Good machine or no?? Pros....cons???
Maybe. What are you proposing to do with it..?
I can't think of a single bad thing to say about a D9G, especially a late model one. One of the best dozers ever built. They were used hard and abused though because they were so tough, so make a very careful inspection before purchasing. I have seen some very sad examples at auctions.
+1. Because there was nothing wrong with the old D9Gs or D9Hs.
