I'm trying to find the name of a short story with a Bolo that was converted to a farm tractor. Its world is invaded by aliens and not having weapons it has to adapt its farming tools to fight back.
Also, what Bolo book is that in?
It could be 'The Farmers Wife' pubished in 'The Triumphant'. In this story the Bolo 'Digger' is left on a planet when the colonists leave due to the approach of hostile aliens. Digger is left behind and combats the 'Agricultural Pests' using bio-warfare techniques.
