84 gleaner n6 mods

I can help you a lot. "Hyperizing" isn't always the best way to go. Questions for you, because your answers dictate what would be the best way to change your combine. #1. Have you ever used this combine?? like you've just bought it and think you right away need to change everything there is ???  #2. What crops do you plan to harvest ???   #3. Are you all flat land or gently rolling hills or extreme hills ??  #4. How capable are you when it comes to fabrication and welding/repairs ?? #5. Do you have a forklift to remove the rotor ??   #6. Do you have any idea what has been done to the processor when it comes to concave/rock door/helical bars ???  #7. What are your performance expectations??   I have seen some combines ruined from too many unwarranted modifications. What works in one area/one crop doesn't always work somewhere else. This will be a good start.

If I was prepping a new 1984 N-series for corn/soybeans only, the following was done before it left the shop: #1. the rotor was pulled and two factory reverse bars were removed. #2. every other wire in the rear three rows of the concave were cut out with a torch. Short remaining wires were tack welded so they could not move. #3. the four helical bars on the dead bottom of the separator cage were removed. Then, a flat 3/8" thick by 1 inch wide crop bar was installed at 6 o'clock dead bottom of the cage. This flat bar tumbled the fodder to shake loose any trapped kernels so they would separate out thru the cage. #4. two extra rows of long helical bars over the top of the rear feed chain were installed (total of 4 extra bars) for constant crop transition under tough conditions. One or two short thresher helical were added in at the half-way point in the cage (with fabricated fasteners) to keep crop from going around the concave a second time. This is pretty important.  #5. a 3 inch tall wall about 12 to 15 inches long was welded to the front of the tailings auger trough to move over to the left any tailings return and to help move some % of grain more to the center of the machine due to the concave being more "open" with wires removed. This was a big help in steep side hills when leaning to the right.  6. On N-5 machines a cage cover was installed above the discharge paddles to keep loose grain from falling back into the cage and going out the straw chute. Keep 1 inch away from the cage and on top of the hoops. 12 o'clock down to 10 o'clock is enough coverage #7. Rotor RPM's were kept around 240-260 in corn and under 600 in soybeans. My rotor losses in corn were NEVER over 1 BPA and generally always less than .5 BPA.   #8. 1 5/8" long tooth square tip corn chaffer is a MUST with the front 8 rows independent of the rest of the chaffer. Run the front 8 rows a little wider than the rest. This was my "hyperizing" from 1982 thru the end of the P-1 processors in 1991.   Every new machine got this done to it. Every older customer machine eventually got these same things done. That's why we sold combines and had happy customers.  2000 to 2200 BPH in corn was max capacity in an N-6 or 7. With a 6-row corn head in 140-150 BPA corn it was usually as fast as 2nd gear would go...5.5 MPH all day long AND machine losses very very low.
