Combines Steep pitch helicals w Sunnybrook Gen 2

[tbran]

yes, we have been installing three steep pitched helicals over the thresher side to prevent this. Very good results. No loss increase. Email Nathan @ as to exact location and cutting of last helical.

Thanks for the info, tbran. Have you heard of any conditions where there was a negative to doing thisIJ Should you put them in without spacing them closer to the rotorIJ Checking with parts there is a 68 degree bar kit($885),but I think that does the whole cage and I don't think that I would get enough seperation then. Any experience from anyone on thisIJ I am using loewen sep. cage grate. I am going to a 12 row 22" Gehringhoff next year, so anywhere I can free up extra HP is a plus. I also believe this would reduce cob breakup_improve ease of keeping small cobs out of corn sample. Thanks for all help.

I have installed steep pitch helicals all the way thru on 3 different p3 cylinders. The first was a lowen replacement that went into an n5. With this set up their is no sep grate and the helicals do not end at the bottom of the cage. Now it will push a 24' platform in 50 bu beans at 4+ mph with no loss in corn or beans. 1st year was ok in wheat, this year seamed to be a little loss. The second is a 96 modle 62. We ran thru wheat, beans and corn this year with no loss. this machine has the extended bars, wires pulled from sep grate and 1" spaced rasps on the left 2 rows of the cylinder. This machine is pushing a 25' 500 at 4.5 mph which is what the owner wants to run, but he doesn't slow down when he hits green weeds or green stems. He also said it took care of the cob breakage in corn. 3rd machine is a 2002 stock R72. The only thing we did was to add the steep pitch helicals.(all 3 have 2 reverse bars)We are demoing this machine in beans. In good standing 50 bushel beans we can run a 30' header at 5.5 mph all day long, but we can run 4.5 after dark. I think you can run your cylinder faster because of the helicals which adds great capacity. Non of these helicals are spaced out. When these machines hit a tough wad of stuff it seams to be thru the cylinder before the govenor has time to react. Email me if any more questions. Nathan

Thanks for the info Nathan. I won't be making these changes til summer, but I will keep your contact info when I do it. Did you get the helicals from Gleaner parts(kit or by part numbersIJ Chrome or blackIJ) or is there a better wayIJ Using the Sunnybrook rotor without reverse bars it will be interesting if we will have no losses out rotor. I am game to give it a try.

I got the parts thru Gleaner parts by part number. I would not recomend black, even tho they are cheaper they do not last very long. Nathan

Steep pitch and 68" are the same thing. There may be a couple kits mentioned for the 62's and 72's for edible beans but they would be chrome helicals at normal pitch and forward cylinder bars. We have installed lots of steep pitch kits with some extra helicals added where we thought necessary. We have shimed helicals by 1_8" on many machines and even 1_4" on one. I don't see a whole lot of benifit in shiming but with the steep angle it looks better if they stand up just a bit higher with 1_8" flat iron. I haven't shimmed any in at least a couple years if that tell you anything. I don't see an earthshaking improvement with steep pitch in just thresher side or all the way threw but it does make more sense in thresher area to try prevent to much material from making double pass over concave. When I install steep pitch I install first helical right where original first one started and it ends right where third helical did and that would be right where helical extention over feeder opening starts. You wonder how the steep pitch will help in tough green stemmed beans and I would say nothing earthshaking. There are many ways to get green material to flow easier but number one would be cylinder speed and forward rasp bars for now. After tring about every angle helical, any number of helicals, anyheight of helical, any width of cylinder bar rasp, any height of cylinder bar or rasp, various degrees of blanking off concave or seperator grate, ect. ect. I think were finally onto something. Grant it this is for conditions when nothing else is running or maybe should be running and has only been tested in a couple crops with very slow cylinder speeds. We'll need another year or more for R and D but it looks like the Gleaner will be going where it never has before. For some reason I think I have opened my mouth to wide again but I hope not. Happy Thanksgiving everyone!!!
