3.3 3-in-1 Mowing Options

The 21-inch steel deck provides three versatile mowing options:

• Mulching: Finely cuts and redistributes clippings back onto the lawn as natural fertilizer. Ensure the mulch plug is installed.
• Side Discharge: Disperses clippings out of the side chute, ideal for taller grass or when bagging is not desired.
