WARNING
This machine meets voluntary safety standard B71.1 –
1998, which is sponsored by the Outdoor Power
Equipment Institute, Inc., and is published by the American
National Standards Institute.
Safety Alert Symbol
This is a safety alert symbol. It is used in this
manual and on the unit to alert you to potential
hazards. When you see this symbol, read and
obey the message that follows it. Failure to obey
safety messages could result in personal injury or property
damage.
I. GENERAL OPERATION
1. Read, understand and follow all
instructions on the machine and in
the manuals provided with the unit.
Be thoroughly familiar with the
controls and the proper use of the
mower before starting.
2. Do not put hands or feet near or
under rotating parts. Keep clear of
the mower blade and discharge
opening at all times.
3. Only allow responsible individuals,
who are familiar with the instructions, to operate the mower.
4. Clear the area of objects such as
rocks, toys, wire, bones, sticks, etc.,
which could be picked up and thrown
by the blade.
5. Be sure the area is clear of other
people before mowing. Stop mower if
anyone enters the area. Keep
bystanders at least 25 feet away from
the area of operation.
6. Do not operate the mower when
barefoot or wearing open sandals.
Always wear substantial foot wear.
7. Do not pull mower backwards unless
absolutely necessary. Look down and
behind before and while moving
backwards.
8. Do not operate mower without all
guards in place and either the entire
Grass Catcher, the Mulching Plug or
the Side-Discharge Chute installed.
ROTATING BLADES— Do not open
discharge guard while engine is
running.
9. Refer to provided instructions for
proper operation and accessory
installation. Use only accessories
approved by Garden Way Inc.
10. Shut off engine when crossing gravel
drives, walks, or roads.
11. Stop engine and disconnect spark
plug wire from spark plug whenever
you leave unit, before cleaning mower
or unclogging chute.
12. Shut the engine off and wait until the
blade comes to a complete stop
before installing or removing the
Mulching Plug, Side-Discharge Chute
or the Grass Catcher. Make certain
that an attachment is installed before
operating the mower. Empty the
Grass Catcher after each use–
decomposing debris could generate
enough heat to catch fire.
13. Mow only in daylight or in good artificial light.
14. Do not operate mower while under
the influence of alcohol or drugs.
15. Never operate mower in wet grass.
Always be sure of your footing; keep
a firm hold on the handle and walk;
never run.
16. Be sure Wheel Drive Bail is disengaged before starting engine.
17. If the unit should start to vibrate
abnormally, stop the engine and disconnect the spark plug wire. Then
check immediately for the cause.
Vibration is generally a warning of
trouble.
18. We recommend that you wear safety
goggles or safety glasses when
operating the mower.
19. Watch for traffic when operating
near, or when crossing roadways.
20. Never attempt to carry children or
other passengers on the mower.
They could fall off and be seriously
injured, or they could interfere with
the safe operation of the mower.
21. Check the operation of the Operator
Presence Control Bail (top bail,
mounted on handlebar) before each
use. The Operator Presence Control
Bail is a safety device that is designed
to stop the mower blade within three
seconds after releasing the bail. The
bail must operate freely when pulled
back against the handlebar and
return automatically to the disengaged position when released. If the
engine runs longer than three
seconds after releasing the bail, the
system is not working properly.
Immediately contact an authorized
service dealer or the Factory
Technical Service Department for
instructions. Do not use the mower
until the mechanism is repaired.
22. Never run the engine in an enclosed
area. Engine exhaust contains carbon
monoxide, a deadly gas that is
odorless, colorless and tasteless.
Always run the engine outdoors and
make sure there is adequate
ventilation.

II. OPERATING ON A SLOPE
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury. All slopes require extra
caution. If you feel uneasy on a slope,
do not mow it.
DO:
Mow across the face of slopes; never
up and down. Exercise extreme
caution when changing direction on
slopes. Avoid slopes greater than 15
o
.
Remove objects such as rocks, tree
limbs, etc.
Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
Do not mow near drop-offs, ditches,
or embankments. The operator could
loose footing or balance.
Do not mow excessively steep slopes.
Do not mow on wet grass. Reduced
footing could cause slipping.
III. CHILDREN
Tragic accidents can occur if the
operator is not alert to the presence of
children. Children are often attracted to
the mower and to the mowing activity.
Never assume that children will remain
where you last saw them.
