On your 930f, which holes are your rear strippers and floor strippers located???with header attached, the rear strippers should be even with the opening of the feederhouse, not extending in to the feederhouse , not short of the opening either, there are three locations , should be the middle hole. How is the auger
?at each end of the platform the auger should be 1/2"off the floor and the auger should be as close to the feederhouse weather shield as possible, make sure if you do any auger adjustments do them locked up with header fully raised, also double check auger finger timing, 5/8" from end of finger to the largest carriage bolt head.Move your top adjustment for auger drum to the 12 o'clock setting , you will never need to move this adjustment again, do all your adjustment with lower bolt, make sur the eccentric is below lower adjustment bolt , this will be your grain setting.Now about the feed ramp, all 00-02 have what deere calls tri stream feeding, 03-to present have actually four streams of feeding , deere only advertises three. This change was made for more even feeding
and more capacity, I recently replaced most of the ramp on a 02 9650sts do to rock damage.Also never install spacers to the left side of seperator grates in small grains, good way to tear out a discharge housing.I believe you have a 930f that never got the auger adjusted properly from new and along with the drum in the feederhouse its not getting to the rotor properly.
