Had an hour or so on the zig-zag, found some junk metal in the pile and started making the drawbar thingy, bit of tube a bit of box section and a couple of gate hinges. Still thinking how i can lift it off the ground for traveling.
The chains might be a bit long but i can always shorten them.
Next bit is the hitch end to do then once its attached to the tractor i can work out how to lift the back with the lift handle
