Couldn't access your email, but I can describe how I built it. Mine is 13 feet wide, pulled behind a JD8300 drill. Took about 15-17 tires, I think. First- find your tires! Trucking companies may give them away, then they don't need to pay a disposal fee. All the same rim size- 20, 22.5, or 24. Measure the width of the tire and decide how many you need to cover the width of your drill. I found 20 inch gas pipe at an industrial salvage yard. Since the tires I used were 22.5, I welded 4 lengths of half-inch diameter pipe lengthwise along the gas pipe, at 12, 3, 6, and 9 oclock. That creates a 'new' diameter of about 22 inches. I had scrap plate steel, half inch thick that I used for end 'cookies'. Two on each end, spaced about two feet apart. Cut half-moons in the inside ones so water can flow from one section to another. Weld two pipe couplers for filling and draining. Weld solid shaft from the inner one, through the outer one, where the hitch bearing is mounted. I found 2 1/2 inch bearings and shafts in a salvage yard for $25. On one end I welded 2x2 angle in an 'X' pattern, extending past the cookie edge, to hold the end tire in place. Opposite end I did the same pattern, but welded bolts on the cookie, so the 'X' can be bolted on after the last tire is slid into place. Tow hitch is made from four inch square tubing. You do not want a single continous shaft through the assembly for an axle. It tends to break. Use separate shafts on each side of the unit. Hopefully I can post a picture here later- I usually have difficulty doing that.
