Just a guess on capacity comparison and double the head size. Is that yields increased from the time F's were made till they came out with R's. The rotary had more capacity on hillsides vs a cylinder machine. and sometimes with the cylinder machine you really slowed down with the rotor you would be able to have a faster ground speed.

Yes, I used to think that until I rode with someone else whose gleaner cut soybeans at 4+mph instead of 2-2.5mph. It clued me into realizing that my past way of thinking was my gleaner's most limiting factor. In 2017, my gleaner K2 equipped with aggressive cylinder bars & 13' flex wobble drive header, harvested 65-70 bushel soybeans @ 4-4.5mph. It's header cut five 30" spaced soybean rows that had about 30-50% green stems, but still testing 12% grain moisture. I pushed it to 5mph, but then the sickle was pushing a few stems over & not cutting them. I consider that amazing since it only has a 27" cylinder... Wouldn't an R 2 series' capacity handle much more?

Sales brochure says up to 30' rigid headers and up to 24' flex headers for models R42,R52,R62 and R72. Corn heads R430,R438 and R538 for the R42 and R52. R630 and R638 for R42,R52,R62 and R72. R830 for the R52,R62 and R72. R838,R840 and R1230 for the R62 and R72.

I don't have a brochure but my R52 manual has specs for the 42 and 52. It states that they were offered with a 15-25' flex header or a 18-27' rigid header and a 430-638 corn head.
Personally I think 25 or 27 foot would be a good load on a R42-52, but have never ran that big of head on one. I think the you may have trouble in tough conditions getting the crop through the throat. The R42-52 have narrower throats than the R62-72. Also I don't know how the combine with standard tires would work picking 4 - 30" rows of corn. We don't pick corn with our R52 but I believe you have to lift the ladder in order not to knock that left row of corn down.
I have one neighbor that bought a 94' R42 from a Gleaner dealer out of Iowa. They recommended to him using a 16 foot head on the R42. I have another neighbor who runs a 96' R62 with a 25' head. He thinks that combine would easily handle a 30' in our SW Missouri farming conditions.
I have never felt like our R52 with a 20' header was overloaded at the throat, rotor or shoe and I don't think I would want a smaller header on it. I believe after 96' Gleaner made the shoe longer on the R-2 combines and Cummins engines were added in 94'. I don't know how the older combines with Deutz engines and short shoes compare to the newer ones.
A question was asked earlier about the rock trap on rotors. It is about head high right below the rotor. It takes two bars to close, and I think it can be a bear to get latched shut but it can be done. In 13 years I can only think of ours coming open a handful of times while I was on it. Dad was under our F2 once and the door swung down and hit him in the head, he almost passed out.
As far as working on the rotor combines, I feel that they are just as easy to work on as the F2's and F3's but like I stated earlier, they are just a little different. If you know what you are doing you can get the rotor out in about 30 minutes.
The R42-52 is 139' tall to the top of the cab.

At one time we had a R50, with a 630 corn head, 20 foot Flex, and a R70, with an 830 corn head, and a 24 foot flex. Both had Deutz engines, neither one gave us any trouble. In fact, we at one time, had a lot of Deutz power units, not problems with them either.

I know this is a different colored machine, but it should be about the same for all brands. my IH 1440 could handle a 20 ft head easy in soys, but due to my steep hills I traded it off for a 13 ft header,(wish I could have found a 15 ft), but the ground speed was the same as with the 13 ft as it was with the 20 ft, because otherwise I would push the stems over before I could get a good cut. my Gleaner "G" also had the 13 ft header as did my "K" combine, and the ground speed was the same for them both too! all the 13 ft headers took 5-30 inch rows. the renters here came in with their 20 ft header and there are ALOT of un-combined beans still in the fields. and they had to travel fast so everyone driving past on the highway could see them! they also pushed a lot of stems over and left them in the fields! the best combine for cutting the stems off at the ground was still my old "K".
