Combines A Question for Rolf

[Bert]

I have heard of two guys in my area doing the same thing, but never found out why. I would also like to know.

High Bert, Are these guys who have also went from the high low style rotor back to a standard oneIJ If so, I would be interested in speaking with them about it. I want to research every perspective before I decide what might work best in my situation If you here anything, let my know.Thanks Bert, DAB

G'Day Fellers We actually had a High_Standard type of set up on the sep end of the rotor!!! We had every second Forward rasp bar raised by a 8 mm thick flat strip of steel under each rasp bar on the full length of the sep end! the thought was to help not grind everything up with our tinder dry crops and to see if it would help a bit with lowing rotor loss!!! Welllllll!!!! we came to the conclusion that we were better off having a constant thickness of fast layer of material running round than having some areas with a thicker_thinner layer!!! now maybe we should have gone to all of the rasp bars shimmed out but we have a stationary rasp bar in the bottom of the sep cover grate which only has a couple of mm space with the high spaced rasps, so that was another reason that we have taken the 8mm shims out!!! This year I have taken out every second rod from both the lower and upper concave's and so far with only about 80 meters of slightly green wheat I don't think there with be a problem with thrashing!!! I have also closed up the front of the concave to about 3 mm with the top back just touching the highest bar. (This is with a low rod narrowed spaced wire concave!!! I now have about a 40 mm gap between rod's! I say you should be able to take ever second rod out of the N series concave and have know worries!!!!!) I would Highly recommend that you put the Channel helical in a N series as this with help a lot with smoothness and performance!!! (wish I had know about the Channel helical's when we had the N7!) One mod we did to the N7 was put a 2-3mm thick flat strip 20 to 30 mm wide under the standard helical's that hang out on the discharge side of the helical's to give the effect of half a channel heical! (Cheap to do and easy to make!!) Thanks goes to John Ryan for that one!!!! We have also made a Copper bar that goes in were the peg bar is meant to go this is made up of sickle sections that have been cut in half and bolted to a bar that can be inserted 10 or 20 mm in or out through the cage! this is supposed to help with rotor loss and hopefully not use very much HP!!!!! Now I have also installed Stainless steel Acc Rollers this year and went to great pains to find out why they were not inter meshing as much as a new set of rubber ones!!!! Well I have been Assured buy AG-WARE in Gunnerdar (Thanks Peter Jones) ,that most of the guy's that have the SS Acc rollers say that they work fine and all of them have never replaced them since installing them, and they even get them installed when they buy a New Header!!! (That has to say something!!) Anyway that long winded enough for me!!!! Give us a yell if I have not explained it enough!! Rolf

No I heard that they just didn't feel the hi-lo setup worked. They had other mods done but I don't what they are.

HI Rolf, Thanks for the info! I have both thresher and seperator helicals double stacked and I wondered in the high low setup might relieve some pressure on the seperator side. I would like to try the the modified cylinder, or even shrink the seperator side and leave the high low bar idea out. I just don't really want to set it up that way and then change it back because it didn't do what I wanted it to.Thanks again,Darin