1. Keep children out of the mowing area
and under the watchful care of a
responsible adult.
2. Be alert and turn mower off if
children enter the area.
3. Before and while moving backwards,
look behind and down for small
children.
4. Never allow children to operate the
mower.
5. Use extra care when approaching
blind corners, shrubs, trees, or other
objects that may obscure vision.
IV. SERVICE
1. Use extra care in handling gasoline
and other fuels. They are flammable
and their vapors are explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel
when the engine is running.
Allow engine to cool before
refueling. Do not smoke.
c) Never refuel the machine
indoors.
d) Never store the machine or fuel
container inside where there is an
open flame, such as a water
heater, etc.
e) Move mower away from any
gasoline fumes before starting
the engine.
2. Never run an engine inside a closed
area.
3. Never make adjustments or repairs
with the engine running. Disconnect
the spark plug wire and move the
wire away from the plug to prevent
accidental starting.
4. Keep all nuts and screws, especially
the blade attachment bolts, tight and
keep equipment in good condition.
5. Never tamper with safety devices.

The Operator Presence Control Bail
(A, Figure 3-1) must be pulled back
against the handlebar and held there
while starting the engine and operating
the unit. Releasing the bail will shut off
the engine and stop the mower blade.
The engine will not restart unless the bail
is pulled back against the handlebar.
NOTE: This control disengages an engine
brake when pulled back against the
handlebar and engages the engine brake
when released. The mower blade is
bolted directly to the engine shaft,
therefore it stops when the engine stops.
The engine will not restart unless the bail
is pulled back against the handlebar. See
Stopping the Engine and Mower Blade in
Section 4 for more information.
Wheel Drive Bail
The Wheel Drive Bail (C, Figure 3-1)
engages the powered rear wheels when it
is pulled up against the handlebar, and
disengages the wheels when released.
See Mowing and Turning the Mower in
Section 4 for more information.
To move the mower without engine
power, release the controls and push or
pull the mower.
NOTE: The pinion gears inside the rear
wheels may produce an occasional
knocking sound when pushing or pulling
the mower manually. This sound is
harmless. Do not lubricate the drive
wheels. Service the drive assembly only
as instructed in Section 5.
Wheel Speed Control
The Wheel Speed Control (B, Figure 3-1)
provides three different wheel speeds.
Selections are:
• 1 for low speed
• 2 for medium speed
• 3 for high speed
See Mowing in Section 4 for more information.
Cutting Height Adjustment Lever
This control (K, Figure 3-1) provides eight
cutting heights, enabling you to choose
the most appropriate height for the lawn
condition. Cutting heights range from
3/4-inches to 4-1/4-inches. See Prepara-
tion for Mowing in Section 4 for more
information.
NOTE: Actual cutting height will vary
according to turf conditions..

Operation
INTRODUCTION
Read this Section thoroughly before you
start the engine. Then take the time to
familiarize yourself with the mower’s
basic operation.
Find an open, level area and practice
using the mower controls. Only after you
become familiar with the mower should
you use it in smaller areas or on uneven
terrain.
CUB CADET
®
RAPID ATTACHTMSYSTEM
The Rapid Attach System (Figure 4-1) is a
feature designed into the mower deck
which enables you to install and remove
the Grass Catcher, the Side-Discharge
Chute and the Mulching Plug quickly and
easily.
The Grass Catcher and the Side-Discharge
Chute both use the same system. This
system consists of an elongated tab (A,
Figure 4-1) on the top of the discharge
outlet and a receptacle (B) built into the
top of the Grass Catcher door and the
Side-Discharge Chute.
Attaching the Mulching Plug is just as
easy. Hold open the discharge outlet
guard (K, Figure 4-1) and insert the plug
(L), with the word “TOP” facing up, into
the discharge outlet.
SETTING UP MOWING MODES
The lawn mower has three mowing
modes: bagging mode, mulching mode
and side-discharge mode. The following
provides descriptions of the three modes
and how to implement them.
Bagging Mode
The mower is set up for bagging mode
when the Grass Catcher is attached to the
discharge outlet.
The Grass Catcher is equipped with two
handles and a swing-open door that
makes emptying easy. Use the wireformed handle to help attach, remove,
transport and empty the bag. Use the
rear cloth handle to lift the bottom of the
bag when emptying.
