Bill Tonkin and Lodwic Jones have cut their ploughs in half so that they can move the rear half independently. They dont bend, as far as I know. The idea came from a continental plough seen at the world at York.
That idea has been about for years Harry and it's not hard to do. Bit of an overkill for vintage and classic though don't you think?
As far as lifting the front leg goes then I only lift it for the very last run. It remains there until after the first run next time out when it is put back to where it rightly belongs until the next finish.
