Estimated Construction Time:4 hours.Directions:Set the chop saw to 65o and cut the 2” square tube to length.Cut the flat and round stock to length.Layout the 1” hole in the flat stock and drill a pilot hole using the 5/32 drill. Complete the hole with the 1” drill.Layout and drill the 5/32” hole in round stock. Layout and drill the 5/8” hole in the square tubing. This is a critical dimension as the hole must match the receiver hitch. You may wish to drill a pilot hole first to insure proper placement. Using a course bench grinder round the edges of the pin and flat stock.Place the welded hitch in a vise and heat the flat stock at the bend until it is red hot. Using a large adjustable wrench or a hammer bend the flat stock as shown in the plan. Be careful not to heat the vise.Place the round stock in a vise and heat the bend. Bend as shown in the plan. Clean up any sharp edges on the project. Test the fit in a hitch and make any needed adjustments.Paint as desired.

I built the project after school using the skills I learned in my Ag Mechanics class. I took 4 days to complete the project. The skills I used were layout of the materials, cutting with a horizontal band saw, precision drilling with the drill press, GMAW welding, and bending steel by heating with an oxy-acetylene torch. I sold the finished project at our agricultural mechanics auction.
