Check the grass catcher components and the discharge
guard frequently and replace them with the manufacturer’s
recommended parts when necessary.

Use accessories and attachments approved by the
Lawn-Boy® Inc. only.

Slope Safety

Mow across the face of slopes; never up and down. Use
extreme caution when changing direction on slopes.

Do not mow on excessively steep slopes. Poor footing
could cause a slip-and-fall accident.

Do not mow near drop-offs, ditches, or embankments.
You could lose your footing or balance.

Starting the Engine

against the

Note:

If the machine does not start after several

attempts, contact an Authorized Service Dealer.

Using the Self-propel Drive

To operate the self-propel drive, squeeze the self-propel drive
bar (

Figure 14

toward the handle and hold it.

Self-propel drive bar

To disengage the self-propel drive, release the self-propel
drive bar.

Note:

The maximum self-propel ground speed is fixed. To

reduce the ground speed, increase the space between the
self-propel drive bar and the handle.

Shutting Off the Engine

Service Interval:

Before each use or daily

To shut off the engine, release the blade-control bar (

Figure

15

).

Note:

Remove the ignition key when you leave the machine

(electric-start model only).

Important:

When you release the blade-control bar,

both the engine and blade should stop within 3 seconds.
If they do not stop properly, stop using your machine
immediately and contact an Authorized Service Dealer.

Mulching the Clippings

Your machine comes from the factory ready to mulch the
grass and leaf clippings back into the lawn.

If the grass bag is on the machine, remove it before mulching
the clippings. Refer to

Removing the Grass Bag (page 9)
