HI guys! I got lost! Been very busy with "non-work" related items. that has kept me very distracted! I am curious also. Well more that curious, I am very interested in doing this!. I want to do the mods to our R42. all I got done this summer so far was to pull out every other wire in the grate. Before we got into wheat. I am very curious about modifying the system, but I am one of those guys that needs to see it and feel it with my hands to be able to do something of this nature. the question I have always had with the F bars is does this change the "clearance settings" on the grateIJ Then with our smaller processor, do we remove every other row of barsIJ or leave them all in and replace just the reversersIJ Here around lincoln, NE, most of us think this fall is going to be a drawn out harvest (crops are slow to mature),and the weather is not going to cooperate! Thanks, ps someone; please kick me if I fall a sleep again!
