Abstract
Abstract A mower attachment in the nature of a blade-enclosing guard or shield mounted on the housing in underlying relation to the blade. The blade, for maximum cutting efficiency, is positioned in spaced relation below the peripheral wall of the housing. The guard includes multiple laterally spaced parallel rods individually mounted, through mounting brackets, on the front and rear walls of the housing. Each rod is maintained by a single releasable clip with the rods providing multiple straight paths for the guided reception of the grass.