The Grass Catcher also has a Smart Bag
TM
grass-fill indicator (Figure 4-3) which
makes it easy to tell when the bag is full.
The indicator is a rectangular piece of
cloth sewn to the top of the bag. The
indicator lays flat against the bag when
the bag is full (F, Figure 4-3) and billows
(G) when the bag is not full.
NOTE: Windy conditions may affect the
indicator’s ability to provide an accurate
bag fill reading.
Setting Up Bagging Mode
1. With the engine and blade stopped,
remove the Mulching Plug or SideDischarge Chute.
2. Grasp the Grass Catcher by the wireformed handle. With the other hand, hold
open the discharge outlet guard (C, Figure
4-2).
3. Lower (at an angle) the bag door (D,
Figure 4-2) onto the tab (E) on the
discharge outlet. Make sure the bag door
seats squarely onto the tab and covers
the tab completely.
Removing the Grass Catcher
1. When mowing, the Grass Catcher is
full when the grass fill indicator lays flat
against the bag (F, Figure 4-3).
An alternative method for judging bag
fullness is to nudge the bag with your
foot. The bag will give easily when not
full, and will resist when full.
• Never operate the mower with the
discharge outlet guard removed or
propped open.
• Do not operate mower without the
Grass Catcher, Mulching Plug or SideDischarge Chute in place.
• Never change mowing modes or
empty the Grass Catcher while the
engine is running.
• Check the condition of the Grass
Catcher for excessive wear or deterioration. If damaged, contact an authorized dealer or the factory for a
replacement.

against the edge of the discharge outlet to
ensure efficient mulching (Figure 4-4).
Removing the Mulching Plug
1. With the engine and blade stopped, lift
open the discharge outlet guard.
2. Grasp the Mulching Plug’s hand-grip
with one hand and pull back until the plug
clears the discharge outlet.
Side-Discharge Mode
Use the Side-Discharge Chute to disperse
grass clippings onto the lawn.
Setting Up the Side-Discharge Chute
1. With the engine and blade stopped,
remove the Grass Catcher or Mulching
Plug.
2. Lift open the discharge outlet guard
(K, Figure 4-1) and lower the SideDischarge Chute opening (B, Figure 4-1)
onto the discharge outlet tab (A). Make
sure it covers the tab completely.

open on the discharge outlet guard (K,
Figure 4-1).
2. With the other hand, grasp the SideDischarge Chute and guide it up and off
the discharge outlet tab.
PREPARATION FOR MOWING
Review Section 1: Safety and Section 3:
Features and Controls. Then read this
Section completely before starting the
mower.
1. Move lawn mower to a clear, level
area - If on a grassy area, make sure the
grass is low enough as to not interfere
with blade rotation when starting.
2. Inspect area to be cut - Check for and
remove debris such as rocks, toys, wire,
bones, sticks, etc., which could be picked
up and thrown by the blade. Also inspect
the terrain for holes or other obstacles.
3. Check mower -
• Check the mower for loose or missing
hardware. Tighten or replace before
starting the mower.
• Check the Operator Presence Control
Bail for freedom of movement.
• Check the Wheel Drive Control Bail for
freedom of movement.
• Check blade for excessive wear or
damage. Do not operate the mower
with a damaged blade.
• Securely connect the spark plug wire to
the spark plug.
4. Adjust handlebar height - The mower
has three handlebar heights which can be
adjusted as follows:
a. Loosen one of the lower handlebar
adjustment knobs (H, Figure 4-5) and
give the knob a tap to free the
handlebar strut (K) for adjustment.
Repeat for the other side.
b. Adjust the handlebars to the
desired height and then tighten the
handlebar adjustment knobs. Make
sure that the square shank on the
screw (J, Figure 4-5) seats squarely
into one of the square slots (I).
5. Set cutting height - You can set the
mower to any of eight cutting heights.
Cutting heights range from 3/4" to 4-1/4".
NOTE: Actual cutting height will vary
according to grass, terrain, and soil conditions.

WARNING
Page 12
Section 4: Operation
a. To adjust cutting height, pull the
Cutting Height Lever (A, Figure 4-6)
away from the mower to release the
tab from the slot. Be sure to grip the
lever firmly to prevent the mower deck
from dropping down rapidly.
b. While pulling the lever away from
the mower, move the lever towards the
back of the mower (B, Figure 4-6) for a
higher cut or towards the front of the
mower (C) for a lower cut.
c. Seat the lever’s tab squarely into
the slot.
