1. SAFETY PRECAUTIONS
3. Precautions before Operating Your Tractor
5. Check overhead clearance carefully before
driving under power lines, wires, bridges or low
hanging tree branches, before entering or leaving
building, or in any other situation where the
operator and/or Roll-Over Protective Structure
(ROPS) may be struck, which could result in
serious injury.
6. Make sure that any person (other than a usual
operator) who will operate the tractor studies this
Operator’s Manual before operation. Know the
controls and how to stop the machine quickly.
7. Make sure that any person or obstacle is not
under or around the tractor before and during
operation. Be sure to maintain sufficient
overhead clearance above the tractor.
8. Do not operate your tractor and/or implement
installed to it while you are under the influence of
alcohol, drug, medicine or controlled
substance(s) or when you are not fit for operation
of your tractor.
9. For operation, wear close-fitting clothing. When
operating the tractor or working around the
tractor, do not wear loose-fitting clothes or
jewelry, or baggy or damaged clothing. When
caught by a moving part of the tractor, an
accident can result. Cut-off pants or shorts do not
provide protection against flying debris. Never
operate the tractor in bare feet, sandals, or
sneakers. Wear additional protections including
non-slip safety boots or shoes, and safety
goggles and gloves, etc. as appropriate or
required by currently applicable local laws and
regulations. Wear ear protection in a noisy
environment to prevent hearing damage and
reduce operator fatigue.
10. NEVER allow a passenger on any portion of the
tractor.
11. Remain seated in the operator’s station when
operating the tractor.
12. Make sure that the brakes, clutch and other
mechanical components are free from
misadjustment and excessive wear. Replace any
excessively worn or damaged component
immediately. At regular intervals, check that all
the nuts, bolts and screws are appropriately
tightened. (For details, see “MAINTENANCE”)
1. Understand the performance and limitations of
your tractor. Carefully study this Operator’s
Manual and learn the instructions in it before
operating or servicing your tractor. Keep the
Operator’s Manual in an easily accessible place.
2. Strictly follow the statements given in the
DANGER, CAUTION and WARNING safety
decals attached to the tractor.
3. For operator safety, always install the Roll-Over
Protective Structure (ROPS).
Keep the seat belt fastened while operating the
tractor with the Roll-Over Protective Structure
(ROPS). This practice will reduce the possibility
of injury or death in the event of roll-over
accident.
If the Roll-Over Protective Structure (ROPS) has
been removed for any reason, be sure to reinstall
all the associated parts before operating the
tractor.
Do not alter the Roll-Over Protective Structure
(ROPS). The altered Roll-Over Protective
Structure (ROPS) may fail to provide the
designed protection.
Replace the damaged Roll-Over Protective
Structure (ROPS) immediately. Contact your
local Cub Cadet Yanmar dealer for technical
assistance.
NEVER alter or repair the Roll-Over Protective
Structure (ROPS). Welding, bending, drilling,
grinding, or cutting may weaken the Roll-Over
Protective Structure (ROPS). Contact your local
Cub Cadet Yanmar dealer for technical
assistance.
4. Always fasten the seat belt while operating the
tractor with the Roll-Over Protective Structure
(ROPS).
Check the seat belt for any damage. Replace the
damaged seat belt immediately. Contact your
local Cub Cadet Yanmar dealer for technical

