G'Day Kurt Tom might post some pictures that i sent to him of the Posifeed rollers on the upgrade site sometime!! Farmer friend (Steven Schulz) that lives 40 k's away developed them for his Case 1640 as he was having feeding troubles (seems like they all do!!!!) anyway he Modified his feed drum so as to have a triangle tube with round rings were the feed chains run, now he has a manufacture making them for him and they are now under patent pending, There has been some "Copies" been made by a couple of dealers over here which has caused some 'problems'!!!! but Steven Schulz is the inventor. We ended up putting two in to ours as 1, nobody had done that, and 2, only made common sense for us to put two in to our R62, It has really made a difference in barley as that would repeat around the table auger, still doses a bit but at 12 kms_hr max. Im not to worried about it and I think I need to make the rear posifeed roller run a bit closer to the front feed sprockets so as to grab the material coming up the feeder house, ND Dans idea of opening up the throat some at the back sounds like a bloody good idea to me as we are starting to get a lot marital stuffed up that feeder now with all our hyper ideas, and anything to help is what is needed!! Now! I reckon if all us Gleaner pilot's were talking about a different colour we still be making them out perform the standard machine!!!! IMO Rolf
