SECTION 4: IMPORTANT SAFE OPERATION PRACTICES
WARNING: THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF
NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF
YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL
BEFORE ATTEMPTING TO OPERATE YOUR LAWN MOWER. FAILURE TO COMPLY WITH
THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL,
HEED ITS WARNING.
WARNING: The Engine Exhaust from this product contains chemicals known to
the State of California to cause cancer, birth defects or other reproductive harm.
DANGER: Your lawn mower was built to be operated according to the rules for safe operation in
this manual. As with any type of power equipment, carelessness or error on the part of the operator
can result in serious injury. This lawn mower is capable of amputating hands and feet and throwing
objects. Failure to observe the following safety instructions could result in serious injury or death.
1. GENERAL OPERATION
• Read, understand, and follow all instructions in the
operator’s manual and on the machine before
starting. Keep this manual in a safe place for future
and regular reference and for ordering replacement
parts.
• Only allow responsible individuals familiar with the
instructions to operate the machine. Know controls
and how to stop the machine quickly.
• Do not put hands or feet under cutting deck or near
rotating parts.
• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade. A small object may have been overlooked
and could be accidentally thrown by the mower in
any direction and cause injury to you or a
bystander. To help avoid a thrown objects injury,
keep children, bystanders and helpers at least 75
feet from the mower while it is in operation. Always
wear safety glasses or safety goggles during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects. Stop
the blade(s) when crossing gravel drives, walks or
roads.
• Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
• Never carry passengers.
• Disengage blade(s) before shifting into reverse and
backing up. Always look down and behind before
and while backing.
• Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not
operate the mower without either the entire grass
catcher or the chute guard in place.
• Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
• Never leave a running machine unattended. Always
turn off blade(s), place transmission in neutral, set
park brake, stop engine and remove key before
dismounting.
• Turn off blade(s) when not mowing.
• Stop engine and wait until blade(s) comes to a
complete stop before (a) removing grass catcher or
unclogging chute, or (b) making any repairs,
adjusting or removing any grass or debris.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the
influence of alcohol or drugs.
• Watch for traffic when operating near or crossing
roadways.
• Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over,
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.
• Never make a cutting height adjustment while
engine is running if operator must dismount to do
so.
• Wear sturdy, rough-soled work shoes and close-
fitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals, or
sneakers.
• Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving buildings,
or in any other situation where the operator may be
struck or pulled from the unit, which could result in
serious injury.
![](asset-4.png)

• Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral
before attempting to start engine.
• Your mower is designed to cut normal residential
grass of a height no more than 10". Do not attempt
to mow through unusually tall, dry grass (e.g.,
pasture) or piles of dry leaves. Debris may build up
on the mower deck or contact the engine exhaust
presenting a potential fire hazard.
2. SLOPE OPERATION
Slopes are a major factor related to loss of control and tip-
over accidents which can result in severe injury or death.
All slopes require extra caution. If you cannot back up the
slope or if you feel uneasy on it, do not mow it.
For your safety, use the slope gauge included as part of this
manual to measure slopes before operating this unit on a
sloped or hilly area. If the slope is greater than 15° as
shown on the slope gauge, do not operate this unit on that
area or serious injury could result.
DO:
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, limbs, etc.
• Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
• Use slow speed. Always keep machine in gear
when going down slopes to take advantage of
engine braking action.
• Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve
stability.
• Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
• Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed or
direction. Rapid engagement or braking could
cause the front of the machine to lift and rapidly flip
over backwards which could cause serious injury.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.
DO NOT:
• Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches or
embankments. The mower could suddenly turn
over if a wheel is over the edge of a cliff or ditch, or
if an edge caves in.
• Do not mow on wet grass. Reduced traction could
cause sliding.
• Do not try to stabilize the machine by putting your
foot on the ground.
• Do not use grass catcher on steep slopes.
3. CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that chil-
dren will remain where you last saw them.
• Keep children out of the mowing area and in
watchful care of an adult other than the operator.
• Be alert and turn machine off if children enter the
area.
• Before and when backing, look behind and down
for small children.
• Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
the safe machine operation.
• Never allow children under 14 years old to operate
the machine. Children 14 years and over should
only operate machine under close parental
supervision and proper instruction.
• Remove key when machine is unattended to
prevent unauthorized operation.
• Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
4. SERVICE
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
• Use only an approved container.
• Never remove fuel cap or add fuel with the engine
running. Allow engine to cool at least two minutes
before refueling.
• Replace fuel cap securely and wipe off any spilled
fuel before starting the engine as it may cause a
fire or explosion.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel the machine indoors because fuel
vapors will accumulate in the area.
• Never store the fuel container or machine inside
where there is an open flame or spark, such as a
gas hot water heater, space heater or furnace.
• Never run a machine inside a closed area.
• To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up oil
or fuel spillage. Allow machine to cool at least 5
minutes before storing.
• Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent
accidental starting.
• Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade for damage (e.g., excessive
wear, bent, cracked). Replace with blade which
meets original equipment specifications.
![](asset-5.png)

• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices. Check their
proper operation regularly. Use all guards as
instructed in this manual.
• After striking a foreign object, stop the engine,
remove the wire from the spark plug and thoroughly
inspect the mower for any damage. Repair the
damage before restarting and operating the mower.
• Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For
your safety protection, frequently check
components and replace with manufacturer’s
recommended parts when necessary.
• Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing blade(s).
• Check brake operation frequently. Adjust and
service as required.
• Muffler, engine and belt guards become hot during
operation and can cause a burn. Allow to cool
down before touching.
• Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
• Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can harm
the environment and the ecology.
• Prior to disposal, determine the proper method to
dispose of waste from your local Environmental
Protection Agency. Recycling centers are
established to properly dispose of materials in an
environmentally safe fashion.
• Use proper containers when draining fluids. Do not
use food or beverage containers that may mislead
someone into drinking from them. Properly dispose
of the containers immediately following the draining
of fluids.
• DO NOT pour oil or other fluids into the ground,
down a drain or into a stream, pond, lake or other
body of water. Observe Environmental Protection
Agency regulations when disposing of oil, fuel,
coolant, brake fluid, filters, batteries, tires and other
harmful waste.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons
who read, understand and follow the warnings and instructions in this manual and on the machine.

MOWING
This tractor is equipped with one of
Cub Cadet’s
high quality cutting decks. The following information
will be helpful when using the cutting deck with your
tractor.
WARNING: To avoid possible injury, do
not allow anyone in the area of the tractor
while mowing. Even if the area to be
mowed has been cleared of foreign
objects, small objects may be picked up
and discharged by the mower.
WARNING: Never direct the discharge
of material toward bystanders or allow
anyone near the machine while in
operation.
• For best results it is recommended that the
first two laps be cut with the discharge thrown
towards the center. After the first two laps,
reverse the direction to throw the discharge to
the outside for the balance of cutting. This will
give a better appearance to the lawn.
• Do not cut the grass too short. Short grass
invites weed growth and yellows quickly in dry
weather.
• Mowing should always be done with the
engine at full throttle.
• Do not mow at high ground speed, especially
if a mulch kit or grass collector is installed.
• Under heavier conditions it may be necessary
to go back over the cut area a second time to
get a clean cut.
• Do NOT attempt to mow heavy brush and
weeds and extremely tall grass. Your tractor is
designed to mow lawns, NOT clear brush.
• Keep the blades sharp and replace the blades
when worn. Refer to the MAINTENANCE
section of this manual for proper blade
sharpening instructions.
SECTION 9: ADJUSTMENTS
LEVELING THE DECK
WARNING: Cutting blades are sharp.
Always protect hands by wearing heavy
leather work gloves to grasp blades.
NOTE:
Check the tractor’s tire pressure before
performing any deck leveling adjustments. Refer to
TIRES
in the maintenance section of this manual for
further information regarding tire pressure.
Front to Rear
The front of the cutting deck is supported by a stabi-
lizer bar that can adjusted to level the deck from front
to rear. The front of the deck should be 1/4" to 3/8"
lower than the rear of the deck. Adjust if necessary
as follows:
WARNING: Turn the tractor’s engine
off, remove the key from the ignition switch
and apply the tractor’s parking brake before
making any adjustments to the cutting
deck.
• With the tractor parked on a firm, level
surface, place the lift lever in the top notch
(highest position) and rotate the blade nearest
the discharge chute so that it is parallel with
the tractor.
• Measure the distance from the front of the
blade tip to the ground and the rear of the
blade tip to the ground. The first measurement
taken should be between 1/4" and 3/8" less
than the second measurement. Determine the
approximate distance necessary for proper
adjustment and proceed, if necessary, to the
next step.
• Loosen the two jam nuts on the rear side of
the deck stabilizer bracket. See Figure 7A.
• Locate the two lock nuts on the opposite side
of the stabilizer bracket. See Figure 7A.
Tighten the lock nuts to raise the front of the
deck; loosen the lock nuts to lower the front of
the deck.
• Retighten the two jam nuts loosened earlier
when proper adjustment is achieved.
Side to Side
If the cutting deck appears to be mowing unevenly, a
side to side adjustment can be performed. Adjust if
necessary as follows:
WARNING: Turn the tractor’s engine
off, remove the key from the ignition switch
and apply the tractor’s parking brake
before making any adjustments to the
cutting deck.
• With the tractor parked on a firm, level
surface, place the lift lever in the top notch
(highest position) and rotate the both blades
so that they are perpendicular with the tractor.
![](asset-f.png)

