a spindle extending from the cutting deck, the spindle configured to support a cutting blade for rotation relative to the cutting deck;

a spindle housing mounted to the cutting deck and surrounding the spindle; and

a mounting member coupled to the spindle housing, the mounting member configured to support the mulching insert within the cutting deck,

wherein the spindle housing includes a distal end that is spaced apart from the cutting deck, and wherein the mounting member is coupled to the distal end of the spindle housing,

wherein the mounting member includes a body portion and a flange, the body portion engaging the spindle housing, the flange extending from the body portion and radially outwardly from the spindle housing to engage the mulching insert,

wherein the spindle housing and the mounting member are fixed relative to the cutting deck.

2. The system of claim 1 , wherein the mounting member is configured to capture the mulching insert between the flange and an inner surface of the cutting deck.

3. The system of claim 1 , wherein the mounting member is threaded onto the distal end of the spindle housing.

4. The system of claim 3 , wherein the spindle housing includes an outer surface and threads formed in the outer surface, and wherein the mounting member threadably engages the threads of the spindle housing.

5. The system of claim 1 , further comprising a bearing positioned between the spindle and the spindle housing.

6. The system of claim 5 , wherein an inner race of the bearing contacts the spindle and an outer race of the bearing contacts the spindle housing.

7. The system of claim 1 , wherein the mounting member is removable from the spindle housing to allow removal of the mulching insert from the cutting deck.

8. The system of claim 1 , further comprising:

a plurality of said spindles extending from the cutting deck, each spindle configured to support a cutting blade for rotation relative to the cutting deck;

a plurality of said spindle housings mounted to the cutting deck, each spindle housing surrounding one of the plurality of spindles; and

a plurality of said mounting members, each mounting member coupled to one of the plurality of spindle housings and configured to support the mulching insert within the cutting deck.

9. The system of claim 1 , wherein the flange includes an upwardly facing surface, and wherein the flange is configured to support the mulching insert on the upwardly facing surface.

10. A lawn mower comprising:

a frame;

a plurality of wheels coupled to the frame;

a cutting deck supported by the frame;

a mulching insert received in the cutting deck;

a spindle extending from the cutting deck, the spindle configured to support a cutting blade for rotation relative to the cutting deck;

a spindle housing mounted to the cutting deck and surrounding the spindle; and

a mounting member coupled to the spindle housing to support the mulching insert within the cutting deck,

wherein the spindle housing includes a distal end that is spaced apart from the cutting deck, and wherein the mounting member is threaded onto the distal end of the spindle housing,

wherein the mounting member includes a body portion and a flange, the body portion engaging the spindle housing, the flange extending from the body portion and radially outwardly from the spindle housing to engage the mulching insert,

wherein the spindle housing and the mounting member are fixed relative to the cutting deck.

11. The lawn mower of claim 10 , wherein the mounting member captures the mulching insert between the flange and an inner surface of the cutting deck.

12. The lawn mower of claim 10 , wherein the spindle housing includes an outer surface and threads formed in the outer surface, and wherein the mounting member threadably engages the threads of the spindle housing.

13. The lawn mower of claim 10 , further comprising a bearing positioned between the spindle and the spindle housing.

14. The lawn mower of claim 13 , wherein an inner race of the bearing contacts the spindle and an outer race of the bearing contacts the spindle housing.

15. The lawn mower of claim 10 , wherein the mulching insert consists of a molded, single-piece body.

16. The lawn mower of claim 10 , wherein the flange includes an upwardly facing surface, and wherein the flange supports the mulching insert on the upwardly facing surface.