Sc2400 Operator’s Manual
1. SAFETY PRECAUTIONS
15. Only use the implements that satisfy the
requirements in this manual or are approved by
your Cub Cadet Yanmar dealer. (See “4.
IMPLEMENT CAPACITIES”)
16. When using front or rear mounted implements,
install an appropriate weight(s) to the front or rear
of your tractor to prevent upsetting of the tractor.
If you choose to use the front loader, mount an
implement or ballast to the 3-point hitch in order
to get the tractor to stabilize. Observe the
instructions about safety in the manual for the
implement to be used.
17. Do not attempt to modify your tractor.
Modification can deteriorate the performance
and/or safety of your tractor, possibly leading to
personal injury or property damage.
13. Always keep your tractor clean. Dust, grease or
grass clippings accumulated on your tractor can
lead to fire accidents or personal injury.
14. Use the handholds and running board steps
when getting on and off the tractor to help prevent
accidental falls. Keep the running boards clear of
mud and debris.
4. Safe Practices for Operating Your Tractor
1. Starting Your Tractor
5. Do not run or idle the engine in a confined area
that is poorly ventilated or not ventilated at all.
The engine emits carbon monoxide gas that is
colorless, odorless and can cause death.
1. Remain seated in the operator’s station when
starting the engine, or actuating the levers or
controls. Do not start the engine or operate
controls while standing beside the tractor.
2. Before starting the engine, make sure that the
forward and reverse drive pedal are in the neutral
positions, the parking brake is engaged, and the
Power Take Off (PTO) is disengaged.
3. Always keep the seat belt fastened around your
waist whenever the tractor has the Roll-Over
Protective Structure (ROPS).
4. Start the engine of your tractor only by using the
starter key switch. Do not attempt to start the
engine by short-circuiting across the starter
solenoid terminals with a jumper wire, or by
bypassing the safety start switch. This defeats
the safety interlock circuit and the tractor may
begin to move and/or the Power Take Off (PTO)
shafts may begin to rotate, possibly leading to
personal injury or property damage.
Sc2400 Operator’s Manual
6. Before operation, check that all the safety
features are functioning correctly. Never tamper
with safety devices. Check their proper operation
regularly. Contact your Cub Cadet Yanmar dealer
if safety devices malfunction.
7. Avoid accidental contact with control pedals while
the engine is running, as this can cause
unexpected movement of the tractor.
8. Never leave a running machine unattended.

1. SAFETY PRECAUTIONS
2. Working with Your Tractor
3. Considerations for Safety of Children
1. Make sure that all the covers and guards are in
correct position. Replace any missing or
damaged cover immediately.
2. Before turning or when traveling on a rough
terrain, or before stopping, decrease the tractor
speed in order to prevent upsetting.
3. Use extra caution when operating over rough
ground, when crossing ditches or slopes, and
when turning corners.
4. Do not attempt to turn with the differential lock
engaged. Attempting to turn the tractor while the
differential lock is engaged can lead to a roll-over.
5. Stay clear of ditches, holes, embankments or
ponds. A hazard of tractor upset can occur more
easily if the ground is soft or wet. Before entering
an area covered with tall grass, walk the area to
detect any obstacles.
6. Always watch where you are going, especially at
blind corners, trees, or other objects that can
obscure your vision. Remain alert when you are
approaching the end of a row, trees or any
obstacle.
7. When two or more people are working in one
area, always keep in good communication with
each other.
8. Do not get on or off a moving tractor.
9. Make certain all tractor lights are illuminated
when operating at night.
Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the machine. They do not understand the
dangers. Never assume they will remain where you
last saw them.
1. Keep children out of the operating area and in the
watchful care of an adult other than the operator.
2. Be alert if a child enters the work area, stop your
tractor immediately.
3. Never allow a child to ride on the tractor. They
may fall off and be seriously injured or interfere
with safe machine operation.
4. Never allow children under 16 years old to
operate the machine. Children 16 years and over
should only operate machine under close
parental supervision and proper instruction.
5. Be extremely careful when backing the tractor.
Before and during backing, look back and
downward. A child may be in your path.
6. Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
7. Never allow a child to play on the tractor or
implement.
8. Keep children away from hot or running engines.
They may suffer burns.
9. Park your tractor on a solid, flat and level place.
Engage the parking brake securely, remove the
key from the starter key switch to prevent
unauthorized operation. If parking on a slope is
unavoidable, park the tractor across the slope
and chock the wheels.

