Thread: drawbar coupling

If its only going to pull 900 kg that coupling is probably fine as long as it isnt rusty inside.

And for your info the welding on a trailer under 2.5 ton doesn't have to be certified. It just has to be 'up to a reasonable visible standard'

I normally just make a longer plate with the bolt hole pattern for the coupling. Weld the plate to the drawbar. If you didn't want to bust the galv on your existing drawbar you could do plates at 90 degrees to the top plate and pick up those existing bolt holes and bolt it on.
