Combines N5 Pacer

don't feel like the lone stranger. The little meter is an indcation of voltage generated by objects contacting the pacer boards. One on each side of the shoe and one in the processor compartment at the discharge end of the cage accessable through the grain bin inspection panel next to the unloader side. Now this signal is modified by the ground speed sensor, the range setting, and the set point. The range is the sensitivity. n2 is the most sensitive for crops like small seeds or oats maybe wheat. The next setting is 4 and is for larger grains such as corn. I don't know what the other two are for maybe those rocks I get in the great northern beans every once in a while But the farther you turn the knob clicks clockwise the lESS sensitive the impulses to the meter are. Now there is the set point. One uses this to set the needle in the green range ONCE THE COMBINE HAS BEEN SET TO ACCEPTABlE OPERATION. Now keep this in mind. As you start out at very slow speed and say the board receives 10 hits per minute then the ground speed increases to double and the hits go to 20 per minute, the system is designed to keep the needle at the same reading because the loss _ A is the same. If you speed up suddenly the needle will go green as it takes a few seconds to calibrate. Conversely when the needle sez 'slow down' it will read even more in the red as you slow down till it again calibrates. When I go to the field I use the pacer to fine tune the combine. First set it by the book, it is good. If possible I set the range at frist to 2 or 4, the set point to 10, and start harvesting. If the needle pegs to slow I switch the cyl _ shoe switch to see where the loss is coming from. If it reads loss shoe, I first up the air one round at a time and watch the results. Usually loss is due to not enough air rather than too much. If the loss does happen to get worse then lower to start point them lower one round at a time to get best results. If this remains unsatisfactory then stop and increase the top screen opening and start process again. Then using the cyl. side watch the needle to set RPM to minimize loss. Keep in mind concave setting is very critical. Too wide and one does more threshing in the sep. side, thus less time for separation. Finally the toughest thing is to determine in the sep._cyl loss mode is it grain hitting the board or are sticks _ straw making the needle jump. This can only be determined by checking loss per the op man and adjust set point accordingly. Some good operators we have will run on 'shoe' after setting machine and periodically check cyl loss via pacer even though needle will not run in the green when left on total or cyl. due to dry brittle staw etc getting to board from cyl.. Hope that is not too much too fast. whew.... finally harvest loss rates are usually lowest at capacity. It is tough getting a new operator to push the machine to near max capacity; neighbors hate those sonic booms....

Thanks man! I think you have helped me solve the only mystery left about my N5. Scott