Sc2400 Operator’s Manual
1. SAFETY PRECAUTIONS
5. Operating Your Tractor on Slopes
DO NOT:
On a slope, the tractor is less stable and more prone
to tip-over, possibly leading to serious injury or death.
Remain very cautious when your tractor is on any
slope.
●Do not mow near drop-offs, ditches or
embankments. The mower could suddenly turn
over if a wheel goes over the edge of a cliff or ditch,
or if an edge caves in.
WARNING
●Before approaching a slope, select an
appropriate speed setting. Be sure to run the
tractor at a lower speed on slopes.
●Suddenly starting the tractor on an uphill can
cause the front wheels to jump off the ground,
and this situation poses an extreme danger. To
avoid this problem, run the engine at a lower
speed, and gently start the tractor.
●Do not park the tractor on a slope. If parking on
a slope is unavoidable, chock the tires, and
engage the parking brake securely.
A2019005
DO:
●Operate 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
such obstacles.
●Place the transmission in the slow range when
climbing or descending slopes.
●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 Power Take Off (PTO) and
proceed slowly straight down the slope.
●To avoid upset, move backward up a steep slope.
If backing on the slope is not comfortable, do not
attempt to continue. Avoid an extremely steep
slope.
●When moving forward to escape from a ditch, or
deep mud, or when traveling on a steep slope, the
risk of the tractor upsetting backward is high.
Always move backward to escape these situations.
In the four-wheel drive mode, special caution is
needed to avoid false confidence in the tractor’s
ability to climb slopes.
Sc2400 Operator’s Manual

1. SAFETY PRECAUTIONS
6. Traveling on a Road
7. Always travel at a speed that allows you to
maintain control of the tractor.
8. Avoid engaging differential lock while traveling on
a road. It may cause the operator to lose control
of the tractor.
9. While traveling on a road, do not suddenly turn
the steering wheel. Such an action can lead to
loss in the stability of the tractor, and can cause
an extremely dangerous situation.
10. While on a road, do not attempt to operate an
implement. During transportation, put the 3-point
hitch control / cutting height adjustment lever in
its raised position and lock it with the position
stop knob. Do not fully close the hydraulic flow
control / stop knob.
1. Disengagement of the 4-wheel drive is
recommended.
2. Remember that the braking characteristics differ
between the two and four wheel drive modes. Be
aware of the current drive mode and use
carefully.
3. Before turning, always slow down the tractor.
High-speed turn may cause the tractor to tip over.
4. When traveling on a road, be sure that the Slow
Moving Vehicle (SMV) emblem is on the tractor
and is clearly visible. Use the hazard lights and
turn lights as required by the currently effective
local laws or regulations.
5. Strictly observe all the currently effective local
traffic and safety laws and regulations.
6. Turn ON the headlights as required by the
currently effective local laws or regulations.
7. Safe Practices for Parking Your Tractor
3. Do not park on a steep slope. Rather, park on
solid, flat, level ground whenever possible. If
parking on a slope is unavoidable, park the
tractor across the slope, and lower the implement
to the ground and chock the wheels.
4. Allow the tractor to cool at least 5 minutes before
storing.
1. Disengage the Power Take Off (PTO), lower the
implement to the ground, set the forward and
reverse drive pedal in the neutral positions,
engage the parking brake securely, stop the
engine and remove the key from the starter key
switch.
2. Before leaving your tractor, be sure the tractor is
completely stopped.

Sc2400 Operator’s Manual
1. SAFETY PRECAUTIONS
8. Operating the Power Take Off (PTO)
3. Before installing or operating Power Take Off
(PTO)-driven implement, carefully study the
manufacturer’s Operator’s Manual and the safety
decals on the implement.
4. When installing the Power Take Off (PTO)- driven
implements, engage the parking brake securely
and chock the four wheels. Do not approach or
access any rotating component.
1. Before getting off the tractor, connecting/
disconnecting an implement, adjusting, cleaning
or servicing a Power Take Off (PTO)-driven
implement, make sure that all the moving
components are at a standstill.
2. Ensure that the Power Take Off (PTO) shaft
cover is always in place. Replace the Power Take
Off (PTO) shaft cap only when the shaft is at a
standstill.
9. Using the 3-Point Hitch
2. Before using a 3-point hitch mounted implement,
the appropriate counterbalance may need to be
installed on the front of the tractor.
1. Use the 3-point hitch only in conjunction with the
implement that is specifically designed for use
with the 3-point hitch.
10. Safety Frame (Roll-Over Protective Structure) (ROPS) Precautions
4. Never attach ropes, chains, or cables to the RollOver Protective Structure (ROPS) for pulling
purposes.
5. Although the Roll-Over Protective Structure
(ROPS) provides the operator the maximum
protection possible, never take unnecessary
risks.
Your tractor is equipped with a Roll-Over Protective
Structure (ROPS) which must be maintained in a fully
functional condition. Check overhead clearance
carefully before driving under power lines, wires,
bridges or low hanging branches, before entering or
leaving buildings, or in any other situation where the
operator and/or Roll-Over Protective Structure
(ROPS) may be stuck, which could result in serious
injury.
1. Never modify the Roll-Over Protective Structure
(ROPS) in any way.
2. Never attempt to straighten or reweld any part of
the main frame or retaining brackets that have
been damaged. Doing so may weaken the
structure and endanger your safety.
3. Never secure any parts on the main frame or
attach the safety frame with anything other than
the special fasteners specified.
Sc2400 Operator’s Manual

