part of the operator can result in injury. This lawn mower is capable of amputating
hands and feet or throwing objects. Failure to observe the following safety
instructions could result in serious injury or death.
SAFE OPERATION PRACTICES
4. Clear the area of objects such as rocks, toys, wire,
etc. which could be picked up and thrown by the
blades. 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, animals, bystanders and helpers at
least 75 feet from the mower while it is in
operation. Always wear safety glasses with side
shields or safety goggles during operation or while
performing an adjustment or repair, to protect eyes
from foreign objects. Stop the blades when
crossing gravel drives, walks or roads.
2
5. Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
6. Never carry passengers.
7. Disengage the blades before shifting into reverse
and backing up. Always look down and behind
before and while backing.
8. 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.
9. Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
10. Never leave a running machine unattended.
Always turn off the blades, place the transmission
in neutral, set the parking brake, stop the engine
and remove key before dismounting.
11. Turn off blades when not mowing.
12. Stop the engine and wait until the blades come to
a complete stop before (a) removing the grass
catcher or unclogging chute, or (b) making any
repairs, adjusting or removing any grass or debris.
13. Mow only in daylight or good artificial light.
14. Do not operate the machine while under the
influence of alcohol or drugs.
15. Watch for traffic when operating near or crossing
roadways.
16. 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.
17. Never make a cutting height adjustment while the
engine is running if the operator must dismount to
do so.
18. Wear sturdy, rough-soled work shoes and closefitting 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.
19. 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.
20. Disengage all attachment clutches, thoroughly
depress the brake pedal and shift into neutral
before attempting to start the engine.
21. 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.
22. Use only accessories approved for this machine
by Cub Cadet. Read, understand and follow all
instructions provided with the approved
accessory.
II. 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. Exercise extreme caution when changing directions on slopes.
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. Choose a low enough gear so that
you will not have to stop or shift while on the slope. Always keep the 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 the tires lose
traction, disengage the blades 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.
3
Do not try to stabilize the machine by putting your foot
on the ground.
Do not use the grass catcher on steep slopes.
Do not tow heavy pull behind attachments (e.g. loaded
dump cart, lawn roller) on slopes greater than 5 degrees. When going downhill, the extra weight may
cause you to loose control and possibly overturn the
tractor.
d. Extinguish all cigarettes, cigars, pipes and oth-
er sources of ignition.
e. Never refuel the machine indoors because fuel
vapors will accumulate in the area.
f. 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.
III. 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.
They do not understand the dangers. Never assume
that children will remain where you last saw them.
1. Keep children out of the mowing area and in
watchful care of an adult other than the operator.
2. Be alert and turn the machine off if children enter
the area.
3. Before and when backing up, look behind and
down for small children.
4. Never carry children, even with the blades off.
Children may fall off and be seriously injured or
may interfere with safe machine operation.
5. Use extreme care when approaching blind
corners, doorways, shrubs, trees or other objects
that may block your vision of a child who may run
into the machine.
6. To avoid back-over accidents, always disengage
the cutting blades before shifting in reverse. The
"Reverse Caution Mode" should not be used
when children or others are around.
7. Keep children away from hot or running engines.
They can suffer burns from a hot muffler.
8. Remove the key when the machine is left unattended to prevent unauthorized operation.
Never allow children under 14 years old to operate the
machine. Children 14 years and over should only operate the machine under close parental supervision and
proper instruction.
IV. SERVICE
1. Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
a. Use only an approved container.
b. Never remove fuel cap or add fuel with the en-
gine running. Allow the engine to cool at least
two minutes before refueling.
c. Replace the fuel cap securely and wipe off any
spilled fuel before starting the engine as it may
cause a fire or explosion.
2. Never run a machine inside a closed area.
3. To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up
oil or fuel spillage. Allow the machine to cool at
least 5 minutes before storing.
4. 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.
5. Check the blade and engine mounting bolts at frequent intervals for proper tightness. Also visually
inspect blades for damage (e.g., excessive wear,
bent, cracked). Replace with blades which meet
original equipment specifications.
6. Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
7. Never tamper with safety devices. Check their
proper operation regularly. Use all guards as
instructed in this manual.
8. 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.
9. 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 the
components and replace with manufacturer’s
recommended parts when necessary.
10. Mower blades are sharp and can cut. Wrap the
blades or wear gloves, and use extra caution
when servicing blades.
11. Check brake operation frequently. Adjust and
service as required.
12. Muffler, engine and belt guards become hot
during operation and can cause a burn. Allow to
cool down before touching.
13. Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
4
14. Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can
harm the environment and the ecology.
a. Prior to disposal, contact your local
Environmental Protection Agency to
determine the proper method for disposing of
the waste. Recycling centers are established
to properly dispose of materials in an
environmentally safe fashion.
b. 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.
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.
c. 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.
15. With the exception of utilizing the deck wash
feature, we do not recommend the use of a
pressure washer or garden hose to clean your
tractor. Water may cause damage to electrical
components; pulleys; bearings; or the engine.
The use of water will result in shortened life and
reduce serviceability.

