northern chester county PA | It wont cost much to get the 2 shafts for the chain coupler style . I would need to go look if they are a hex shaft all the way to the bearing and pulley on the left and the sprocket on the right . If they are it , would be very easy to do . Also be a where that for a older combine on a 900 series head there is a larger pulley available to drive the knife . The dial-a-matic will work with the correct adapter . 9 pin to 16 ? . Dont remember |
