Was just buzzing around youtube and typed in cr combine and down the list was 2 videos part 1 & 2 showing a seal kit for the sls for CR combines. Does anyone have any info on this? Does my 9070 have it or is it aftermarket? Video is dated like 2005 but video has only been on youtube for 4 months So lets hear it....whats this all about?

The Air Flow Control is after-market. If you have seen the video you know have seen what the problems are when the air isn't controlled. I know that there are a number of red machines running the kit now too. Farm Journal did an article on the system about a year ago. What was your impression after seeing that video? Hopefully CNH will put it in at the factory because it definitely helps. There have been others comment about it's benefit on this site earlier. That video is at www.newhollandrochester.com.

we noticed there were whole heads in our grain tank on our 9060. We searched and searched try to find where they were coming from we took concaves out looking for holes and wondering how they were getting in the clean grain and not in the return. I never thought that they may be falling off the shoe and into the clean grain. How much is the kit and how hard is it to put in.

I am the service manager at a New Holland dealership in Nebraska. We have been putting this kit in all of our combines for the last 5 years now. The biggest problem we were running into was overloading the top shoe and walking grain out the back of the machine. This was caused by air escaping out the sides of the self leveling shoe rather than being forced through the sieve area. We run mostly 970's or 9070's in our area. Most of our problem was in corn with 12 row heads. The kit comes out of a dealership in Rochester Indiana. It is aftermarket, but we have been trying to convince New Holland to install it from the factory since the fist one we put in. We have had 2 970's in the field at the same time... corn- 220 bushel, 18 moisture. I could easily push the machine with the air flow control kit 1 mph faster with no loses. If I tried to get the same production out of the other combine, there was corn all over on the ground, all coming over the shoe. I refuse to sell a combine to a customer without this kit.

I am the NH dealer ar Rochester and we developed the kit here after we couldn't get shoe performance that was acceptable with the introduction of the self-leveling shoe in the CR combines. I have over 150 of these kits running and all of them have been installed by dealers or owners. I have yet to have anyone have a problem with some crop because of the seals, and the benefits have ranged from 'dramatic' to 'just improved'. I've had dealers call because a customer was going to switch brands over performance of the combine and have improvement good enought to completely satisfy the customer. I can provide plenty of references at the dealer level or user level. There were 10 kits put in red (8010) combines for 2008 and it seems that the improvement there is at least as good as in the NH machines. Again, I can provide references. The kit sells for $780.00 with an additional $30.00 for UPS freight. The first kit will take about 20 man hours but my guys have it down to 13 man hours to install. Once it's in, you won't know it exists except for how much easier the combine is to set and how much less sensitive it is to changing crop conditions. This kit, if the company would install it at the factory, would likely not cost a dealer more than $750.00 as a factory-installed option. There are a lot of Case and NH owners (and dealers) who don't have a clue how good the self-leveling shoe can be.

Is this kit really needed with the enhanced shake shoes on the newer combines? I thought i heard they added some extra air diverters at the factory. Do they improve the bigger or smaller shoe combines more. I would think Case's fan would provide better air then NH big old paddle type fan and probably does not help case as much as NH.

The enhanced shoe certainly was an improvement, and the lower sieve seal and a triangular opening cover that were originally part of the Air Flow Control have now been added at the factory. (the factory lower sieve seal is metal whereas I use a rubber seal) These attempts at controlling the air don't address the main air loss areas as you'll see in the video on the website. The maximum air, and whether the CIH or NH fan has higher maximum airflow isn't the issue. Once the Air FLow Control is put in, operators consistently report that the needed fan speed is about 100 RPM less than they'd been running (CIH or NH, doesn't matter). The lower air speeds help let grain thru the sieve but still keep MOG suspended and headed out. Changing crop conditions just don't impact air flow as much once the seals are in place. It's my impression that the improvement is at least as much on the CIH vs NH machines but improvement is significant in either brand, which is what you'd expect given the fact that the shoe design is the same. I don't think that there's much difference in the amount of improvement in the 52" or 62" shoe but it I had to pick on, the 62" shoe is helped more.
