The owners manual is missing. The square part that holds the engine cover on is missing. On 12/20 I attempted to send you pictures but some reason they would not go through. Last week my son tried to send pictures to your service department of what our problem is and have not received anything as of today. Anything you can do will be greatly appreciated.

Great engine
The tractor engine is so beautful just to look at, and starts and runs awsome. Maybe the transport packaging could be better.