IMPORTANT: The mower is equipped
with a safety flap located on the rear of
the mower deck. After setting the cutting
height, be certain that the flap hangs
freely and is not caught under the deck.
6. Prepare Engine -
• Check oil level - If this is a new mower,
add motor oil as described in the Engine
Owner’s Manual; otherwise, check oil
level and add as recommended in the
Engine Owner’s Manual.
• Add fuel - Fill the fuel tank with gasoline
according to the directions in the
separate Engine Owner’s Manual.
Follow all instructions and Safety rules
carefully.
• Check air filter - The engine is
equipped with an air filtration system.
When clogged, it causes starting difficulties and operates inefficiently. See
the Engine Owner’s Manual for information on how to maintain the air
filter system.
OPERATING THE MOWER
The following procedures explain how to
start, stop and operate the mower.
Starting the Engine
1. Open the fuel shut-off valve, if so
equipped.
2. Prime the engine by pushing the
primer bulb firmly 3 times.
NOTE: Priming may not be necessary
when restarting a warm engine.
However, cool weather may require
priming again. See the Engine Owner’s
Manual for priming information.
3. Stand behind the mower handlebar
and pull the Operator Presence Control
Bail (A, Figure 3-1) back against the
handlebar and hold.
4. Check behind you for obstacles, then
slowly pull the recoil rope (E, Figure 3-1)
until resistance is felt. Pull the rope out
rapidly to start engine. Let the rope
return slowly. If the engine fails to start
after three pulls, repeat steps 2-4.
Stopping the
Engine and Mower Blade
1. Release the Operator Presence Control
Bail (A, Figure 3-1) to stop the engine and
blade.
Emergency Stopping
Release all controls. This stops the
engine, wheel movement and the blade.
IMPORTANT: The mower is equipped
with a Blade Control System which is
designed to stop the mower blade within
three (3) seconds after releasing the
Operator Presence Control Bail. This
system also stops the engine.
Mowing
1. Start the engine. See Starting the
Engine in this Section.
2. Use the Wheel Speed Control to select
a wheel speed. The mower has three
wheel speeds. Select a slower speed
when first starting out (or when learning
how to use the mower), then move into
faster speeds if needed.
• Low Speed (1) - is engaged when the
lever is pulled all the way back. Low
speed provides the most efficient cut.
• Medium Speed (2) - is engaged when
the lever is moved to the middle detent
position (the control lever will click into
place). This speed is a good compromise for speed and cutting performance.
• High Speed (3) - is engaged when the
lever is pushed all the way forward.
High speed enables you to cover the
cutting area more quickly, but may
result in a less efficient cut.
To avoid personal injury, keep hands
and feet clear of mower blade or other
rotating parts.
If the Blade Control System does not
operate properly, the blade could
continue to rotate for longer than three
(3) seconds after releasing the Operator
Presence Control Bail. If this occurs,
discontinue using the mower and immediately contact your local authorized
dealer or the factory for instructions.
Do not operate the mower until the
Blade Control System is repaired.
Failure to do this could result in
personal injury or property damage.
GASOLINE IS HIGHLY FLAMMABLE AND
ITS VAPORS ARE EXPLOSIVE.
Follow the gasoline safety rules in this
Manual (Section 1) and in the separate
Engine Owner’s Manual.
Failure to follow gasoline safety instructions can result in serious personal
injury and property damage.
12
Do not operate the engine in an
enclosed area. Engine exhaust contains
carbon monoxide, a deadly gas that is
odorless, colorless and tasteless.
Always run the engine outdoors and
make sure there is adequate ventilation.
Figure 4-6: Cutting height adjustment.

MOWING TIPS AND HINTS
Mow When Lawn Is Dry
Do not mow grass when it is wet. Wet
grass is difficult to mow and clumps
together inside the mower housing. This
causes inefficient operation and an
uneven cut. Additionally, wet clippings
stick together in unsightly clumps on top
of the lawn which causes inefficient
absorption of nutrients back into the soil.
Avoid Midday Mowing
If possible, mow in the late afternoon or
early evening to avoid exposing newly cut
grass to the drying effects of direct
sunlight.
