Have a 12m Evans and Pearce broadcaster at home that has been retired from slug duties in place of a new bullock tillage unit, was looking at trying to use the old e&p spinner to put ground feed out for pheasants so need to slow the disc down, would a standard fan controller type thing work like this?
