Mentioned this a long time ago! Rolf came up with this. Check that the speed that the header auger sweeps the material across the front is faster than the ground speed. Auger pitch times the RPM gives the auger sweep speed. Our 94, 500 series flex header auger had the wrong sprocket and was running far too slow. Speeding it up so that the sweep speed exceeded the ground speed made a big difference. It helps to stop bunching in front of the auger. A question to Dan, tbran and all the other very innovative Gleaner gurus out there; Has anybody ever experimented with different auger pitches on the header augerIJ Reason for the question; In the N7 parts book there was a 24 inch pitch flighting available for the N series specifically for Australia. I know of only one N7 that was equipped with this 24 inch pitch as compared to the usual 30 inch pitch. This machine, according to the then owners, never ever had feeding problems whereas all other N's used to regularly have feeding and plugging problems. In an effort to improve feeding, we installed a second lot of flighting on our N7 header midway between the original flighting with some improvement in feeding but not significant. Auger pitch on the current model headers is 27 inches. Perhaps a faster turning 24 inch pitch may operate better as the angle that the leading edge of the auger meets the crop would be in a more vertical position. On the N7, when the heads of a crop were leaning towards the centre, that side fed very well whereas leaning away from the centre plugged regularly, so I made a set of very light crop lifters out of 3_8 rod that were bent towards the centre and tilted the crop heads toward the centre as it was cut. This made a huge difference to the feeding on the N7 header, particularly if the crop had a lean on it. The 500 series header on our R62 feeds a lot better but still needed a lot of work to get the best we could out of it. We may not even pull the combine into the paddocks this year as we have just had up to 36C [ flowering stage of the cereals! ] and down to one percent [ 1% ] humidity, so low that the meteorologists have no records of it happening before. It was also the hottest October day in 90 years in S.E. Australia. Around 200 fires started today in Victoria today with about 8 major ones still going. Wind speeds were around the 45 kph [ 30 mph ] gusting to 85 kph [ over 50mph ]. A very bad day! This on top of only about 7 inches of rain in our area for the year so far. Australia may not have enough wheat or barley to export this year so you guys else where in the world should really be looking at some very good prices. As it is the world will consume at least 51 million tonnes more grain than will be produced this year and world stocks are running down fast. Good luck! I just hope our turn comes very soon.
