5. Installation Instructions
Follow these steps to properly install the side discharge chute assembly on your lawn mower. Ensure all safety precautions are observed before beginning.
- Prepare the Mower: Park the lawn mower on a flat, stable surface. Turn off the engine, remove the ignition key (if applicable), and disconnect the spark plug wire to prevent accidental starting.
- Locate Discharge Opening: Identify the side discharge opening on your mower deck. This is typically covered by a mulching guard or an existing chute.
- Remove Old Chute (if applicable): If replacing an existing chute, carefully remove it. This usually involves lifting the mulching guard and unhooking the old chute from its pivot points or spring mechanism.
- Position the New Chute: Align the MTD 631-05229 Side Discharge Chute Assembly with the mower's discharge opening. The metal hinge bracket on the chute should correspond with the attachment points on the mower deck.
- Attach the Chute: Lift the mower's mulching guard. Slide the pins or clips of the chute assembly into the corresponding slots or holes on the mower deck's hinge mechanism. Ensure the spring is correctly seated to provide tension, holding the chute in place.

- Verify Secure Attachment: Gently pull on the chute to ensure it is firmly attached and does not wobble. The spring mechanism should hold it securely against the mower deck.
- Reconnect Spark Plug: Once installation is complete and verified, reconnect the spark plug wire.
6. Operation
The side discharge chute is designed to direct grass clippings out from under the mower deck and away from the operator. When mowing, ensure the chute is properly installed and unobstructed. The chute will naturally pivot to allow clippings to exit. Avoid mowing in areas where discharged clippings could cause damage or injury to property or individuals.
7. Maintenance
Regular maintenance of your side discharge chute assembly will ensure its longevity and optimal performance.
- Cleaning: After each use, clean any accumulated grass clippings and debris from the chute, especially around the hinge mechanism. A stiff brush or scraper can be used.
- Inspection: Periodically inspect the plastic chute for cracks, breaks, or signs of wear. Check the metal hinge bracket and spring for corrosion or damage.
- Lubrication: If the hinge mechanism becomes stiff, apply a small amount of general-purpose lubricant to the pivot points.
- Storage: Store the mower and chute in a dry, protected area to prevent rust and material degradation.
