I'm contemplating buying a 963 and putting a dozer blade on it for terrace work. Leaning towards a 963C because 963D's are mainly out of my price range and the few 963B's I have seen in my area have a ton of hours on them. Basically trying to figure out what blade would be a good match for this machine. I used to have a 977L that had a straight blade off of a D6C on it and it seemed small for that machine. I have seen quite a few 977's that fitted with old D7 straight blades that seemed to be a better match. Any input would be greatly appreciated.
