ting performance decreases or the quality of cut
is poor, make the following changes.
1. When you mow, make sure the throttle con-
trol is in the FAST position.
2. (Figure 6) Move the blade rotation control (1)
to the DISENGAGE position (8).
3. Stop the engine. Disconnect the wire from
the spark plug.
4. Check the blade(s). Keep a sharp edge on
the blade(s). A blade that is not sharp will
cause the tips of the grass to become brown.
5. If the quality of cut has not improved, replace
the mower drive belt. See "How To Replace
The Mower Drive Belt". If the replacing the
belt does not correct the problem, take the
unit to an authorized service center.
6. Move the blade rotation control (1) to the
DISENGAGE position (8). Stop the engine.
Disconnect the wire from the spark plug.
7. (Figure 14) Check the operation of the blade
brake. Rotate the pulley with your hand.
Make sure that the brake pad (7) is pressed
tightly against the pulley.
WARNING: If the brake pad (7) does
not press tightly against the pulley,
take the unit to an authorized ser-
vice center.
8. (Figure 6) Move the blade rotation control
(1) to the ENGAGE position (9).
9. (Figure 14) Check the pads for the blade
brake (7). If the pads are excessively worn
or damaged, replace the brake pad assem-
blies. Correct replacement parts and assist-
ance are available from an authorized
service center.
10. Attach the wire to the spark plug. Mow for a
short distance and again check the operation
of the blade rotation control.
11. When you move the blade rotation control to
the DISENGAGE position, all movement will
stop within five seconds. If there is move-
ment of the belt or the blades continue to ro-
tate, engage and disengage the blade
rotation control five times to remove any ex-
cess rubber from a new mower drive belt. If
you need assistance, take the unit to an
authorized service center.
How To Adjust
The Speed Control Pedal (Figure 26)
Before you make an inspection,
adjustment, or repair to the unit,
disconnect the wire to the spark
plug. Remove the wire from the spark plug
to prevent the engine from starting by acci-
dent.
If a drive belt becomes worn or after installation
of a new drive belt, the speed control pedal may
need an adjustment. There are two indications
that an adjustment is needed. First, when the
speed control pedal is fully depressed the unit
does not achieve top speed. Second, when the
speed control pedal is released, the unit does
not come to a complete stop.
1. Check the routing of the engine drive belt
(1). Make sure the belt is installed correctly
and is inside all the belt guides (2).
2. Remove the cotter pin and washer from the
adjustable nut (3).
F–030601L
3. If the unit is not achieving top speed, then
turn the adjustable nut (3) towards the end
of the drive link (4). If the unit does not
come to a complete stop, then turn the ad-
justable nut (3) toward the center of the
drive link (4).
4. Assemble the adjustable nut (3) to the pivot
link. Fasten with the washer and cotter pin.
How To Adjust The Shift Lever
(Figure 15)
If the NEUTRAL position on the shift lever does
not match neutral on the gearbox, adjust the
shift lever as follows.
1. Stop the engine.
2. Disconnect the adjuster nut (2) from the
shifter yoke (3).
3. Make sure the shift lever is in the NEUTRAL
position.
4. Push the unit forward. Make sure the gear-
box is in neutral.
5. To align the adjuster nut (2) with the hole in
the shifter yoke (3), turn the adjuster nut
(2).
6. Connect the adjuster nut (2) to the shifter
yoke (3).
7. Make sure the NEUTRAL position on the
shift lever matches neutral on the gearbox.
How To Check And Adjust The Clutch
(Figure 16)
If the motion drive belt is loose, the clutch will
slip when; going up a hill, pulling a heavy load,
or the unit will not move forward. Adjust the
clutch as follows.
WARNING: Before you make an in-
spection, adjustment, or repair to
the unit, disconnect the wire to the
spark plug. Remove the wire from the
spark plug to prevent the engine from
starting by accident.
1. Check the routing of the motion drive belt.
Make sure the belt is installed correctly and
is inside all the belt guides.
2. Remove the hair pin (1) and washer (2)
from the adjustable nut (4).
3. Disconnect the adjustable nut (4) from the
clutch pivot link (5).
4. Pull the clutch pivot link (5) forward until
tight.
5. Pull the clutch rod (6) toward the rear and
turn the adjustable nut (4) until the adjust-
able nut (4) is aligned with the rear of the
slot.
6. Assemble the adjustable nut (4) to the
clutch pivot link (5). Fasten with the
washer (2) and hair pin (1).
7. If the belt still slips after the clutch has been
adjusted, then the motion drive belt is worn
or damaged and must be replaced. See
"How To Replace The Motion Drive Belt".
How To Check And Adjust The Drive
Brake (Figure 17)
Completely push the clutch/brake pedal forward.
Set the parking brake. Move the shift lever to the

1. The location of the drive brake (1) is on the
left side of the gearbox (3).
2. Make sure the parking brake is set and the
shift lever is in neutral (N). Turn the hex nut
(2) in a clockwise direction until the rear
wheels do not turn when the unit is pushed
forward.
3. Release the parking brake and push the unit.
If the unit does not roll, turn the hex nut (2)
in a counter–clockwise direction until the unit
rolls.
4. Set the parking brake. Push the unit. If the
