Is that a tractor wheel weight in the middle of it?!! ballast to stop it rolling over?
Yes it is an old wheel weight. Previously it was a single axle, two wheel setup, and that helped to lower centre of gravity. When it was modified to four wheels, just left it on. Probably doesn't need it now.
This looks a very nice setup. How did it stand the test of time? I have an old homemade single axle trailer with pelletter mounted over a 200kg load bay, but I am fed up with having to reweld it due to it bouncing up and down on the one axle. I had thought a tandem axle would be good and like your design, so am pleased to see yours. Can you please explain what the wheel assembly mounting detail is for? It almost looks like it allows for the rear wheels to steer? I have considered putting the trailer wheels at different wheel centres to each other, though still on a tandem axle, possibly with one wheel mounted on the inside of the tandem beam and one on the outside, with both outside the quad wheel tracks to spread the run down soil to avoid rutting. It might make it a bit wide though. I remember the Overum Tive 6m Suffolk coulter seed drill of the 1980s had 4 wheels with the rear 2 set inside the front outer 2, so it should pull straight.