SECTION III. ADJUSTMENTS
DECK LEVELING ADJUSTMENTS
In order to achieve even cutting, the mower deck must
be properly leveled. This leveling procedure will result in
the left and right blades having corresponding cuttingedge-to ground measurements within 1/16 inch of each
other. Also, the blades will each have a 1/8 to 1/4 inch
downward tilt toward the front of the tractor. To level the
mower deck, proceed as follows:
WARNING
Before making any adjustments, place the PTO
switch in the “OFF” position, engage the parking
brake lever, and turn the ignition key to the “OFF”
position. When adjusting the mower deck, be
careful not to cut yourself on the sharp blades.
SIDE TO SIDE LEVELING ADJUSTMENT
NOTE: Check for proper tire inflation before checking
and/or making a leveling adjustment.
1. Position the tractor on a hard, level surface, and
use the tractor hydraulic lift system to raise the
deck to its highest position. Stop engine.
2. Carefully rotate the outer cutting blades so that
they are positioned perpendicular to the tractor
frame (See Figure 16).

3. Measure and record the distance from the surface to the outer-most cutting edge of the right
blade (See Figure 17). Repeat this step for the left
blade. If the two blade heights are not within 1/16
inch, the deck must be leveled. Note whether the
left blade had the larger or smaller distance be-
tween the cutting edge and level surface. If the
two blade heights are within 1/16 inch, proceed to
FRONT TO BACK LEVELING.
Figure 18
5. Turn the hex lock nut upward (tighten) on the
threads of the lift rod to raise the left side of the
mower deck. Turn the lock nut down (loosen) on
the lift rod threads to lower the left side of the
mower deck.
6. Recheck the measurements described in step 3.
If the blade measurements are not within 1/16
inch, repeat steps 3 and 5 until the correct measurement is obtained.
FRONT TO BACK LEVELING
The front lift rod must be correctly adjusted to maintain
the proper pitch of the deck when mowing uneven terrain.
1. Position the mower blades so the ends of each
blade point to the front and the rear of the tractor
(Refer to Figure 19).

nuts clockwise to raise the front of the deck, or
counterclockwise to lower the front of the deck.
• Recheck the measurements described in step 2
and readjust the hex lock nuts until the proper
measurements are obtained.
NOTE: The front lift rod should be fully to the front of
both slots in the deck front roller bracket. If one side of
the rod does not contact the front of the slot, tighten the
corresponding lock nut as needed.
GAUGE WHEEL ADJUSTMENT
WARNING
Before making any adjustments, place the PTO
switch in the “OFF” position, engage the parking
brakea, turn the ignition key to the “OFF”
position, and remove the key from the switch.
When handling the mower deck, be careful not
to cut yourself on the sharp blades.
NOTE
Gauge wheel adjustment should be performed
only AFTER the mower deck has been properly
leveled.
Gauge wheels are intended to prevent scalping of the
lawn, and are not to be used to set the cutting height.
The gauge wheels should be approximately 1/2" above
the ground when the deck is set in the desired cutting
height. Do not run the deck on the gauge wheels.
To adjust the height of the gauge wheels, place the
tractor on a firm and level surface. Refer to Figure 22,
and proceed as follows:
1. Use the tractor lift system to lower the deck to the
normally desired mowing height setting, then stop
the engine.
2. Remove the gauge wheels by removing the lock
nuts and shoulder screws.

USING HEIGHT ADJUSTMENT KNOB
NOTE
Tractors built Mfg. Code 1K060G and after are
equipped with a height adjustment knob which
can be used to set the downstop position of the
mower deck.
A full rotation of the height adjustment knob equals approx. a 1/4 inch adjustment in the deck height setting.
There are four detent positions per rotation. Initially set
the deck downstop as follows (See Figure 23):
1. To remove the weight of the deck from the downstop arm, use the tractor lift system to raise the
deck.
2. Fully lower the deckstop by continuously turning
the height adjustment knob counterclockwise.
3. Use the tractor lift system to lower the deck to the
desired height setting, then turn the adjustment
knob clockwise until it stops turning freely. Turn
the knob to nearest detent position.
LOWER
4. Reposition the gauge wheels so that they are
appoximately 1/2 inch above the ground.
5. For subsequent minor adjustments from this position, use the tractor lift system to raise the deck,
then turn the adjustment knob as necessary to attain the desired height setting (one full turn equals
approximately 1/4").

SECTION IV. MAINTENANCE
CLEANING THE DECK
Using The Deck Wash System
WARNING
When using the deck wash system, never
engage the deck from any position other than
the operator’s seat of the tractor. Do not use an
assistant or engage deck in the presence of any
bystanders.
1. Attach the nozzle adapter to a standard garden
hose connected to a water supply.
2. Move the tractor to an area within reach of the
hose where the dispersal of wet grass clippings is
not objectionable to you. Disengage the PTO,
engage the parking brake, and stop the engine.
3. Pull back the lock collar of the nozzle adapter and
push the adapter onto one of the deck wash
nozzles at either end of the mower deck. Release
the lock collar to lock the adapter on the nozzle.
See Figure 24.