1. SAFETY PRECAUTIONS
11. Safe Practices for Servicing Your Tractor
9. Prior to “jump starting” a tractor that has a fully
depleted battery, read and follow all the
instructions in the “7. OPERATING THE
ENGINE”.
10. Carefully loosen the radiator cap to the first stop,
and allow excessive pressure to escape, and only
then remove the radiator cap. If the tractor is
equipped with a coolant reserve tank, add coolant
or water to the reserve tank, not to the radiator
(See “Checking the Cooling System”).
Before starting any servicing work, park your tractor
on solid, level ground, engage the parking brake
securely, disengage the Power Take Off (PTO),
lower the implement to the ground, set the forward
and reverse drive pedal to the neutral position, stop
the engine and remove the key from the starter key
switch.
1. Always keep a first-aid kit and a fire extinguisher
readily available.
2. Before accessing the engine, muffler, radiator or
other possibly hot components, wait until the
tractor has fully cooled off.
11. Before working on or around electric
components, first disconnect the battery ground
cable.
12. To prevent a spark occurring from short-circuit,
disconnect the battery grounding (–) terminal first
and reconnect last.
3. Use extreme care in handling diesel fuels. They
are extremely flammable and the vapors are
explosive. Use only an approved container.
4. Be sure to stop the engine before refueling. After
refueling, replace fuel cap securely and wipe off
any spilled fuel before starting the engine as it
may cause a fire or explosion.
5. Do not smoke while refueling. Keep any spark or
open flame away from the fuel tank.
6. Never refuel the machine indoors because fuel
vapors will accumulate in the area.
7. 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.
8. Do not smoke while working around the battery.
Keep any spark or open flame away from the
battery. The battery emits hydrogen and oxygen
gas, in particular, during recharging and can pose
a hazard of explosion.
13. The operator must not mount a tire onto a rim.
Only qualified personnel should do this task.
14. Always keep the tires at a correct pressure level.
Do not exceed the recommended tire pressure
specified in the Operator’s Manual.
15. Keep the tractor securely supported while
changing the wheels or adjusting the wheel tread
width. Be sure to tighten the wheel bolts at the
specified tightening torque.
1-9
Sc2400 Operator’s Manual
1. SAFETY PRECAUTIONS
19. Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
20. Observe proper disposal laws and regulations.
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.
21. 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.
22. 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.
23. We do not recommend the use of a pressure
washer or garden hose to clean your unit. They
may cause damage to electrical components;
spindles; pulleys; bearings; or the engine. The
use of water will result in shortened life and
reduce serviceability.
16. Avoid working under any hydraulically supported
devices. Such devices can settle, suddenly leak
down, or be accidentally lowered. If working
beneath the tractor, or an implement, is
unavoidable, be sure to support the tractor or
implement with appropriate stands or lift
apparatus.
17. High pressure hydraulic fluid, when released, can
penetrate human skin, possibly leading to serious
personal injury. Before disconnecting any
hydraulic line, fully release the internal pressure.
Before exerting a pressure to the hydraulic
system, make sure that all connections are tight
and all the lines, pipes and hoses are free from
fissure/crack or any other damage.
18. Check brake operation frequently. Adjust and
service as required.
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.

