Abstract
A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of blades in a blade channel. The blade assembly is covered by a blade assembly guard that is only open underneath at a point where blades in the blade assembly would cut grass during normal operation. A blade assembly access panel in the upper portion of the blade assembly guard allows blades or a blade assembly to be easily replaced.
