Combines Helicals in edible beans

[bakes]

make sure that all reverse bars are removed from the cylinder, the reverse bar cause the damp bean straw to wade or ball at the slow cylinder speed required in combining edible beans. The wades will push the side of the cage out. At the slow cylinder speed required not to crack the beans the straw does not move threw the roter well therefore the need for the channel helicals or stacked helicals.

Hello Wiley, I have an R7 with the Sunnybrook rotor.I double-stacked the flat helicals three years ago, and crop material now flows much more smoothly,rumbles less and takes less boost, especially in tough conditions (although I don't grow beans). Double-stacking (to me) means adding another set of helicals on top of the original, therefore increasing the helical thickness to around 3_4". My kit was ordered by my dealer from Sunnybrook, and it included all helicals, bolts and instructions-you will have to remove the rotor to double-stack the helicals, however. Sunnybrook's URl should be shown in the link below (www.sunnybrookwelding.com). No doubt there are other dealers who can get you the same type of kit, or the newer style of channel helicals. Hope that helps. David

In edible beans there are extra helical bars over the top of the cage. I do not do edible beans but put them in anyway.

Double stacking means that you take some old flat helicals and put them under the good ones to make them more agressive. You double stack the flat helicals that are in the thresher end of the cage (above the concave) plus you add a couple of extra rows (also double stacked). If your helicals are in good shape just get some used helicals out of a salvage machine for stacking. If you are installing the channel helicals in the seperator end you will have plenty of spare flat helicals for stacking. Once you have the rotor out, climb inside and lay on you back with the diagram and look up at the helicals in the thresher end, it will make allot more sense.

Yes you need to part with standard helical setup for sure. Double stacking or shiming with 1_4" flat iron formed to back of helical will do basically the same thing. Along with double stacking or shiming you need to install the so called green stem kit which is a package of helicals to add to thresher side which includes three helicals that hook up the steeper pitch thresher helicals to the shallower pitch seperator helicals. Another option is a channel iron helical kit that runs the same angle threw thresher and seperator side and Gleaner pushes it as a kit for edible beans and green sunflowers. I wish they wouldn't of pinned them names to it and we would of been running that kit since the early '80s. That kit is chrome and works well in many crops. We don't us the retarder bars or angle iron flow retarder that comes with that kit in beans for fear of cage problems. There is another option out there for channel iron helicals and that is a dual pitch kit from loewen. It follows the standard pattern of flat iron helicals and covers the area that the so called green stem kit covers. Again remember chrome if thinking channel iron helicals and edible beans. Of course it's best to get rid of reverse cylinder bars. No rotor grumbling allowed and pay attention to what machine is doing with little in hopper. Remove paddles from rear accelerator roll on N6 to prevent throwing them down to hard if beans are to very dry. Some guys will slow up clean grain by going to chain drive and some guys will idle back whole machine to be easier on things. A good operator can do these things. Move tins down in hopper and unload near idle. Auger flighting needs to be in good shape in unloading system and I'll sometimes extend flighting on auger in bottom of tank closer to universal joint bushing support area. Wet puffy beans and dirt will give you problems so do what you can to avoid. Edible beans is one of them crops that many have tried and many quit tring. like many crops there is a learning curve. It's seldom as easy as it may look. Good luck

Hey NDDan, you mentioned removing reverse bars to stop grumbling in a N. Does that also work on the small P3s in wheat and soybeansIJ Thanks, Ryan.

Depending on conditions just two reverse bars can hold up flow and cause large amount of grumbling. Some have found they must run reverse bars but we do everything in our power to prevent using them. I've never reinstalled a set I removed. Good luck

Thanks for all the detailed suggestions. We just got the channel helicals today - ouch! Both in price and my elbows are sore from working inside the cage! Part no. 71328026. It sure is slick to take out the cylinder - strange how the neighbors show up as well! Should finish install in am and hope to give them a whirl tomorrow afternoon. All the help greatly appreciated!