Thread the idler adjustment rod inward or outward to
lengthen or shorten the travel of the double-idler
bracket until proper adjustment is achieved.
• Reassemble by following the above steps in
reverse order.
IMPORTANT:
After replacing the drive belts,
perform the PTO adjustment as instructed in the
ADJUSTMENTS
section of this manual prior to
operating the tractor.
CUTTING BLADES
WARNING: Cutting blades are sharp.
Always protect hands by wearing heavy
leather work gloves to grasp blades.
The blades may be removed for sharpening or
replacement as follows.
• Remove the deck from beneath the tractor,
(refer to DECK REMOVAL earlier in this
section for detailed instructions) then gently
flip the deck over to expose its underside.
• Place a block of wood between the center
deck housing baffle and the cutting blade to
act as a stabilizer. See Figure 22.
• Use a 15/16" wrench to remove the hex flange
nut that secures the blade to the spindle
assembly. See Figure 22.

NOTE:
The hex flange nut has a right-handed
thread pattern. Do NOT attempt to force the nut in
the incorrect direction. Doing so may damage the
nut and create a safety hazard.
Figure 22
To properly sharpen the cutting blades, remove
equal amounts of metal from both ends of the blades
along the cutting edges. See Figure 23.
Sharpen the cutting edge straight across, parallel to
the trailing edge, at a 25° to 30° angle. See Figure
23.
IMPORTANT:
If the cutting edge of the blade has
already been sharpened to within 5/8" of the wind
wing radius, or if any metal separation is present,
replace the blades with new ones. See Figure 23.
Figure 23
It is extremely important that each cutting blade
edge be ground equally to maintain proper blade
balance. An unbalanced blade will cause excessive
vibration when rotating at high speeds, may cause
damage to the tractor and result in personal injury.
The blade can be tested by balancing it on a round
shaft screwdriver. Grind metal from the heavy side
until it balances evenly.
When replacing the blade, be sure to install the
blade with the side of the blade marked ‘‘Bottom’’ (or
with a part number stamped in it) facing the ground
when the mower is in the operating position.
IMPORTANT:
Use a torque wrench to tighten the
blade spindle hex flange nut to between 70 foot-
pounds and 90 foot-pounds.
BATTERY
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
• Always keep the battery cables and terminals
clean and free of corrosive build-up.
• After cleaning the battery and terminals, apply
a light coat of petroleum jelly or grease to the
terminals and over the positive terminal boot.
• Always keep the boot positioned over the
positive terminal to prevent shorting.
IMPORTANT:
If removing the battery for any
reason, disconnect the NEGATIVE (Black) wire from
it’s terminal first, followed by the POSITIVE (Red)
wire. When re-installing the battery, always connect
the NEGATIVE (Black) wire its terminal first, followed
by the POSITIVE (Red) wire. Be certain that the
wires are connected to the correct terminals.
reversing them could change the polarity and cause
damage to your engine’s alternating system.
Charging
If the unit has not been put into use for an extended
period of time, charge the battery with an
automotive-type 12-volt charger for a minimum of
one hour at six amps.
WARNING: Batteries give off an
explosive gas during and for some time
after charging. Charge battery in a well
ventilated area and do not allow a spark or
an open flame near the battery.
FUSE
A fuse is installed in your tractor’s wiring harness to
protect the tractor’s electrical system from damage
caused by excessive amperage. Always use the
same capacity fuse for replacement. If the electrical
system does not function, or your tractor’s engine
will not crank, first check to be certain that the fuse
has not blown. It can be found under the hood
mounted behind the top of dash panel on the
support bar. Pull the fuse out and compare it with
Figure 24 to determine if it is good or bad.

