Why does my Walker MT Lawn Mower horn sound at the wrong time?
- Vveronica87Jul 29, 2025
The horn may sound at the wrong time because the vertical position of the Grass-Pak[®] switch is critical to ensure the catcher box doesn't overfill, which could clog the delivery chute. To resolve this, adjust the Grass-Pak[®] switch by bending its mounting bracket until the measurement between the exhaust screen and the Grass-Pak[®] switch actuator vane is between 4 and 4-1/2 inches (10.16 and 11.43 cm). Make adjustments in small increments, checking the measurement each time until it's correct.