Once a month remove the spindle covers (Refer to Figure 29) to remove any accumulated grass clippings
from around the spindle pulleys and V-belt. Service
more often when mowing tall, dry grass.
BLADE CARE
WARNING
Before performing any maintenance, place the
PTO switch in the “OFF” position, engage the
parking brake, turn the ignition key to the “OFF”
position and remove the key from the switch.
When servicing the mower deck, be careful not
to cut yourself on the sharpened blades.
The cutting blades must be kept sharp at all times.
Sharpen the cutting edges of the blades evenly so that
the blades remain balanced and the same angle of
sharpness is maintained. If the cutting edge of a blade
has been sharpened to within 5/8 inch of the wind wing
radius (See Figure 25), it is recommended that new
blades be installed.

4. Turn on the water supply.
5. From the tractor operator’s seat, start the engine
and engage the PTO. Allow to run as needed.
Disengage the PTO and stop the engine.
6. Turn off the water supply.
7. Pull back the lock collar of the nozzle adapter to
disconnect the adapter from the nozzle.
8. Repeat the previous steps to clean the deck using
the nozzle at the other end of the deck.
Clean the underside of the mower deck at the end of the
mowing season or when buildup of cut material on the
underside is noticed.
Figure 25
Use a 1-1/8 inch wrench to hold the head of the spindle bolt while loosening the hex nut securing the
blade. NOTE: A block of wood may be placed be-
tween the deck housing and cutting edge of the blade
to assist in removal of the hex nut (See Figure 26).

When reinstalling the blades, be sure they are installed
so that the wind wings are pointing upward toward the
top of the deck. Tighten the nuts to 90 to 110 ft-lbs. (122
to 149 N·m).
After replacing the blades, apply grease to the exposed
threads at the bottom of the spindles to prevent rust
buildup.
LUBRICATION
After every 10 hours of operation and/or before putting
the deck into winter storage, lubricate the spindle as-
semblies and the spindle belt idler arm with 251H EP
grease or an equivalent No. 2 multipurpose lithium
grease. The lube fitting for the outer spindles can be accessed by removing the button plugs in the belt covers.
Use grease liberally. Excess grease will be expelled
from the inverted upper seals of the spindle assemblies.
Listen for the muffled crackling noise of grease being
expelled through the seal to indicate the spindle assembly is fully greased (Refer to Figure 29).
Apply grease to all other lube fittings after every 50
hours of operation. Refer to LUBRICATION GUIDE.

SPINDLE BELT REPLACEMENT
A worn spindle belt will affect the cut quality of the
mower deck and should be replaced. Referring to Figure 27 and Figure 28, replace the spindle belt as follows:
REMOVE SPINDLE BELT
1. Remove the hex washer head screws securing the
spindle covers to the deck housing. (See Figure
27).
NOTE
Note the routing of the spindle belt to help
ensure proper installation of the new belt.
2. Insert a 3/8” drive ratchet into the square hole of
the idler bracket (Refer to Figure 28).
3. Using the ratchet for leverage, pivot the idler
bracket toward the left side of the deck to loosen
tension on the spindle belt; then roll the belt off
the right hand spindle pulley.
4. Slide the belt off the LH spindle pulley; the fixed
flat idler pulley; and the center spindle pulley.
5. Slide the belt underneath the movable flat idler
pulley on the idler bracket.
6. Remove the four sets of fasteners securing the
gear box mounting bracket to the deck mounting
plate. Refer to Figure 28.
7. Lift the gear box/ mounting bracket assembly and
slide the belt off and underneath the drive pulley.
8. Remove the belt from the deck.

LUBRICATION GUIDE
The life of any machine depends upon the care it is given. Proper lubrication is a very important part
of that care.
Be certain that all lubrication fittings are assembled in
place, using the lubrication illustration as a guide.
Always lubricate the deck thoroughly before taking it to
the field. Use a pressure lubricating gun.
Be sure all fittings are free from dirt and paint so the lubricant is certain to enter the bearing.
Miscellaneous working parts not provided with lubrication fittings should be oiled daily with a good grade of lubricating oil.
Lubricant is cheap. Use plenty of it. Worn parts can be
expensive to replace.
Keep your supply of lubricating oil and grease stored in
clean containers, and covered to protect from dust and
dirt.

Keep the lubricating gun nozzle clean and wipe dirt from
the grease fittings before lubricating.
The symbols in the illustrations indicate the method of
application and the hourly intervals to apply the lubricant.
Use a pressure lubricating gun and
apply 251H EP grease (or equivalent No. 2 multi-purpose lithium
grease) sufficient to flush out the
old grease and dirt. Lubricate at
the hourly intervals indicated on
the symbols.
