| Was thinking today about what would be a descent trade off in size/capacity to F2('79) We don't have alot of acres and only run corn and beans. Not looking for capacity so much as gaining YEARS on a machine. Hoping to stay with a 4/30 corn head and whatever grain table for said machine(we run a 15' on the F2).I don't see alot of the '42's on Tractor House and not yet Googled specs for one. Wondering if anyone has experience with that small of a rotor machine. Thanks |

| Isn't the R42 the rotor equivalent of an L/L2/L3, class-wise? |

| The way I understand combine "class" only has to do with BIN CAPACITY,, not anything to do with threshing capacity.. |

I am more concerned with the physical size of the machine LOL! We are somewhat limited to what will fit in the 115 year old bank barn doors, if you know what I mean  .

Oh wow, yes I understand what you mean. I've only seen one R42 in person, and it was at an auction. Looked good, but went dirt cheap. I think an R42 is about a 1.5' taller than an F series, but I could be wrong. Michael, I thought it was hp and separator size, but maybe not?

You'll just about double the capacity with a R40/42 than the F2. The R40-50 was supposed to the place of the M and L's which they did above and beyond in capacity wise since they had more horse's to them. A 42 depending on year might have a little more capacity than a 40 would have. ------------- 8070FWA,7080 BlackBelly, 7045,2 200s,D19,D17,G, WD,45,UC,7 AC mowers and lots more!

Take that with a grain of salt, but I think that's what I heard. Providing the bubble up auger is folded down. I don't know the width. I just know the one I saw at the auction looked a good bit bigger than an F series. I bet someone else will know for sure. If you're just looking to take years off and don't necessarily need more capacity, depending on how "new" you're wanting, I'd look for a good green stripe F3, although I personally don't like the looks of them.
Or maybe, since you've ran your machine and probably know what's been done to it, you might consider having it ran through a shop. I've heard of a lot of Deere guys doing that, of course, they almost have to do that |

Its horsepower, classes have changed over the years. N/R 7 class 7 combine rated at 270 hp would be considered a class 6 or maybe even class 5 Most class 6s are 310 to 340 hp now and each class is spaces 70 to 100 hp apart from what i get brom brochures ------------- 8070FWA,7080 BlackBelly, 7045,2 200s,D19,D17,G, WD,45,UC,7 AC mowers and lots more!

If you buy a R42 DO NOT BUY A DUETZ POWER ONE!! It would be a step backwards motor wise. I know of one for sale near here for $20,000 with both heads and it has a Cummins. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

| Can a 4/30 head be run on a 40/42? I think I understand that they are capable of 6 rows, but would the 4 row be a complete waste of the combine? Our 4 row fits in the barn door now(15'),but the 15' table won't. We plant with a 4 row planter for what it's worth. Thanks for all the input. |

40/42's have smaller tires. I have seen a few with 430 heads. We ran a 438 on our 50 up till 08, it wasn't enough but <130 bu corn didnt help either. It depends how your yields are . ------------- 8070FWA,7080 BlackBelly, 7045,2 200s,D19,D17,G, WD,45,UC,7 AC mowers and lots more!

| When those of you that transitioned from conventional to a rotor,what was your biggest learning experience with the rotary machine? Are they a completely different animal or are there some similarities? |

Rotor is fairly similar to a cylinder machine for learning settings. My local dealer told me that on a rotor to always remember that too fast cracks and too slow explodes. In reference to the corn cobs coming out the back and grain in the tank. If the cob looks like it "blew up" (or pulverized) then the rotor is running too slow (if the concave is set correctly), and if you are cracking the corn in the tank then the rotor is running too fast. The basic settings he gave me for setting one are: break an ear of corn in half and measure the cob diameter and set the concave clearance 1/8" smaller than the cob diameter. Next start out with the rotor speed set a little slow (on corn you can probably start around 250-300 rpm) and keep speeding the rotor up until you start to crack corn then slow it down 50 rpm and the rotor speed is set. When running beans I usually on my R50 will set the rotor at 600 rpm then adjust as needed and the concave around 3/8" and adjust as needed to thresh the beans but not split them. On beans and corn I run full air, but I don't know if maybe on an R40/42 if you would need to close the air down a little to avoid blowing grain over the rear.

| About 13 years ago we upgraded our 81'F2 15'head to a 98' R52 20'head. Capacity of the R52 is much more, you can go faster, cut more in a day plus the Gleaner R-2 series combines have really nice cabs. With the bin extensions folded down the standard R52 combine is 2" taller than the top of the bin extensions on the F2 (I believe a R42 and R52 are the same height). That being said, we eventually missed having the F2 around and later bought a nice low houred one owner 83' F3. I have been told that capacity wise theR42-52 is more comparable to a M2 than a L2. We feel like for our small farm the R52 is a nice fit and a good comparable upgrade from the F2, I think I would feel the same about a R42. A lot of times dad and I run the F3 and R52 in the same fields. Both are very good combines, just different machines that work just a little different. |

| Thanks bharper! Can anyone tell me what type of stone protection a N/R series machine has? Is it similar to the conventionals with the rock door or completely different? I have read posts on A/T of guys ingesting rocks in their red/green machines and incurring $25-30 grand worth of repairs?? |

| Thank you. I asked guys "over there" what their combines had for a door and didn't get an answer. I thought maybe a rotor machine could not utilize a door like the conventionals. |

I talked to a Deere dealer at one time about what they did when their combines ate rocks. They said they usually get by by re-balancing the rotor, even if there's a big dent made. Saves time and money I guess. Of course, in this area, our "big" field rocks are baseball size, and those are few and far between. Not sure what you've got in Michigan. |

| wish my IH rotor combine had a rock door/trap like my Gleaner did. would have saved me a combine! not a lot of damage to the rotor or cage, but it smashed everything else inside the combine! insurance paid $6500. for the damage (not full amount of estimate), but was able to buy another combine for $3500. and still had the other for parts....engine,hydro,tires, ect. |

I have a question for anyone who may have a Gleaner R42,R52,R62 dealership sales brochure. Q - What platform header width sizes were listed in the brochure for these R 2 series combines? I mean - if an F2 cuts with a 15' and a R52's capacity is twice more, then was it offered with a 30' header? |
Posted By: DanWi
Date Posted: 02 Feb 2018 at 10:23am
| 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?

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". |
