It sounds like the leading edges of your concave crossbars are rounded.... crossbars need to be square in order to retard material and force it to the cleaning shoe thru the concave...look for a radius about the same diameter as a BB...if crossbars are about that roundness, it should be replaced....if cylinder bar teeth are rounded over from front to back and under 1_4" tall, they should also be replaced....Concave not bad to change--does fit tight and needs to come straight out...if newer style, has 2 carriage bolts holding it in back adjusters,,if older style, has shaft all the way thru machine..both styles have shaft thru fron of concave...if running large tires, may find it necessary to pull at least 1 wheel (FYI 9000 series JD are mounted almost identical to a Massey)..........Hope this helps