Never Cut Lower Than One-Third Grass
Height In One Pass
If possible, mow
often enough or
high enough to
avoid cutting off
more than 1/3 of
the grass height.
For example, if you
are maintaining your lawn at 2", mow
before it reaches 3".
Removing more than 1/3 of total grass
blade length may expose tender, shaded
stems to the drying effects of the sun and
wind and produce a dull, brown-looking
lawn. Cutting off too much leaf area is
also a shock to the root system and it
may take weeks to repair the damage.
Clean Mower Frequently
Clean the mowing housing frequently to
remove any grass build-up. Refer to the
cleaning instructions in Section 5.
Vary Cutting Pattern
Vary the cutting
pattern from week
to week. One week
mow horizontally.
Mow vertically the following week. This
helps prevent wear patterns and soil compaction.
Side-Discharge Mowing
When in Side-Discharge mode, try cutting
in a circular pattern with the chute
inward, facing the uncut area. This
results in less clumping by recutting the
clippings for a finer, cleaner appearance.
Avoid Sharp Turns
Sharp turns may produce an uneven cut.
If possible, follow natural ground
contours or use gentle, sweeping turns
for a better looking lawn.
Mow Long Grass Twice
If the grass
is 5" long or
more, cut it
once at the
highest
setting and then mow it again at the
desired height. This method may
produce too many clippings to use the
mulcher effectively. Use the Grass
Catcher to remove the grass clippings.
Use Extreme Caution on Slopes
When operating on
sloping ground,
exercise extreme
caution and use good
common sense to
avoid possible
personal injury or property damage.
Do not mow steep slopes! Avoid slopes
greater than 15 degrees, or wherever
footing is unsure. If a slope is difficult to
stand on, it is probably too steep to mow
(in such a case, it may be best to
establish a ground cover that doesn’t
require mowing).
Do not mow on slopes when the ground
is wet. Mow across the face of slopes,
never up and down. Slow down and
exercise extreme caution when changing
direction on slopes. Keep the Wheel
Drive Bail engaged to ensure easier
operation and better control of the mower
Empty Grass Catcher When Full
Emptying the Grass Catcher when it is full
results in better collection and mower
performance. Empty the bag as soon as
the bag is filled. See Bagging Mode for
more information on the Smart Bag
feature.
13
To avoid injury or property damage:
• Maximum safe operating angle is 15o.
• Exceeding maximum safe operating
angle may cause tipping or loss of
footing.
• Do not mow wet slopes.
• Mow across slopes, not up and down.
• Exercise extreme caution when
changing direction on slopes.

Section 4: Operation
Match Speed
To Terrain and Conditions
Adjust the speed to grass conditions and
terrain. Use Low and Medium speeds for
normal mowing conditions. You’ll get
better results at slower speeds, especially
if the grass is tall or lush. Use High speed
to transport the mower or when grass
conditions are light and appearance is not
as important.
Keep Mower Blade Sharp
A sharp blade cuts the grass cleanly,
resulting in a smooth, evenly cut lawn. A
dull blade tears at the grass and will fray
the tips so that they dry out quickly
resulting in a dull, brown-looking lawn.
See Blade Sharpening and Balancing in
Section 5 of this manual for more information.
Mulching Leaves
A light covering of leaves can be effectively mulched into the turf. As the leaves
decompose, they provide valuable organic
matter and minerals to the soil.
To ensure effective mulching, be sure the
leaves are dry. Use a slow travel speed
and don’t try to mulch a deep layer of
leaves.
NOTE: Oak leaves are acidic and may
affect the soil pH level when mulched. A
pH soil test should be used if oak leaves
are abundant on your property.
Page 15
ENGINE OIL SERVICE
Check the engine oil level before starting
the engine each day and after each 5
hours of continuous operation. Running
the engine when the oil level is low will
quickly ruin the engine.
Change engine oil after the first 2 hours
of break-in operation, thereafter, in accordance with your Engine Owners Manual.
Change more often in extremely dirty or
dusty conditions. Refer to the Engine
Owner’s Manual for detailed information
on changing oil.
SERVICING THE AIR CLEANER
The engine air cleaner filters dirt and dust
out of the air before it enters the carburetor. Operating the engine with a dirty,
clogged air cleaner can cause poor performance and damage to the engine.
