Wheel Nut:
Notice the lack of landing legs on the latest picture in my post!They were not designed for quick trailer swaps but would stay together like a Shawnee Pool or a Moxy. In fact looking at them I can see where his idea came from now. The SP trailer put the drawbar weight through the tractor wheels and the early Moxy had hydraulic drive on the trailer wheels.
Malc, I remember the Shawnee pools, Ford tractors and single axle trailers, were they designed by David Brown?
I remember a company from Cardiff off Newport Rd and Rover Way called Steel-Fab. They were the main supplier of front end loader and backhoe attachments for Ford Tractors.
They also had a system called the Power X which was a trailer/ skip system pulled around factories by tractors. The early Telehoist skip system was a modification of the Power X system.
I only saw one Multi- Drive and that was a TM, it looked impressive, but probably needed the right drivers behind the steering wheel!
