I am wanting to build a few more tractors.  I have been building them like the Salatin model, but the material is a bit expensive, and they tend to get heavy.  I am wanting to build a "hoop house" style tractor.  I am going to use some treated 2"x8"'s to make the skirt around the bottom, putting some braces in the corners to keep it sturdy.  I then want to make an arch across the width about 5' high, and then cover part of it with chicken wire and a tarp over part of it for shade.  And finally, put a door on one end for access.  The problem I am having is coming up with a material to make my arches.  Has anybody made a tractor like this?  What did you use to make your arches?  Pics would be great as well.
Thanks.
