R40 Vs R50

In their prototype stage, I believe they were referred to as the N-3 and N-4.  They are the same machines except for the final drives/drive wheels, rear axle/rear wheels, grain bin capacity and engine HP.  The R-50 also has the inside of the cage chrome plated for longer life.  R-50 can take a 6-30 CH at 3.0 to 3.5 MPH in 200 bushel corn and when dumping at the fields end can produce 1,000 to 1,200 BPH in the wagon.  R-40 will be a little less production because of less HP and smaller grain tank (150 versus 200 bushels).

I would think it would depend on what it had for tires weather you could do 4 row wide unless you get a deal on a combine then switch tires to fit your needs.

Here's a late model orange stripe R40. I happen to know the owner. Not sure on the shape of the heads but the machine hasn't had many hours put on it since he's owned it. Still gets used a little bit every year. Price is combine only. https://rmn.craigslist.org/grd/d/gleaner-r40/6709278958.html

Thanks for the input and the link. Been running a 6620 sidehill and that pig is wide. The 'partnership' dissolved after harvest, that is why I'm looking for a different machine. Just want to get one bought with enough time to go through it before harvest next year to minimize problems in the field.

That looks like a fine combine for somebody!! A little to big for our 80 acres. Ryan

The price seems fair for that many hours and years.  Probably do a better job on hillsides then a old hillside machine, and a lot easier to maintain.

Pretty sure the R-40 and R-50 are identical in the throat width/size and the whole machine except for final drives/drive wheels, rear axle and rear wheels.

It is smaller !!.....than an N-5/6/7...….R-5/6/7....R-60/70.....R-62/72.....R-65/75.   The R-40/50/42/52 are the smallest at about 28 inches versus 38 inches for the big frame machines.

That is the first orange stripe R40 I have ever seen. I have seen plenty of the bigger ones. I remember when Deutz Allis/Gleaner was patting itself on the back for doing away with the green stripe and going orange again. Ryan

I don't disbelieve anything here; i just have a question because keeping track of gleaner combine numbers can be challenging!    you stated you think proto numbers were N3-4.  where does the R4 and R5 series combines fit into the equation?

thank you for that.   gleaner combine sales dropped here in that era!

I truly believe as the original N-series (and the P-1 processor system) was being changed/updated/improved/and fixed season after season, the Engineers took a long hard look at what not to do in the next generations combine harvesting system and the result was the P-3 processor in the new small chassis combine. The 70 inch long P-3 processor was born in 1987 with the R-50.  P-3 technology didn't get adapted into the big frame 90 inch long rotors until late 1990 in the later model R-60/R-70 machines.   By "P-3" , I am referring to:  #1. taller reversible segmented and more aggressive cylinder bars. #2. A cage with 1" x 1 1/4" holes and thicker material and less removeable doors for a much stronger cage structure. #3. a separator grate on the bottom of the left side. #4. a concave that is 100% or more larger in degrees of wrap and adjusted from the rear instead of the front. #5. helical bars that are channel iron for two edges of crop control. #6. discharge paddles on every row on the rotor  #7. more room around the cage eliminating the need for a cage sweep  #8. accelerator rolls positioned at 15 degree angle to throw the grain into the cleaning fan pre-blast of air  #9. straw chopper that utilized the same simple belt drive as an impeller did. #10.  straw spreader that did a better job of spreading fodder.  These ten changes in design were a big deal, not only in performance, but in service life of the harvesting part of the machine.  Pretty much all this remained very much the same from 1987 up thru the last R-66/R-76 series. The Super series just took these time proven features and made everything larger in diameter to squeeze even more productivity out of the 90 inch transverse rotor design.  I wasn't there watching all this happen. I just think that is how it went down over the years of development.

We didn't talk financing, but I think this was one he kept for another season. It was a legit R-50 but on the side of the grain tank it was blank...no decal.  Reede from Marshalltown might remember. It was in their territory and this particular Customer was a neighbor of my Uncles.

If he used the head from his F-2, he made it fit the R-40, because there wasn't any "kit" from A-C or D-A or AGCO to do that.