Never operate the engine without the air
cleaner installed. Inspect and service the
air cleaner more often if operating in very
dusty or dirty conditions.
Service the air cleaner as instructed in the
separate Engine Owner’s Manual.
REMOVING AND
REPLACING THE BELT COVER
Removing the Belt Cover
1. Use a 3/8" wrench to remove both
screws (D, E, Figure 5-1).
2. Lift the back end of the cover then
carefully pull out.
Replacing the Belt Cover
1. Seat the rear end of the cover. Make
sure that both control cables are routed
through the cutout in the rear of the
cover. This will help prevent damage
caused by pinching the cables under the
cover or contact with the transmission
pulley or belt.
2. Tighten screws snugly. Do not overtighten (D, E, Figure 5-1).
TIPPING THE MOWER FOR
SERVICE
1. Before tipping the mower, make sure
that the fuel tank is empty to prevent the
possibility of gasoline spillage. See
“DANGER” statement that follows.

2. When servicing the underside of the
mower, the mower should be tipped only
in the direction of the muffler. Tipping
the mower away from the muffler could
result in engine damage or difficult
starting.
SPARK PLUG SERVICE
Inspect and clean or replace the spark
plug after every 100 operating hours or
annually. Set the gap as described in the
separate Engine Owner’s Manual.
In some areas, local law requires using
resistor spark plugs to suppress ignition
signals. If the engine was originally
equipped with a resistor spark plug,
replace with the same type.
CLEANING THE ENGINE
The engine must be kept clean to insure
smooth operation and to prevent damage
from overheating. Refer to the Engine
Owner’s Manual for more information.
CLEANING UNDER
THE MOWER HOUSING
Check the mower regularly for grass
build-up. Cleaning under the mower deck
should be done after (rather than before)
operating the mower, as grass is moist
and removed more easily.
1. Tip mower towards the muffler onto
its side. See Tipping the Mower for
Service in this Section.
2. Brush or scrape off grass build-up.
CLEANING THE GRASS CATCHER
Bag cleanliness affects collection performance as a dirty bag will restrict air flow.
Clean the Grass Catcher bag annually,
more often in dusty environments.
IMPORTANT: Do not wash or dry the
Grass Catcher in a washing machine or
dryer.
1. To clean the bag, remove it from the
mower and hand wash the fabric with
mild detergent.
2. Rinse the bag thoroughly with clean
water and allow to dry completely before
using. Do not use a damp bag.
CLEANING UNDER BELT COVER
Check underside of belt cover for grass
clippings every 10 hours of use.
1. Remove the belt cover. See
Removing the Belt Cover in this Section.
2. Remove any grass clippings or debris.
3. Replace belt cover. See Replacing the
Belt Cover in this Section.
SPARK ARRESTER
SCREEN SERVICE
If the engine muffler is equipped with a
spark arrester screen, remove and clean it
according to the time intervals and
instructions in the separate Engine
Owner’s Manual.
CARBURETOR/GOVERNOR
CONTROL ADJUSTMENTS
The carburetor was adjusted at the
factory for best operating speed. Refer to
the separate Engine Owner’s Manual for
any adjustment information or see your
authorized engine service dealer.
The governor controls the maximum safe
operating speed and protects the engine
and all moving parts from damage caused
by overspeeding. Do not tamper with the
engine governor settings. Seek authorized service if a problem exists.
MOWER BLADE MAINTENANCE
Blade Inspection
1. Tip mower towards the muffler onto
its side. See Tipping the Mower for
Service in this Section.
2. Inspect periodically for a dull or
slightly nicked blade. Sharpen if needed.
Also check for a deformed, cracked, or
excessively worn blade (Figure 5-2). Do
not use the mower if any of these conditions exist. Replace the blade immediately.
3. Check the blade screw for tightness.
If loose, tighten to 35 ft-lbs with a 3/4"
torque wrench.
Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, disconnect spark plug wire and move wire away from spark plug.
Failure to follow these instructions can result in serious personal injury or property damage.

Sharpening and
Balancing Mower Blade
IMPORTANT: We recommend that the
blade be sharpened by a professional
sharpening service. Replace a cracked or
severely worn blade with a new one.
1. Remove blade from the mower. See
Removing Mower Blade.
2. Clamp the blade in a vise. Use a metal
file or grinder to sharpen the blade while
maintaining the original cutting angle. It
is very important to maintain the original
cutting bevel to insure the most effective
cut.