1. SAFETY PRECAUTIONS
12. Understanding the Tractor Safety Decals
■ Safety-Alert Symbols
The tractor safety decals illustrated in this section are
provided in critical areas on the tractor so that people
including the operator can remain always aware of
potential hazards.
The tractor safety decals contain the words DANGER,
WARNING and CAUTION together with the safety-alert
symbols. DANGER and WARNING stand for the most
serious hazards.
The Operator’s Manual also contains special safety
messages that explain potential hazards about which the
operator must remain cautious. These messages are
presented together with the word CAUTION and the
safety-alert symbols.
■ Care of DANGER, WARNING and CAUTION
Decals
1. Always keep all the danger, warning and caution
decals clean and clearly legible.
2. Clean the danger, warning and caution decals with
soap water, and wipe dry with clean soft cloth.
3. Replace damaged or missing danger, warning and
caution decals with new decals available from your
local Cub Cadet Yanmar dealer.
4. If a component having a danger, warning or caution
decals is replaced with a new one, make sure that a
new decal is on the same location as on the old
component.
5. Affix a new danger, warning or caution decals flat on a
clean, dry surface, squeezing out trapped air.

WARNING
Accident Hazard
ALWAYS decrease tractor speed before turning,
when traveling on a rough terrain or before stopping
to prevent roll-over.
ALWAYS remain alert to behaviors of children when
operating the tractor because they are usually very
curious about moving machines.
Do not attempt to turn with the differential lock
engaged. Attempting to turn the tractor while the
differential lock is engaged can lead to a roll-over.
ALWAYS remember that children may have moved
from a point you last viewed them.
ALWAYS stay clear of ditches, holes, embankments
or ponds. A roll-over can occur more easily if the
ground is soft or wet. Before entering an area
covered with tall grass, walk the area to detect any
obstacles.
ALWAYS keep children off the work area, and a
person other than the operator should always watch
them.
If any child enters the current work area, stop your
tractor immediately.
ALWAYS be extremely careful about the direction
you are traveling and avoid obstacles. Remain alert
when you are approaching the end of a row, trees or
any obstacle.
NEVER allow children to ride the moving tractor.
They may tamper the controls or can fall off the
tractor and be run over by the tractor.
ALWAYS maintain good communication with all
others working the same area before and during
operation of the tractor.
NEVER allow children to operate the tractor.
NEVER allow children to play on the tractor or
implement.
Do not get in or out of the moving tractor.
ALWAYS be extremely careful when backing the
tractor up. Before backing up, look back and below
the tractor. Children may be on your path.

Sc2400 Operator’s Manual
8. OPERATING THE TRACTOR
1. Operating a New Tractor
The service life of the tractor is governed by how
adequately it is handled and maintained.
Of course, any newly manufactured tractor has been
tested; however, various parts must be broken in.
Therefore, operate the tractor at low speeds for the
first 50 operating hours, and avoid heavy work or
operation before the various parts have been
sufficiently run. The manner the tractor is operated in
during the breaking-in period greatly affects the
effective life of the tractor. Therefore, to develop
maximum design performance and attain the longest
life of the tractor, the tractor needs to be correctly
broken in. Handle the new tractor, strictly observing
the following instructions.
1. Do not run the tractor at full speed
during the first 50 operating hours period
●NEVER suddenly start or brake.
●In cold weather, ALWAYS fully warm up the
engine. After warm-up, start operation of the
tractor.
●NEVER run the engine at a speed higher than
needed.
●On rough roads or terrains, slow the tractor down
as necessary. Do not run the tractor at a high
speed.
The above-mentioned precautions apply not only to
newly manufactured tractors but also to tractors that
have been actively used. Nevertheless, we
recommend that newly manufactured tractors be
operated by strictly observing these instructions /
recommendations.
2. Changing the lubricating oil for the new tractor
The quality of the lubricating oil in any new tractors is
very important. Various parts on a new tractor have
not been fully broken in, and are not fully fitted with
each other. As a result, small metal shavings may
occur while the new tractor is operated, and may
lead to premature wear or damage of the associated
parts or components. Therefore, Cub Cadet Yanmar
recommends that the lubricating oil be changed
earlier than in the ordinary oil change schedule.
For the recommended oil change schedule, refer to
the “13. MAINTENANCE”.

