Combines N5 Concave

Guest
The only advantage I see is if you have crops that need more threshing. I have the 8 bar in my N6 and have never seen the need for anymore concave capacity. I can push my N6 in 200+ corn at 5-6mph and it even shells those little kernals on the tip. Also more bars mean more chances of cob breakage which puts more load in the shoe. My .02 worth, Pete Hinrichsen

If it were up to me we would still have the 7 or 8 bar. The potential for over threshing and or starting a rolling mat of material is to real with the P1 cylinder and 13 bar concave. I've never installed the 13 bar concave but have had some show up. Most all complants I get with rotor loss in the older machines have 13 bar concaves. Usually the loss is because of crop got to rolling and best way to straighten back out and seperate is to install them peg bars onto cage. I'd get yourself a good true concave of original number of crossbar design and you'll be better off in a rotary. I'm sure that is the reason that other color rotarys have so many different designs of concave for various crops. If you do install a 13 bar you will find it rather awkward to adjust from corn to beans for the clearance at rear bar will change very little compared to front when adjusted from outside. You would need to get on the eyebolts at rear of concave if you plan on any large adjustments. I even wish the P3 system used that same old short concave and they could add an identical one to seperator side if they wanted and call it a seperator grate or whatever. I suppose the competition would make fun of the small concave but who really cares as long as it works. Anyway I can't say anything good about a 13 bar in a P1 for our crops and conditions. Take care.

I don't think you can open up the back of a 13 bar to clearance you want for corn without cutting slot in cage. I would go with standard setup. Hardened will likely last a good long time for you and you can likely order the wide spaced wires.
