Abstract

A method of agitating liquid manure in a lagoon involves: identifying a boundary perimeter in a lagoon within which an amphibious vehicle must remain while a liquid manure agitation device mounted on the vehicle agitates liquid manure in the lagoon; selecting an agitation pattern to be applied to the lagoon from a group of at least two agitation patterns; and, operating the amphibious vehicle to travel in the lagoon within the boundary perimeter while the liquid manure agitation device agitates the liquid manure in accordance with the selected agitation pattern. The group of at least two agitation patterns includes: a random pattern whereby the vehicle randomly changes direction of travel when the vehicle reaches the boundary perimeter; or, a sweep pattern whereby the vehicle is driven toward a liquid manure pump immersed in the lagoon to push suspended solids in the liquid manure toward the liquid manure pump.
