I tried looking back through old posts and couldn't find the instructions on doing that. Could someone provide a narrative in zeroing_leveling the concaves that I could print offIJ

I am new to the rotary crowd and will be doing over 700 acres of corn here in a couple of days and would like to know of this too.

Redgreenshow and West illini, It took me awhile but I found the instructions for zeroing concaves. Good luck No special tools are needed. With the middle concave removed, raise the concaves and at the same time turn the rotor by hand. When the first rotor bar makes contact with the concaves you have zero. Adjust the front and the back to make contact at the same time with that 1_2 draw bolt on the front concave. Then lower the concaves about one turn and set the gage to zero. Also the rotor bars should make first contact with number seven and eight concave bars counting down from where the top and bottom concaves are bolted together. And that is why you need the middle concave removed so you can look in there and see where the rotor bars are hitting the concaves. If the rotor bars are not hitting number seven and eight concave bars first the concave can be adjusted from left to right on the right side of the rotor cage. Remove the front shield on the right side of the combine and loosen the five bolts on the front and the back wall of the rotor cage. Then adjust the front and back 1_2 draw bolts to move the concave either to the left or to the right so the rotor bars will hit the seven and eight concave bars first. Sounds complicated but it's a piece of cake. Good luck! Brad NC. IN.

Thanks Abunch! Now that's service!. I made 2 hardcopies to put in a couple different combine books. Now my questin is: How does this 6'2, 230 pound man get in the right side to loosen up the bolts to be able to shift itIJ Maybe I won't have to, if I'm lucky.

I also have 30.5's, but with spacers. So you got me there, I'd probably take the wheel off for easy access.
