Abstract
Abstract A rotary lawn mower comprising a deck housing supported by wheels for movement along the ground. A motor is supported upon the deck housing and drives rotary blade means disposed therebeneath. An upstanding handle is connected to the deck housing for control and manipulation of the mower. The handle is pivotally mounted upon the deck of flipover movement to facilitate opposite directional, longitudinal movement of the mower without having to turn it around. Novel guard means is provided on the mower to prevent an operator''s foot from accidentally coming into contact with the rotary blade means. The guard means is constructed to so protect the operator''s feet in both longitudinal directions of movement of the mower, and to minimize interference with efficient grass cutting.
