Has any one put the S series discharge beater vanes in a 50,60 or 70 series STS? On my 9770 the right vane is maxed out as far as it will go to the left and still needs to be moved more. Noticed deere has changed the design and put them on the back wall of the chopper housing. Still trying to get the straw and chaff to enter the chopper evenly so the power cast doesn't force it all to one side. TIA