3. To retain blade balance, remove the
same amount of material from both ends
of the blade.
4. To check blade balance, place the
blade on a rounded pivot such as a pencil
or pen under the center hole. Hold blade
parallel to ground then release. See
Figure 5-6. If blade is unbalanced, the
heavier side will lean downward.
5. Use a file to lightly remove material
from the heavier side of the blade.
6. See Installing Mower Blade for infor-
mation on how to re-install the blade.
REMOVING AND
REPLACING DRIVE BELT
This procedure can be made easier by
removing the blade (see Removing

Section 5: Maintenance
2. Fold the top section of the assembly
backward (2, Figure 5-16). Guide the
cables carefully while folding. Be sure
not to bend, pinch, or stretch the cables.
IMPORTANT: To avoid damage to cables,
always fold the top section of the
handlebar assembly backward and the
bottom section forward.
3. Still supporting the handlebar
assembly with one hand, loosen the two
lower handlebar adjustment knobs
(3, Figure 5-16) just enough to dislodge
both handlebar struts (L, Figure 5-17)
from the slots (K) in the wheel bracket
assembly.
NOTE: The handlebar height could inadvertently change if the lower adjustment
knobs are loosened excessively during
this step.
4. Carefully fold the bottom section of
the handlebar assembly forward over the
engine (4, Figure 5-16). Guide the cables
carefully while folding. Be sure not to
bend, pinch, or stretch the cables; also,
keep cables away from muffler — the
outer cable covering can be burned if the
engine is still hot.
5. To unfold handlebar assembly,
perform folding steps in reverse order.
PINION GEAR SERVICE
The mower drive wheels (rear wheels)
each contain a pinion gear. This gear
transfers drive power to the wheels which
propels the mower forward. It is very
important to keep these internal parts
clean. The following procedure explains
how to disassemble, clean and reassemble the mower drive wheels. Conduct this
maintenance on the pinion gears after
every 50 operating hours.
Tools and Materials
• 9/16" Socket and Ratchet
• Small Snap-Ring Pliers
• Cleaning Rags
Procedure
NOTE: This procedure is done only on
the drive wheels (rear wheels).
1. Place a sturdy, stable block under the
mower to elevate a rear wheel off the
ground.
2. Use a 9/16" wrench to remove wheel
assembly (A, B, C, D, E, Figure 5-18).
3. Remove snap-ring (J, Figure 5-18)
from axle.
4. Remove shim(s) (I, Figure 5-18). The
number of shims vary from mower to
mower. Put them next to the snap-ring.
5. Pull off pinion gear (H, Figure 5-18).
6. Remove drive pin (G, Figure 5-18).
7. Remove plastic washer/seal
(F, Figure 5-18).
8. Thoroughly clean off debris from the
drive pin, axle, hole in axle (for drive pin)
and the washer/seal.
9. Reinstall washer/seal (F, Figure 5-18).
Be sure to install flat side of washer
against bearing (mower deck).
10. Insert the drive pin (G, Figures 5-18)
into the hole in the axle.
NOTE: The pin should slide freely within
the hole.
11. Thoroughly clean pinion gear,
including surface area and cavity.
12. Slide the pinion gear (H, Figure 5-18)
onto the axle with the cavity toward the
mower. Press the gear firmly against the
washer/seal (F, Figure 5-18). Be certain
that the gear is flush against the surface
of the washer/seal and that the
washer/seal is flush against the wheel
mounting bracket.
13. Slide the shims (I, Figure 5-18) onto
the axle and against the pinion gear. Be
sure to install the same number of shims
as were removed from the unit.
14. Install the snap-ring onto the axle
(J, Figures 5-18) and into the groove in
the axle. Pull the pinion gear outward to
be sure that the snap-ring seats properly.
NOTE: If you can’t get the snap-ring into
the slot in the axle, press the pinion gear
more firmly against the washer/seal. Do
not leave off shims.
15. Insert wheel screw (A, Figure
5-18) through wheel (B), flat washer (C),
center hole in wheel shield (D), and
spacer (E). The wheel shield has a double
edge on the rim. Position this side
toward the wheel.
16. Align pinion gear with the hole in the
wheel shield. At the same time, align the
wheel screw with the welded nut on the
wheel bracket and tighten securely.
