Installation Instructions
This section outlines the steps for replacing or installing the discharge door assembly. A small screwdriver and pliers may be required.
- Prepare the Mower: Park the lawn mower on a flat, stable surface. Ensure the engine is completely off and cool. Disconnect the spark plug wire to prevent accidental starting.
- Locate the Old Assembly: Identify the existing discharge door assembly on the mower deck. It is typically located on the side of the deck where grass clippings are expelled.
- Remove the Old Assembly: Carefully detach the old discharge door assembly. This usually involves removing pins, bolts, or springs that secure it to the mower deck. Use a small screwdriver and pliers as needed to disengage retaining clips or springs. Note the orientation of the old assembly for correct installation of the new part.
- Install the New Assembly: Position the new Toro 106-8376 Discharge Door Assembly in the same orientation as the old one. Secure it to the mower deck using the existing hardware or any new hardware provided (if applicable). Ensure all pins, bolts, and springs are correctly reattached and seated firmly.
- Verify Installation: Gently open and close the new discharge door to ensure it operates smoothly and closes securely. Check for any loose connections or parts.
- Reconnect Spark Plug: Once installation is complete and verified, reconnect the spark plug wire.

Operation
The discharge door assembly is a critical component for safe and effective lawn mower operation. Its primary function is to cover the discharge opening of the mower deck, preventing debris from being ejected towards the operator or bystanders during mowing.
- Closed Position: The discharge door should remain closed during normal mowing operations, especially when using a mulching plug or bagger, to direct clippings appropriately or contain them within the deck.
- Open Position (Side Discharge): If your mower is configured for side discharge, the door may be designed to remain open or be held open by an attachment to allow clippings to exit. Always ensure the area is clear of people and obstacles when operating with side discharge.
Maintenance
Regular inspection and maintenance will extend the life of your discharge door assembly and ensure safe operation.
- Clean Regularly: After each use, clean grass clippings and debris from around the discharge door and its hinges. Accumulated debris can hinder proper operation.
- Inspect for Damage: Periodically check the discharge door for cracks, bends, or other damage. Ensure the springs (if applicable) are intact and providing adequate tension.
- Check Hardware: Verify that all mounting hardware (pins, bolts, nuts) is secure and not corroded. Tighten or replace as necessary.
- Lubrication: Apply a light lubricant to the hinge points if the door becomes stiff or squeaky.
Troubleshooting
