3/8" should be sufficient, but I wouldn't go any smaller. I went with the 1/2" for the strength and because they had a piece of 1/2" x 4 in their drop pile. I would definately go with 1/2" on the hook ups for the lift arms. I think 3/8" might bend there. 2 planters with the toolbar will probably weight around 400#. add in 2 bags of corn and you have about 500#.
Also, you need to measure your u bolts. John Deere planter toolbars are actually 2 1/4". I had to do some pretty significant grinding last night on the 2 1/2" to mount the planters. I would try to go with 2 1/2" bar and not tubing. If I had used tubing I would have ground almost through the wall of the tubing to get the bar small enough to mount the planters.
The planters are on the toolbar and mounted to the tractor. I plan to plant about 2 acres of Indian Corn and 1 -1 1/2 acres of white field corn when I get home today.

Chris, I decided to go with 1/2" x 3" and 1/2" x 6" for the hook up bars. I have over 36 feet of 2-1/4" diamond tool bar cut from the old JD 184 fertilizer unit I am taking apart so I am good there. My planters will weigh a little more that yours because I have the front packer wheels.
