          | I have the opportunity to purchase an older AC grader but cannot figure out much about it. This machine runs great and functions nicely. Can someone help tell what year and model it is based on the serial number   |

          | It sure looks like a DD model but may be a model '65' something. The serial number book doesn't cover the 73L series but by judging numbers somewhat close, it it's likely a more late model, when they made them, rather than older. Regardless, it's a very clean looking unit. It may have possibly been well maintained seeing they spent the money on good tires??  What is the asking price?

          | I agree, looks like a DD, but the square frame says its a late model, and the rear scarifier may indicate a later model, too.  Might also be something someone put together out of 2 or more. Tin seems to indicate an early model...

          | The ripper assembly was an add on that someone put on it. They want $12000.00 for it, seems a bit high to me. |

          | I would guess a DD. Square frame and diesel engine. Well equipped with most of the options.