implement. Keep the 3-point hitch in the raised
position during transport.
3. Moving the Tractor Manually while the Engine is Stopped
WARNING
Avoid injury:
Setting the Hydro Static Transmission (HST)
pressure release lever to the ON position makes
the tractor freely move.
●Do not operate the Hydro Static Transmission
(HST) pressure release lever on a slope. Setting
the Hydro Static Transmission (HST) pressure
release lever to the ON position on the slope
makes the axles freely move, so that the tractor
will be out of control.
●Before setting the Hydro Static Transmission

8. OPERATING THE TRACTOR
5. Operating on Slopes
WARNING
Avoid injury. Be extremely cautious when driving
the tractor on a slope:
●To increase the traction power and provide 4wheel braking feature, engage the 4-wheel
drive lever before driving the tractor on a slope.
Remember that although the 4-wheel drive
lever greatly assists in approach to a steep
slope, there is greater possibility of a tip over.
●To improve braking power on sloped, frozen,
wet or graveled surfaces, engage the 4-wheel
drive lever. Add ballast to the tractor as
necessary and travel at a lower speed to
prevent skidding and loss of steering control.
●While driving the tractor, do not attempt to
climb a slope that is steeper than 11 degrees.
●Even on a slope that is not steeper than 11
degrees, do not turn or change the traveling
direction, or park square to the slope.
WARNING
●Before approaching a slope, select an
appropriate speed setting. NEVER shift on a
slope. Be sure to travel at a lower speed on a
slope.
●Suddenly starting the tractor on an uphill can
cause the front wheels to jump off the ground,
and this situation poses an extreme danger. To
avoid this problem, run the engine at a lower
speed and slowly start the tractor in motion.
●NEVER park the tractor on a slope. If parking on
a slope is unavoidable, chock the tires, and pull
the parking brake lever to engage the parking
brake securely.
●On a slope, the tractor is unstable and more
prone to tip-over, possibly leading to severe
injury or even death. Remain very cautious when
your tractor is on any slope.
●To avoid tip over, move backward on a steep
slope. If backing on the slope is not comfortable,
do not attempt to continue. Avoid an extremely
steep slope.
●When exiting a ditch, deep mud or traveling on
a steep slope, the risk of the tractor roll-over is
high. In four-wheel drive mode, special caution
is needed.
●Slowly move on any slope. NEVER change
speed or direction quickly.
●When backing up a slope, keep the tractor
parallel with the gradient of the slope.

WARNING
●ALWAYS keep the tires inflated to the correct
pressure. NEVER exceed the recommended
inflation pressure specified in this Operator's
Manual.
Inflation pressure gradually reduces as time elapses.
Check the pressure of each tire before starting the
day's operation and inflate the tires as necessary to
the recommended pressures. If the tire pressures
significantly decrease though the tires are correctly
inflated every day, immediately request your local
Cub Cadet Yanmar dealer to inspect or replace the
problem tire(s).
Before loader work, make sure to check the tire
pressure and, if necessary, inflate the tire(s) to the
recommended pressure.
For the appropriate inflation pressure, refer to the
following table:
Inflation pressure
(psi(kgf/cm2))

■ Wheel Bolt Tightening Torque
WARNING
Avoid injury:
●ALWAYS keep the wheel bolts tightening to the
specified torque.
●With the wheel bolts loosened, do not drive the
tractor.
Before starting day’s operation, check tightening
torque of each of the tire wheel bolts and, if
necessary, retighten to the specified torque. For the
specified torque, refer to the following table:

2. Ballast
■ Front Ballast
To mount the front ballast, the optional front weight
hitch is required.
To improve stability and traction, add ballast
indicated in the table below. (Front End Weights)
Heavy pulling and rear-mounted implements can
cause the front wheels to lift. To cope with this
situation, add ballast so that reliable steering control
is maintained and tip-over of the tractor is prevented.
Remove the ballast when no longer necessary.
NOTE:
●For information about the optional front weight
hitch, contact your local Cub Cadet Yanmar dealer.
Front End Weights (Option)
The front end weights can be mounted to the optional
front weight hitch. For the appropriate number of
weights, see the table below.

