Hedgecutter motor coupler to head

[andybk]

anyone know who will replace/ repair the coupler to head on a hedgercutter motor ?, we have an old twose does a good enough job but coupler is worn and stops as soon as under load , we had it done about 10 years ago but cant find company that did it , they welded a new piece to motor and suppiled a new coupler to fit head , think they were birmingham way iirc
