3. Speed Control (if equipped) - To change speed,
move speed control to the desired speed.
NOTE: When selecting a drive speed, use the first
speed until you are comfortable and familiar with the
operation of the mower.
IMPORTANT: If you are shifting speeds while the
mower is stationary it may be difficult to shift into
first speed under certain conditions. This is easily
remedied by briefly engaging the drive lever.
NOTE: Your mower is equipped with an advanced
internal drive system for ease of use and smooth
shifting. When turning or pulling the unit rearward,
you may notice higher than normal resistance in the
rear wheels under certain conditions. This is perfectly
normal and can be remedied by allowing the unit to
roll forward slightly without the drive lever(s) engaged
before pulling backwards.
Using Side Discharge Chute
(If Equipped)
To use the mower without mulching or collecting grass,
remove the grass catcher and ensure the rear mulch
plug (if equipped) is installed. Allow the rear discharge
door to close the rear opening of mower. Refer to
Attaching The Side Discharge Chute in on page 11.
Using Mower as a Mulcher (If Equipped)
For mulching grass, remove the grass catcher or side
discharge chute from the mower. When you remove
the grass catcher from the mower, ensure the rear
mulch plug (if equipped) is installed and allow the rear
discharge door to close the rear opening of mower.
When you remove the side discharge chute, the
mulching plug will close. For effective mulching, do not
cut wet grass. If the grass has been allowed to grow in
excess of four inches, mulching is not recommended.
Use the grass catcher to collect clippings instead.
Using Mower with Grass Catcher
(If Equipped)
You can use the grass catcher to collect clippings while
you are operating the mower.
1. Attach grass catcher, refer to Attaching the
Grass Catcher on page 10. Grass clippings will
automatically collect in bag. Operate mower until
grass bag is full.
2. Stop engine by releasing the blade control. Make
sure that the engine has come to a complete stop.
3. Lift rear discharge door and pull grass bag up
and away from the mower to remove the bag.
Dispose of the grass clippings and reinstall the bag
when complete.
WARNING: If you strike a foreign object, stop
the engine. Disconnect the spark plug wire,
thoroughly inspect mower for any damage,
and repair damage before restarting and
operating. Extensive vibration of mower
during operation is an indication of damage.
The mower should be promptly inspected
and repaired.
WARNING: Before performing any type of
maintenance/service, disengage all controls
and stop the engine. Wait until all moving
parts have come to a complete stop. Allow
the engine to cool. Disconnect spark plug
wire and ground it against the engine to
prevent unintended starting.
