilled out or changed to speed folding.... |

Southern Ontario | Resale value on Geringhoff heads is quite good. That is if you ever sell it once you have one. Once you get a Rota-Disc you probably wont sell it. Unless it's to get a bigger one...

|
Chebanse, IL..... | How do we know (factually) the hp requirements of either head & how it's obtained?
Just wondering how that's rated & who did the rating....University of Nebraska? |

York, PA | SSI. DeereCraig is correct. I know of a bunch of these out in my area and if you drill the orifice you'll fold in 2 minutes per one owner I know. The deck plates sound like they may be plumbed wrong. I can't say I've ever heard of it. The elite series are new this year. Geringhoff will make it right. We traded in a 12row Rota-disc that had 18,000 acres on the original gathering chains. The fellow bought an elite series. Quality has been excellent. Hope they get you going soon. |

I sense a set up problem with your head. I don't know a darn thing about them, but if the deck plates are way too fast and the fold is way slow, would sound to me it wasn't assembled right.
Sounds like if the hydrualic speeds were switched it would be about right. Maybe the electrical AND the hydraulic are both switched, allowing the correct button to do the correct function, but the proper oil isn't. I don't know how its set up, but switching the wires and hoses on those 2 functions would be my first thing....... |

South Eastern ,ILL | I have a 2012 Gerninghoff North Star 12 row ,30" w/crop sweeper reel. Like the head except the
snoot were very weak in down corn. I had to reinforce the shoots with strap steel to finally get them
to quit folding under or bending.The auger,snapping rolls,gather chains,and side augers are a step
above the competition.
Gerninghoff just needs to make a stronger snoot and soon. |

| Not perfect, but still the best chopping cornhead out there when you look at build quality, drive design, residue sizing, etc. Yes, they do take less power, and yes, they do leave the stalk stump in a condition that is less harmful to tires/tracks. |

We're interested in this "less power" thing statement. Where can we find these facts presented?

No Chinese parts on Gerringhoff!
I'm a bit confused on this quote... What doesnt have Chinese parts on it these days. It doesnt matter what color the equipment is they all have Chinese parts on it.
I'll take my Geringhoff over your whatever head any day. |

It's in the Rota-Disc Elite brochure on the 5th page. If you dont believe the statement get a Geringhoff head and try for yourself. It is true that they require less HP than lawnmower style heads.

I would have to argue, we went from a 8 row G to a 12 row Deere on a 9860 and didn't notice any difference. |

NE SD | That's not what Carson said last year when he went from his Hoff to a neighbors 612. |

WCIL | In ideal conditions there is no better chopping head on the market. It's amazing how quick the residue behind these heads breaks down. In less than ideal conditions you couldn't give me one! That being said there are soon to be 3 used 18R20 Rota Disc on the market. Tired of looking at neighbors beautiful fields after stalk master. |

| Simple: same combine, same crop, same year, same field. Swap same size heads and note power consumption/reading in cab or even max ground speed obtainable when limited by power required by chopping head. That, or install the tooling on the power shafts of the headers being compared and make ground speed identical - then you can compare the effects of groundspeed vs header type as well, which is also where the RotaDisc tends to do quite well. If all other factors/variables are the same except for one, (header brand), you have some pretty conclusive evidence. The amount of difference may vary depending on some of these other variables, but have done enough repetitions of this comparison to know. When working with some projects involving chopping cornheads, the Geringhoff was a frequently encountered benchmark, I think largely because it's been in North America for quite a few years and are well established. |

NW central IL | but put a 70series or newer combine on a jd chopper head and it gives you the hp to offset the hp difference...just burn more fuel...they pull easier, but i like my deere head in down corn situations.....neighbor has gerringhoff on cat 760 yesterday. my corn was dryer and down worse then his. i ran a consistant 3.8-4.2mph....he ran 1.5-2 and was backing up every 150-200ft.....he has the cones and flappers for the middle rows...also another neighbor is busting the crap out of augers, whats the deal with that???(hoffs) is there a issue with them this year? |

| Not sure about any widespread auger issues - if there are I am not aware of them. Advise your neighbor to remove the stationary/hook knives at the front of the RotoDisc - in down corn this is primarily what impedes the entry of the stalk into the units. He'll still be processing the stalk that runs through the rolls, but it should greatly improve crop flow. Then he can flatten out the angle of the cornhead quite a bit at the same time. |

Chebanse, IL..... | By God Turnbull, you're right, there it is....right in the Geringhoff sales brochure on page 5 which was probably done without prejudice, completely composed by Geringhoff with tests done by Geringhoff. The graph clealy shows the increase in speed labelled in mph on the X axis with a clear increase in hp demand on the Y axis, however with no label....just an increase. Not sure if it's 1 or 10 or 100. I'm guessing it was just an oversight to not put the label on the Y axis. That's the exact information I was looking for. Now I know how much hp it takes to run each brand of head.

MN | had a hoff and it was a good head. chops the stalks up awesome. that being said we are now on our second deere stalkmaster and the deere head saves enough corn to pay the to boot price. |

| To your question, Ron, yes, these charts do exist. The manufacturers themselves are the ones who do the studies as header power requirements can be direcly measured with a device that is installed on the main power shaft/pto driveshaft of the machine. The overall shape and general trends reflected in the one that Geringhoff publishes in their brochure is pretty accurate - they leave it at that so that the JD team of lawyers can't come after them for publishing specifics - that would likely open up a can of worms that they just plain don't want to tackle. I have some notes on some of these studies from a couple years ago, but I cannot simply put them on the internet here for all to see either - these are the property of those who did the study and for whom we worked and are confidential, which is why I can talk generalities but can't go much beyond that. |
|

|
Chebanse, IL..... | Well, OK...if you have the specifics, what are the specifics. Again, there is absolutely no valuable information in the graph presented. Just that "ones a little more than the other when they go faster (which in itself should surprise no one)....". Is that the scientific data you presented?
I still say "advertising gimmickery". If the figures are indisputable, then they should be presented. Now they say they have the data but we can't tell you..... Why even bother? How can anyone sue against the truth?
Helps me understand why they established the U of Nebraska testing stuff a long time ago. |
