Commercial lawn mower outlet cover

1 . A commercial lawn mower deck combined with an outlet cover for covering a grass outlet opening to permit mulching of grass and/or leaves; the outlet cover comprising:

a cover plate being rectangular and having a length and width sufficient to cover the grass outlet opening in the deck of a commercial lawn mower;

a bracket structure being configured to removably connect said cover plate to a deck flange positioned above the grass outlet opening and projecting vertically from the deck of the commercial lawn mower;

said bracket structure being L-shaped and comprising a plate portion having a height and a length sufficient to cover a substantial portion of the deck flange;

said bracket structure comprising a connecting leg disposed essentially perpendicular to both of said plate portion and said cover plate; and to connect both;

said connecting leg having a width sufficient to space said cover plate and said plate portion apart from one another to create a receiving space sufficient to receive the deck flange therein;

said connecting leg is configured and disposed to rest on a top edge of the deck flange upon installation;

said bracket structure having a length such that sides of said bracket structure are positioned close or immediately adjacent to a pair of discharge chute mounting posts behind the deck flange and projecting vertically from the deck of the commercial lawn mower such that the discharge chute mounting posts resist sliding movement of the commercial lawn mower outlet cover on the deck flange;

said height of said bracket structure being sufficient to maintain engagement with the deck flange upon unintentional slight or moderate vertical displacement of the commercial lawn mower outlet cover by impact with outdoor objects or jostling due to vibrational forces; and

said bracket structure is configured and disposed to freely suspend said cover plate from the deck flange such that said cover plate is easily lowered or dropped downwardly into a blocking position to cover the grass outlet opening to permit mulching of grass and/or leaves and is easily lifted upwardly and off of the deck flange to permit ejecting of cut grass and/or leaves out of the grass outlet opening.

2 . The commercial lawn mower outlet cover of claim 1 , wherein:

said bracket structure comprises a first bracket structure;

the commercial lawn mower outlet cover further comprises a second bracket structure configured similar to said first bracket structure;

said second bracket structure is disposed adjacent and spaced apart from said first bracket structure to form a guide slot therebetween;

said guide slot is configured to be slid around one of the pair of discharge chute mounting posts to guide and properly position the commercial lawn mower outlet cover during installation and further resist sliding movement on the deck flange.

3 . The commercial lawn mower outlet cover of claim 2 , wherein said cover plate comprises metal or heavy-duty plastic of sufficient weight to further resist unintentional vertical displacement of said cover plate.

4 . The commercial lawn mower outlet cover of claim 3 , wherein said first bracket structure, said second bracket structure, and said cover plate are integrally formed from a single metal piece.

5 . The commercial lawn mower outlet cover of claim 4 , wherein said cover plate comprises rounded corners at a lower portion thereof to minimize impacts with a ground surface or structure during a mowing procedure to further resist unintentional vertical displacement of said cover plate.

6 . The commercial lawn mower outlet cover of claim 5 , further comprising a handle disposed to project from an upper portion of said cover plate or said first bracket structure to provide easy and safe lowering and lifting of the commercial lawn mower outlet cover.

7 . The commercial lawn mower outlet cover of claim 2 , wherein said first bracket structure, said second bracket structure, and said cover plate are integrally formed from a single metal piece.

8 . The commercial lawn mower outlet cover of claim 1 , wherein said bracket structure and said cover plate are integrally formed from a single metal piece.

9 . The commercial lawn mower outlet cover of claim 1 , further comprising a handle disposed to project from an upper portion of said cover plate or said bracket structure to provide easy and safe lowering and lifting of the commercial lawn mower outlet cover.

10 . A method of quickly covering and uncovering a grass outlet opening of a commercial lawn mower using the combined commercial lawn mower deck and outlet cover of claim 1 comprising the steps of:

lowering said cover plate and sliding said bracket structure onto the vertically-oriented deck flange of the commercial lawn mower;

moving said cover plate into a blocking position to cover the grass outlet opening;

operating the commercial lawn mower and cutting grass and/or leaves and then mulching cut grass and/or leaves within the deck;

lifting said cover plate upwardly and off of the deck flange and uncovering the grass outlet opening;

operating the commercial lawn mower and cutting grass and/or leaves and then ejecting cut grass and/or leaves out through the grass outlet opening; and

repeating the above steps as desired to perform mulching or ejecting of cut grass and/or leaves.
