Cutting Deck Design and Grass Handling Features

The John Deere 322 mower features a durable 48-inch Accel Deep™ cutting deck, designed to deliver clean, precise cuts. The deck’s deep design improves airflow, lifting grass blades for a more consistent cut and better discharge. This ensures an even finish, even in thicker grass.
The deck’s construction uses heavy-duty materials to withstand impacts and ensure long-lasting performance. The welded steel deck provides extra strength, preventing damage from rough terrain or obstacles during operation.
Grass handling is made efficient with a high-performance discharge system. The deck channels clippings into the side discharge chute, reducing clogging. The chute’s design minimizes the likelihood of grass build-up, ensuring smooth operation throughout the mowing process.
The 322 mower also features an optional mulch kit, which finely chops the grass and disperses it evenly across the lawn. This reduces the need for bagging and contributes to a healthier lawn by returning nutrients to the soil.
For ease of maintenance, the cutting deck is equipped with a wash port, allowing users to clean the underside of the deck after mowing. Regular cleaning improves the mower’s performance and longevity, keeping the deck free of grass clippings and debris that could affect its operation.
