They both have their strong points. The Deere has the cleaner sample. but we might be able to improve the NH with more tinkering with adjustments. The NH is quieter and has a nicer cab. We like the electronic transmission in the NH. No reefing on the big lever to shift like the Deere. The new 970 has more power and is now even with the Deere in the field where as last year the previous model lagged behind. These pictures are taken in South Central Alberta near Drumheller.

Its about time you posted pics of your NH..:) J/K Sweet pics. On the one that is a little blury though..it looks like the reel is going a 100 MPH. Ahh who cares..still a sweet combine. Is that a 36ft header? Do you find it was big enough or would a 39/42ft header be more suitable? I do find it hard to believe that the JD has a better sample. Must be the settings on the NH havent been perfected yet
Thanks for sharing.

That is a 36 ft. header. We're happy with it. Does HoneyBee/NH make a bigger one? I know Macdon does. The blurry one was taken at twilight. I was about 20 min. too late. I wanted the combine lights but not too dark. We've tried everything to clean up the sample. Rotors are as fast and as tight as possible. Bottom sieve is almost shut tight. Then the re-threshers will plug. We have 2 rows of front fillers in as well as rotor pins and trailing rasp bars. The variety of wheat is notoriously hard to thresh. The JD is set similarly. The 400 hp is a huge improvement.

Yes, you can get a 42ft model. I was just curious if you thought the combine could handle more at an efficiant rate where you wouldnt have to slow down much or would the power not be there to handle it. Im not exactly sure what to tell you on the sample as I have never run a CR. But growing up with TRs nothing can beat them sample wise. I know others know how to set up this machine so hopefully they chime in..as I dont want to see a unhappy customer.

Hi

Great pictures of that NH CR970 in action! Just curious, but why do you run two different brands of combines instead of going with one brand? I am not by any means saying that is wrong, but I find it interesting as most guys around here stick with one brand for combines, unless they are tired of one make and then switch to another brand, but trade both machines for the equivalent in another color.

The reason is that for years we have leased 1 large combine. In '05 we had a late, large crop coming so last minute, we wanted to get a second machine. Our Deere dealer couldn't source one quickly so we turned to our NH dealer. He brought us a 970 and the rest is history. We've traded since for the increased hp on NH. We like different things about both machines and will probably stay with one of each for a while.

We tried closing the bottom down but the re-threshers would always plug and the return monitor would go right to the top going up a hill. I think in our case if they can get the rotors to shut right tight against the concave we should be ok. Just need to do more threshing up front not in the re-threshers. Can't get it any tighter than 3/16".

Have you physically measured your concave to rasp bar clearance? If you're running universal concaves it should close down to a minimum clearance of 2mm to the tallest point on the rasp bar. Yours is going to just shy of 5mm clearance if the cab readout is correct. Since its not then you need to readjust your jamb nuts on the adjustment screw up top. Though you need to be careful when adjusting it down that far that the system does not try and bind up. If it does try and bind then you need to set the stops just prior to that point or you risk bending the linkage or breaking shear bolts. Also check your concentricity and levelness of the concaves. Concentricity needs to be checked at 5mm clearance at 3 points around the radius at both the front and back of each concave.

Our dealer's combine expert came out when we were basically done harvest. He said there were some adjustments. I think it is those jam nuts. We're all tucked away for winter so we'll look at it next year. Our dealer takes all machines back free of charge for servicing after the first year. Either now or in the spring before harvest starts so we'll look at the problem then.

I agree with many of the comments regarding the cleaning up of the sample. I have had this issue myself and would like to add my two cents. I have run a 970 for three seasons now. I had a 42' Honeybee which I liked however traded to a center cut 40' model this past year and really like.
At first I really complained to my dealer about the high dockage in my wheat and durum samples. The first thing you should check is what rotor belt do you have. NH came out with an updated rotor belt a couple years ago which was complete crap! The new design of this belt made the top-end of the rotor RPM's drop by about 200 RPM and thus cleaning ability was greatly reduced. My dealer was able to find some old belts to put on as many machines as possible which really helped this problem. You became SOL if you ever smoked this belt though as these 'old' belts were very hard to come by. Of course, NH had no intentions of redesigning this new belt. I believe the new machines made some updates to the gear boxes, etc. to get the rotors back up to the higher RPM's.
This does help greatly to get the RPM's high but I was not completely satisfied. The filler plates were discouraged because they did not sell many of them and thought they would actually limit cleaning ability. I ended up getting a set and I think they did a good job. As mentioned earlier, you should adjust your concaves to the tightest hold position on the first section of concaves.
I have a question also. I was always told that NH combines need to be run different then other rotaries whereas the concaves should be run as wide open as possible to get a clean sample, along with the rotors run as fast as they can. The threshing ability comes from centrifugal force. This centrifugal force of the rotors throws the grain against the concaves instead of grinding it through like other brands.
During good hot days the concaves can be really opened up which also greatly increases capacity.
You can run your concaves in the closed position however this greatly reduces capacity along with high risk of cracking of seeds. The opened position really helps capacity and with proper settings the samples are very clean with absolutely no cracking of seed coats whether it be field peas or durum/wheat.

The new 08 9070's have the rotors up to 1450rpm...which will help out a lot!

Jester, that will be a major improvement, especially for HRSW. Tr/cr's have always been the easiest combine to not damage grain with, I don't know why NewHolland messes with lower rotor speeds.
