Combines back to ulitmate 12 row monster

Elwood,depends on if this is strictly a what if plan and we are talking only comparisons with the size of the other machines or if you are toying with building such a machine..So here are my thoughts on the subject.Sure you can squeeze more material through the 80 size rotor with more power behind it as we know from the 40 to 60 capacity differences but would suspect that in reality you would need to install the long wear stainless components as it sounds like pushing a lot of crop into the same space really accelerates wear .Also much more power would need driveline beefing up which would be more complicated so if you are building strictly a corn machine how about increasing efficiency for that crop first .lets put in the modified rotor from St.Johns welding with the full set of rear theshing bars which should get us about a 25% increase in threshing capacity with no other changes.Definately keystock grates and maybe disrupters for added turbulance and then run the rotor a bit faster and a bit more open allow more room for flow but not at the sacrifice of quality,which should work out as the machine would be full and threshing enhanced by grain against grain action.would want to be very particular here so as to minimize the amount of mog that the cleaning components would need to do. Sounds like the airjet seives may be the way to go as well but with the increase in material would want plenty of air going into such a system so would want plenty of fan which for me would be the old paddle fan with hilco and baffle from Future Farming Solutions. Now better build one of those self propelled grain buggies to keep grain away from such a machine rather than put so much more weight on the frame and driveline with huge bin extensions and let her roll.

Thank you ohio steve for your input. need more data on St. Johns welding theshing components. I understand about grain tank capicities, no whopper hopper( to hard on final drives) maybe 12" extensions. My beefing up drive idea! use older style 1680 pto set-up, no clutches to burn up just use a hyd. cylinder against the belt... not three strand up update to a four strand. use the lated rotor belt from case. use a synthetic oil in the feeder gear case instead of 90n it will run alot cooler. yea feeder gear box to feeder will need to be heavier, maybe four strand belt instead of three and the same for header drive off of feeeder. scrap the old three groove pressed steel sheave and get a four groove taper lock set-up....who every invented the gib keyIJ they should be shot! I think we're getting there

I've Seen a experimental labeled CX100 Big floater size tires up front,Grain tank was removed and replaced with bigger engine 450hp rear axle was gone and replaced with articulated hitch that connected to 600bu grain cart on trackes twin augers moved clean grain from where engine was to grain cart in rear. Did anything ever become of it, this was in 1997

Say, Ohio Steve. Why would you want a modified paddle fan for more air instead of the newer style squirrel cage typeIJ Just curious

I spoke with Phil at Future Farming Solutions prior to ordering one of their air deflectors for my axial flow and he told me that their research in determining the correct setting for the deflector also led him to think that the old style paddle fan could push more air at high rpm's.The problem is that at high flows the center of the fan starts to starve for enough volume so that was why I mentioned the Hilco fan conversion .The new crossflow fans by taking air evenly across don't have the center starving but but are harder to get more air out of at the top limits. I really like the air deflector in my machine but it takes more air volume to get the best results . Some on this sight have not had as good of report and had problems with grain getting into the fan housing with the cross flow fan so since this 12 row machine will have a heavy load running through the cleaning system the old paddle fan seemed to make sense.Just an opinion which is open for discussion and always enjoy others experiences and have learned some new tricks along the way..But increasing air flow to the back of the sieve area reduces tailings dramatically and also gives a sample with less mog that can be blown out( white caps red dog soy pods and such)..

I think I would lean toward the old style fan with the Hilco kit also. We have the crossflow maxed out all the time, and it does a fine job, but I suspect we could use even more air volume at times. For our machine the fan deflector is by far the best mod we've done.
