Combines R65 corn settingsIJ

Sorry drylander but its the path I would recommend also. The rotor is just so aggressive with all the bars in there it beats the snot of of the cobs. I guess you could tinker with your concave, rotor speed, and seive settings and see what you come up with. I am wanting to do a full hyper machine after harvest or maybe next spring. The removing bars just seemed so much simpler at the moment, that why we tried it first and actually have been quiet satisfied with the job its doing for us.

Ran plenty of corn through mine and thought I did a good job. Opened the concave all the way and ran a corn chaffer.

Open the concave as much as possible to maybe 1" or 1 1_4" or just tighter than "cleanout". Try to get whole or complete cobs out of the discharge. Reducing the amount of cob pieces makes it much easier to get a clean sample. Make sure air is wide open also.

I didnt mean to leave the impression that you cant do a good job with the machine set up from factory. We always have a few more of those small pieces of cobs than we liked so we decided to remove the bars and see how it worked. It did work to help to reduced the cob damage but, alot of reduction of that problem could be dealt with the concave settings also. I just think that the rotor is very aggressive for most situations and we dont need it being that aggressive so we took the bars out.

We tried opening the concave and the bottom sieve more today, but still have a problem with pieces of brokenup cob in the tank. Thinking of removing cylinder bars like you have said, however the dealer says they don't recommend that anymore because of rotor loss. What do you thinkIJ

We have reported success of running steep pitch helicals over the THRESHER side and transitioning or blending them into the regular pitch bars in the sep grate. Adding the helical extention is necessary as well. This moves the crop across and eliminates most of the second pass threshing on the lH side of the grate. This is where the cob gets ground up.. lEvel the crate and set the concave at the same diameter as the largest cob size and move the FRONT of the concave down 2 little marks toward MAX. Also the high wire grate is very important preventing cob brake up. On low wire grates pull every other wire and some have made high wire grates by welding pieces of the removed bars on top ot the remaining wires. This has produced very noticable improvments in corn sample. Varieties and yearly variations give different results keep in mind.
