1. A method of agitating liquid manure in a liquid manure lagoon, the method comprising:
identifying a route in a bounded operational area of the liquid manure lagoon within which an amphibious vehicle uses a liquid manure agitation device mounted on the amphibious vehicle to agitate the liquid manure in the liquid manure lagoon; and
autonomously operating the amphibious vehicle to travel along the route in the bounded operational area of the liquid manure lagoon while the liquid manure agitation device agitates the liquid manure in the liquid manure lagoon using a propeller having a thrust vector that is configured to be directed vertically upward toward a surface of the liquid manure lagoon to cause agitation at the surface.
