Your Craftsman mower's mulch plug and deflector chute control where cut grass goes—missing, cracked, or broken versions force clippings into your face or create uneven discharge patterns. A damaged plug also reduces mulching efficiency and can allow debris into the deck housing. Genuine OEM replacements snap into place and restore safe, efficient operation quickly.
Whether you need a mulch plug to block the side chute or a deflector to redirect grass down, Repair Clinic carries genuine Craftsman parts for your model. Find your Craftsman deflector and mulch plug parts to cut safely and effectively.
A mulch plug blocks one discharge path entirely, forcing all clippings back into the deck for re-cutting. A deflector chute redirects grass flow—typically from side discharge to rear or vice versa. Craftsman mowers often use both together: the plug seals one chute while the deflector channels grass the way you want it.
A missing or loose mulch plug leaves the side chute open, sending clippings toward you instead of down. Check that your plug is seated all the way into the chute bracket and snapped tight. If it's cracked or the plastic tab is broken, replacement is your safest bet.
Technically yes, but not safely. Without it, discharge is unpredictable—grass may shoot sideways or upward. You also expose the open chute port to debris and moisture, risking internal deck corrosion. OEM plugs are inexpensive insurance against injury and equipment damage.
Deflector style varies by deck design and cutting system. Always reference your model number on the frame. Repair Clinic's parts finder matches the exact chute orientation and mounting bracket to your mower, guaranteeing a compatible fit and proper grass flow.

Craftsman places the model number on a label near the mower deck or frame on many walk-behind models. If you have a riding mower, check under the seat, along the frame below the steering column, or on the rear fender. Clean off grass and dirt so you can read every letter and number, including any prefix or suffix. Enter the complete model number in the search bar to narrow the catalog to parts that fit your Craftsman mower, including parts across every part category. Matching the full model number helps account for differences in deck size, engine design, and production year. That means fewer wrong orders and a faster repair.
