Thanks guys.
Today, I picked up some 1/2" black pipe and cut some pieces to weld to the bottom edges of the deck to reinforce it. I decided to add a piece along the back too to help add reinforcement for the gauge wheel mounts and to make it match the front.
I introduced the deck to my sledge hammer and gave it a little "attitude adjustment" to get the front side back in line. It is now straight and ready to weld the pipe on.
