Forks and drawbar question for Kubota LT2350DT

[Highsmith]

Two questions:

1. How to use the pipes welded into the bucket. I assume I can insert an appropriate material and create forks. Recommendations on max length?
2. I would like to tow my 16' flatbed with the tractor. I need an extension for the drawbar that will allow me to turn without rubbing the tires on the trailer. What are you using for your similar sized tractor? (L2350DT - Kubota).

Thanks.
