Speed Control
The speed control is located on the variable speed control

IMPORTANT: Move the speed control only when the engine is
running. Changing the speed control setting with the engine off
can damage the mower.
NOTE: The speeds noted on the speed control are not exact.

conditions.

The mulch plug is used for mulching purpose. Instead of

has the option of recirculating the clippings back to the lawn.
Make sure that the rear discharge door is closed and the grass
catcher is removed from unit while mulching.
