Setup and Installation
This section outlines the general steps for installing the lower bagger chute. Refer to your specific mower's operator manual for detailed diagrams and safety precautions.
- Prepare the Mower: Ensure the mower engine is turned off, the key is removed, and the spark plug wire is disconnected to prevent accidental starting. Allow the cutting deck to cool.
- Remove Old Chute (if applicable): If replacing an existing chute, carefully detach it from the mower deck and the upper bagger tube. Note how it was connected.
- Position the New Chute: Align the lower end of the AM143911 chute with the discharge opening on the mower deck.
- Secure to Deck: The chute typically attaches to the mower deck using pins or clips. Ensure these connections are secure and the chute is firmly seated. Some models may require a slight adjustment or enlargement of the attachment hole on the deck for a perfect fit. If the hole is slightly too small, a drill bit can be used to carefully enlarge it.
- Connect to Bagger Tube: Connect the upper end of the lower chute to the main bagger tube that leads to the collection bags. Ensure a tight seal to prevent grass clippings from escaping.
- Verify Fit: Double-check all connections to ensure the chute is securely attached and there are no gaps that could lead to clogging or inefficient bagging.

Operating the Bagger Chute
Once installed, the lower bagger chute works in conjunction with your mower's cutting deck and bagging system to direct grass clippings into the collection bags. Proper operation involves ensuring the chute remains clear and securely attached during mowing.
- Ensure the bagger chute is securely attached to both the mower deck and the upper bagger assembly before starting the mower.
- Mow at an appropriate speed for the grass conditions to prevent clogging.
- Regularly check the collection bags and empty them before they become too full, as overfilled bags can lead to reduced airflow and clogging in the chute.
Maintenance
Regular maintenance of your lower bagger chute will ensure its longevity and optimal performance.
- Cleaning: After each use, or as needed, remove the chute and clear any accumulated grass clippings, dirt, or debris from both the inside and outside surfaces. A stiff brush or hose can be used. Ensure the chute is dry before reattaching or storing.
- Inspection: Periodically inspect the chute for signs of wear, cracks, or damage. Pay close attention to the connection points. A damaged chute can lead to poor bagging performance or become a safety hazard. Replace the chute if any significant damage is observed.
- Storage: Store the chute in a clean, dry place when not in use, especially during off-season, to protect it from elements and prolong its life.
