Check out this Sulky I make from scrap metal lying around the shop! (including the wheel and diamond decking!) I'm into it $.79 (for the new farm pin clip), and some time (about a day). I just used some channel, angle, plating, and square tube. The bearing was a part of an old sod cutter. The Mower already had a sulky mount bolted on the frame so I didn't have to fab that! It works really well! I think I'll shorten it a little bit because the front frame where my toes go hits curbs and walks and whatever is on the edges when I'm trying to turn inside a corner.
