Operation
Install the Mulcher Plate
1. Raise the deflector (1) (see Figure 8). Mount the
bottom flange of the mulcher plate (4) to the mower
housing.
2. Slide the top of the mulcher plate (4) under the
deflector bracket (5) (see Figure 9).
3. Fasten the mulcher plate with two wingnuts (2) and
two carriage bolts (3) (see Figure 8).

Mulching Tips
When you use a mulcher attachment, the grass is cut into
very small pieces. These small pieces will quickly break
down. Because the nutrients are returned to the soil, the
lawn will need less fertilizer. To correctly mulch the grass,
follow the steps below.
1. Set the throttle control lever (7) in the FAST position
(see Figure 7). Operate the mower at a slower
ground speed. If ground speed is too fast, the grass
will not have an even cut.
2. Keep a sharp edge on the blade. A blade that is not
sharp will cause the ends of the grass to become
brown.
3. Make sure the grass is dry. Wet grass is difficult to
cut.
4. Set the height of the mower housing so that only the
top third of the grass is cut. If the grass is too high,
set the height of the mower housing to the maximum
height. Then, lower the mower housing for the second
cut. Also, instead of using the full width of the mower
housing, mulch at half the width.
5. Clean the bottom of the mower housing. Grass and
other debris can keep the mower from working
correctly.
6. If the grass grows fast, mulch more often.
7. If an area needs improvement, mulch a second time.

Operate with the Mower Housing
WARNING
The deflector is a safety device. Do not remove
the deflector. The deflector forces the discharged
material toward the ground. Always keep the
deflector in the DOWN position. If the deflector is
damaged, replace the deflector with an original
equipment part from an authorized service center.
IMPORTANT: When you operate with the mower
housing, always operate with the throttle control in
the FAST position.
1. Start the engine.
2. Release the parking brake lever (6) (see Figure 7).
3. Move the lift lever (5) to a height of cut position. In
high or thick grass, cut the grass in the highest
position first and then lower the mower housing to a
lower position.
4. Move the throttle control lever (7) to the SLOW
position.
5. Slowly move the blade rotation control (1) to the
ENGAGE position.
6. Move the throttle control lever to the FAST position.
7. Slowly push the speed control pedal (8) to the
desired speed.
NOTE: When you mow in heavy grass or mow with a
bagger, use a slow forward speed.
8. Make sure the level of cut is still correct. After you
mow a short distance, look at the area that was cut.
If the mower housing does not cut level, see "Level
the Mower Housing" in the Maintenance section.
WARNING
For better control of the unit, select a safe speed.
