St John Welding has a modified enclosed rotor for your combine. Can't help you on the others.

Yes there is and I understand from Gleaner service that it makes it a little monster in corn. I believe this in that them short rotors put us back in the combine business. This started with the R50s and they worked so good right out of the box. This got us going on duplicating the design within the short rotor into the long rotor. Both rotors run same diameter cages and cylinders. Problem with long rotors is they ran same pitch helicals as short rotors which caused alot more all ready threshed crop to be ran over concave again. They were also tring to discharge material well before discharge opening. Short rotors shared same problem but to a much less degree. I can see with the 24" CDF that there is room to shim helicals and still not pinch cobs between helical and cylinder bars. Shimmed helicals will handle material even better. I can see next step on longer rotors especially in corn with 25" rotor and steep pitch helicals will be to space helicals another inch or so wider. Sorry I kind of wandered away from your question!!!

G'Day Dan Was Wondering if you use the Blade sweeps in R42_52 Short rotor machine's and what to expect if you put steep pitch helicals over concave on short rotorIJ looking at convincing a neighbor in hyping his short rotor machine!! But some guy's around here are very conservative!! Don't like to mess with a factory setup to much!! Rolf

So Dan what your saying is:yes Gleaner DOES make the cdf for the R-52 (Mines a '98 model) machine or is it still in the experimental stage also has any here had hands on experience with the St.John or sunny brook version for the R-52IJ Thanks for all the info so far Plan on going to the farm show when it comes to town and talk to the guys there just want some info to at least sound like I know what I'm talking about. My machine is used in Wheat corn soybeans and Milo (southern Il.area) Thanks for all the help so far Just want to make my little machine the ENVOY of the neighborhood with all the green and red around me.Have done some of the moods so far but want more, thanks again Bob

Yes most short rotor machines now have sweeps. This time it boiled down from what we found to work on long rotors. Most all these short rotors are in edible beans thus it makes extra sense to install sweeps. On a 42-52 it takes a very short piece of helical to extend second one from gearbox over feeder. The 40-50s had shorter helicals so it took a bit longer extention and made it a little more important to at least extend that second one from gearbox. To help prevent any second pass over concave you could start at gearbox wall with steep pitch like on long P3 and it will clear top left corner of feeder. One more steep pitch running paralell to it makes a nice setup. I believe tbran has a few running like this also. One thing I really like when I look at your pictures is the closing up of the top of feeder opening into cage. I know of a guy in Canada that did the same thing and he reports less feeder problem and or back feeding even though I don't believe he has did anything with his helicals on his long rotor except maybe the third helical extention over feeder opening. This guy may all ready have the extended cylinder bars depending on how new his 52 is. I don't blame the guy for not wanting to monkey with factory setup but if he understands that machine is setup the best way the factory knew at the time for all the crops and conditions it might get into he might understand. If a guy wasn't open to change we would still be threshing by hand. I wonder if John or the dealer with freshly hyped machines has gotten going yetIJ Have a great harvest

I would say yes it is or will be available. I'll let you know if I find out different. We did not get our long CDF in time to give it a try this year. I have only heard good news about the long CDF in corn and soybeans. Don't know how it did in wheat and milo. Couple thing to remember when comparing jobs of one rotor to the next. Condition of rotor removed, how many reverse bars, bars extended to discharge yet, any sweeps on it, any helicals renewed or moved, ect. Sorry I can't relay any info on any other rotor other than standard with extended bars and sweeps in R52 and smaller machines. I do think you can take what you learn about the other rotors in large machines and expect similar results. Hopefully someone can feed you some more info than I was able to. Good luck

Hi Dan. Had a quick phone call from John around thursday last week. He had not got going at that stage as it was raining every second day in his part of central Victoria and still is, and his crops were still green. He is really champing at the bit waiting to get his hypered up, hotted up, double sweeped monster into some pretty good irrigated crops. Haven't heard if his agent [ A very good operator ] has done any thing yet.

Here's what I find on CDF in a bulletin this summer. Set up with 2 reverse bars in row A (row next to discharge) on both the short and long rotor. No other reverse bars in short rotor. Skip row B on long rotor but install one in row C and one in row D (row next to gearbox). This is suggested placement of reverse bars for corn, soybeans, wheat, and milo. If you should have loss with short rotor it suggests a single bar in row B and another single bar in row C (thats the one next to gearbox on the short rotor). Each rotor does come with standard set of knifes with room to install more. It suggests to carry some extra knifes on hand in case you should need them for something like green milo. You could look back a few monthes to find some spuratic comments on CDF or likely someone with experience will comment soon. Good luck

We've built 2 rotors for R42_52 machines -- They're somewhat more rare in this area than the bigger machines. At this juncture haven't required any reverse bars. However, in consideration of the shorter separating length of the cage_grate, we installed sweep_agitators as opposing units -- 180 deg. across from each other, and both beginning at the R_H side of the separator grate. One operator removed his sweeps to see what would happen and experienced a mild rotor loss in soybeans along with some congestion at the discharge. Apparently the MOG wasn't breaking up as well for separation. We also built a rotor with 8 rows of bars in this manner several years ago, but added provision for short sweep additions at the discharge -- these were never used since we had eliminated the discharge paddles. Cleanliness of samples are much better with the 6 bar rotor, and the intake is much smoother with the wider spacing between rows of bars. I question the use of more knives in milo, etc. Seems to me that it would be better to break up clumps for separation than to chop them and increase shoe load.
