Combines 87 R50 Need Help

I may sound like a broken record here, but avoiding the second pass threshing helped my machine (R50) more than anything. Hump kit, steep pitched helicals over thresher transitioned into the regular pitch bars, helical extention with triangle kit upper lH side, every other wire removed from thresher and separator grate, no reverse bars, disruptors or chopper blades in lieu of reverse bar bolted in center bolt hole where reverse bars were, cut discharge paddles_extended cyl bars, and 4 discharge paddles - 4 cyl bars in lieu of overy other paddle. Control rotor loss with cylinder bars or concave bars bolted to sep grate bottom as needed. Works for us.

Sorry to butt into your conversation MOR50. Tbran, after reading your comments on your machine on the Hyper Mods section success stories a few questions were sparked. Do you have an e-mail I can correspond with youIJ Mine is roedewaldt@bradley.edu Thanks, Ryan.

sure

Your N5 had many less cross bars in concave. I'm gathering most guys having best luck with less cob breakage by lowering front half of P3 concaves toward MAX. This still allows the threshing to start up front while rear half finishes threshing. The less cross bars close to cylinder bars the better. Removing wear strip just ahead of concave is recommended for food corn and is closer to cylinder bars than concave with it moved toward MAX and wide gap for corn. May want to think about removing strip. Secondly the N5 has a bunch of helicals tring to prevent material from passing over concave a second time. Main problem with the Ns was the helicals were not very aggresive. Now look at your R50 where all of one helical dumps material back on concave and some of the second one thus tbrans plan with steeper pitch helicals to prevent this. Next thing to think about that breaks cobs is all the bars spining on seperator side with only one inch clearance to seperator grate material. N5 never had a seperator grate. Different ways have been used to reduce broken cobs hear. One is replace every other bar with half height bars, another is remove every other bar, another is replace grate with cage material or built up existing wires (every other removed)in grate up closer to cross bars, another is install set of rotor sweeps. Which ever you choose from above will surely help prevent breaking them tender cobs. Now follow tbran on the extended cylinder bars to discharge and every other full length bars along with extending top helical toward bearing plate and you'll need another gear. Hope that didn't confuse you but I wanted to try compare N5 to R50 and point out reasons why cobs can break and the options you have to correct. Don't know of anything hear that will hurt you in soybeans. Good luck

I'm running an 1990 R50(short shoe) w_6-30 Hugger w_ Siscoe modified rotor bars(7_8" spacing). People doubt me when I say I've run 1400-1500 bu_a under good conditions. My biggest problem is the standard 8" feeder rolls won't allow sufficient feeding. When I run less I lose more. From your numbers looks to me like you're running 650-720 bu_a corn. losing more on turns, and cob bits on shoe sounds to me like your accelerator rolls need a look. A standard R50 with off the shelf corn bars should run 1100 bu_a. My brothers want standard to reduce losses.Question is, what are your losses in the fieldIJ My manual says 2 kernals per square foot equals 1 bu_a. Make a form 4 square feet and count kernals. Be sure to distinguish head loss from seperator, from shoe. You asked about cutting out every other vane (raspIJ). Siscoe cuts out every other rasp of small grain bars(in 1990 it was 7_16", now it's 1_2") to get 7_8". The Gleaner dealer in that area is Randy Pigg Sulivan Indiana 812-268-4387. He starts with 0" at the top, 1_2" at the bottom, not the .42" in the manual, 3_4" concave clearance, don't know yet what that is on the number scale. But I do know the 10 recomended in the manual is 1 1_16". Too much gap=rotor loss. The leading edge of the concave bars should be square, 1_8" radius is worn out. Siscoe's customers recieve plaques and premiums from Frito lay. Siscoe can't understand why the want less grain damage. Haven't done the 68" pitch bars in the thresh area yet. I'm sorry I can only tell you what doesn't work for me, I only found this forum last winter.

Forgot to mention I'm hearing the high wire concave is needed to reduce cob breakage. When you get to the point you can't get enough through the feeder housing, the 7 1_4" feeder rolls aren't available for the R50. Your parts man will need to research which R52 parts it takes, mine should know Mon. (Dec 13) The lowen Posi Feed rolls aren't in the Sloan Express catalog yet so I asked him to call. 2 weeks to have them built, then $595 each, plus freight ($21-$26).