TIRES
The recommended operating tire pressure is
approximately 10 psi for the rear tires and 14 psi for
the front tires. Refer to the tire sidewall for exact tire
manufacturer’s recommended psi. Do not
overinflate. Uneven tire pressure could cause the
cutting deck to mow unevenly.
SECTION 11: LUBRICATION
WARNING:
Always stop the engine and disconnect the spark plug wire(s) and ground against the
engine before performing any maintenance.
ENGINE
Lubricate the engine with motor oil as instructed in the separate engine manual packed with your unit.
PIVOT POINTS
Lubricate all pivot points (AutoDrive™ pedal, brake pedal, etc.) at least once a season with light oil.
LINKAGE
Lubricate all the pivot points on the drive, brake and lift linkage at least once a season with SAE 30 engine oil.
STEERING GEAR
Lubricate the teeth of the steering gear with an all-purpose automotive grease every 25 hours of operation or
once a season.
WHEELS
Both the front wheels and the rear wheels should be removed from the axles once a season. Lubricate the
axles and the rims well with an all-purpose automotive grease before re-installing them.
FRONT AXLES
Your tractor may be equipped with zerk fittings on the ends of the front pivot bar. See Figure 9. Lubricate both
the left and the right front axles with a grease gun at least once a season.

SECTION 12: TROUBLESHOOTING GUIDE
Trouble Possible
Cause(s) Corrective Action
Engine will
not crank
Safety switch
button not
depressed.
Battery installed
incorrectly.
Battery is dead
or weak.
Blown fuse
There are two safety switches in the starting circuit of your unit: the brake pedal switch
and the PTO switch. Make certain the actuator is fully depressing the buttons on each
switch. The Operator must be seated on the tractor in order to start the engine, also.
The battery must be installed with negative terminal attached to black ground wire.
Negative terminal is identified at the post by “NEG”, “N” or “-”. The positive terminal,
identified by “POS”, “P” or “+”, must be attached to the thick red wire which goes to the
solenoid.
Charge at six amps with a 12-volt automotive-type battery charger for one hour or until
fully charged.
Refer to operator’s manual for fuse location. Replace fuse with automotive type fuse of
the proper amperage. Fuses seldom fail without a reason. The problem must be
corrected. Check for loose connections in the fuse holder. Replace fuse holder if nec-
essary. A dead short may be in the cranking or charging circuit where the insulation
may have rubbed through and exposed the bare wire. Replace the wire or repair with
electrician's tape if the wire strands have not been damaged.
Note: Look for a wire pinched between body panels, burned by the exhaust pipe or
muffler or rubbed against a moving part.
Engine

control and choke for starting..
Gasoline tank empty. Fill.
Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace fuel filter
(if so equipped) if necessary.
Spark plug lead disconnected. Connect lead. Using a spark tester, check for spark. If
no spark is present, have engine’s magneto serviced by your Cub Cadet dealer.
If the air cleaner is dirty, the engine may not start. Refer to the engine manual packed
with your unit.

TWO-YEAR RESIDENTIAL
ONE-YEAR COMMERCIAL
Proper maintenance of your Cadet equipment is the owner’s responsibility. Follow the instructions in your

complete line of quality lubricants and filters for your equipment’s engine, transmission, chassis and
attachments.
Riding mowers, lawn tractors, Cadet

This limited warranty for residential users, covers any defect in materials or workmanship in your Cadet

Batteries have a one-year prorated limited warranty with 100% replacement during the first three months.
V-belts for either the traction drive or any attachments are covered for one year only.
Cadet equipment used commercially is warranted for one year only.
(Commercial use is defined as either having hired operators or used for income producing purposes.)

The warranty does not cover routine maintenance items such as lubricants, filters (oil, fuel, air and hydraulic),
cleaning, tune-ups, brake and/or clutch inspection, adjustments made as part of normal maintenance, blade
sharpening, set-up, abuse, accidents and normal wear. It does not cover incidental costs such as transporting
your equipment to and from the dealer, telephone charges or renting a product temporarily to replace a
warranted product.
There is no other express warranty.
How to obtain service
Contact your authorized Cub Cadet servicing dealer who sold you your Cadet equipment. If this dealer is not
