Combine must be thoroughly cleaned and inspected prior to harvesting Identity Preserved (IP) & Non-GMO crop, even when hiring a custom combine. Combine clean-out procedures are as follows:
-Run the combine, engage the separator and vary the RPM speed.
-Disconnect header.
-Remove crop residue under header auger
-Drive combine up on 6-inch blocks on right hand side. Run unloading auger to empty sump
-Shut down combine, set brake and remove key from ignition. Install feeder house safety locks.
-Remove access shields and open the stone trap.
-Clean feeder house at front corners by drum, lift feeder house chain from floor to allow any trapped grain to run out.
-Cylinder may require a tapping on filter plates to assists in removing build up.
-Clean grain elevator with door open and lower auger panel removed, turn elevator by hand to spill any trapped grain.
-Open tailings elevator door as well as sample door, turn elevator by hand to removed trapped grain.
-Sieves, chaffer and pre cleaners can be removed for cleaning. Clean area by blowing or vacuuming. Clean grain bin from right to left towards the sump; remove sump covers to allow grain flow out.
-Blow or vacuum the fan area to allow the removal of any trapped grain.3
-Growers should harvest 200 feet of crop and deliver as commercial product (Flush)

NOTES:

-Growers should endeavor to harvest their IP/non-GMO crop before the combine is used on other crops.
-Equipment used to transfer soybeans must be thoroughly cleaned and inspected prior to transferring IP/non-GMO crops. This is to be done regardless if grower uses their equipment or hires custom equipment.
-It is critical that all grain and meal residue is cleaned from the inside of the truck. Ideally the truck/hopper should be covered.
-Grower must keep detailed records of cleaning procedures, and inspect truck. By signing the Bill of Lading, the driver and grower acknowledges this procedure is being followed.
