Wooden Farm Toys for Haymaking

Step 13 The hitch in detail

 The drawbar needs a hitch to attach to the tractor's drawbar hitch.  I attached a flat piece of steel to the underside of the aluminum rod.  Notice the right end in the photo.  I ground it down to make a round pin and then bent the pin upward so it can fit into a recessed hole in the round rod.  The red lines indicate the portion hidden inside the hole.  A screw attaches the flat piece to the round rod, but I damaged the threads with a cold chisel so the nut cannot turn or loosen.  See the azure blue arrow.
