 SESD | Use steel I beams of choice. Make a "bumper" on front and back out of channel iron, like 6or8", and bevel the bottom of the beams the last couple feet to match the width of the channel. Run a few angle iron between the bottom of the beams and space them out the length of the beams to keep the beams at the right width. For a "rack" on the back, we've done it 2 ways. 1-weld a channel(6-8") on each beam vertically(have some angle to help with loading so the front is stepped and tall enough for 5 or 6 layers) and attach pipe or tube for the cross bars to support the bales as well as an angle iron vertically on the outside of those cross bars to tie them together. 2-weld 1 size bigger channel(short enough to be below top of bed) to beams and slide the "rack" into them and bolt together. This allows you to remove the back rack if you ever need to hang something out the back.
For the bed, use bridgeplank. space about 2". On the outside of the bridge plank, bolt a "c" iron or angle or something to tie them all together. Depending on the length of the plank, you should be able to get 2 planks out of each. If they aren't long enough to make a 9' bed, make more of a rail like on trailers to get the extra few inches of width on each side. | |