■ Maximum Weight
WARNING
●NEVER overload the tires.
●NEVER add weight in excess of the limits
indicated below.
Four 44 lb (20 kg) weights can be added to the tractor.
■ Using Liquid Weight for the Tires
WARNING
Avoid injury:
●Installation of liquid ballast requires special
implement and training. An exploding tire can
lead to injury. Contact your local Cub Cadet
Yanmar dealer or a tire service store to do this
task.
●When using the front loader, always put liquid
weight in the rear wheels. Failure to do so may
result in overturning.
IMPORTANT: Avoid damage.
●NEVER exceed the maximum load ratings
indicated on the tires.
●ALWAYS cover rim completely with the liquid to
prevent corrosion, but do not exceed 75%. A larger
amount of the liquid causes a limited air space to
be left in the tire, and which is too small to absorb
shocks, possibly leading to damaged tire.
NOTE:
●We do not recommend that alcohol be used as the
ballast. Calcium chloride solution is heavier and
less expensive.
●A water solution of calcium chloride offers a safe,
economical ballast, and will prevent freezing. If
properly used, it will not damage tires, tubes or
rims.
●A mixture of 3.5 lb of calcium chloride and
approximately 1 US gal of water (0.4 kg/L) will not
fully freeze at a temperature above –50°F (–45°C).
●Fill tubeless tires at least to the valve stem height
(at least 75%). Smaller amount of the solution
results in partly exposed rims, possibly leading to
corrosion of the rim.

WARNING
ALWAYS allow the tractor to fully cool down before
accessing the engine, muffler, radiator or other hot
components.
NEVER smoke around the battery or
during refueling. Keep sparks or open
flames away from the battery and fuel
tank. The battery emits hydrogen and
oxygen during recharging and can pose
a serious hazard.
ALWAYS park your tractor on a solid, level ground,
engage the parking brake securely, turn off the
Power Take Off (PTO) switch, lower the implement to
the ground, set the forward and reverse drive pedal
to the neutral position, stop the engine and remove
the key from the starter key switch before starting
any service work.
NEVER work under any hydraulically supported
devices. Such devices can settle, suddenly leak or
be accidentally lowered. ALWAYS support the tractor
securely with rugged stands or other appropriate
means.
■ Warranty and Repair of the Engine
A maintenance, inspection, repair or replacement
service of engine emission control devices and
systems may be performed at the owner’s expense
by any qualified off-road engine repair shop or
mechanic. Warranty repairs must be executed by an
authorized Cub Cadet Yanmar dealer.
WARNING
NEVER inhale the emission gas.
Avoid personal injury:
●Engine emission gas contains carbon monoxide
that, if inhaled, can cause severe poisoning or
even death.
●NEVER run the engine in a poorly ventilated,
enclosed indoor space.
●To release the engine emission gas to an
outdoor area, connect an extension pipe to the
engine exhaust pipe.
●Allow fresh outside air to flow into the work
space to remove the engine emission gas from

2. Daily Checks
■ Refilling the Fuel Tank
IMPORTANT: Avoid damage.
●NEVER use a galvanized container to store fuel.
Diesel fuel in a galvanized container reacts with the
zinc coating in the container to generate zinc
flakes. If the fuel contains water, a zinc gel will also
occur. The zinc gel and flakes will quickly clog the
fuel filter and damage the fuel injection nozzle and
fuel pump.
Diesel fuel should comply with the following
specifications.
In cold climate, use Grade No. 1-D diesel fuel, and in
warm climate, use Grade No. 2-D diesel fuel. The
cetane number of the diesel fuel used must be 45 or
higher.
When the air temperature drops below –4°F(–20°C)
or the altitude of the work site exceeds 5000 ft (1500
m), use a diesel fuel whose cetane value is 50 or
higher.
The sulfur content must not exceed 0.5 % by volume.
Less than 0.05 % is preferred.
Bio-diesel Fuels
In the United States, non-mineral oil based fuel
resources such as RME (Rapeseed Methyl Ester)
and SOME (Soybean Methyl Ester), collectively
known as FAME (Fatty Acid Methyl Esters), are
being used as extenders for mineral oil derived diesel
fuels.
Cub Cadet Yanmer approves the use of bio-diesel
fuels that do not exceed a blend of 5 % (by volume)
of FAME with 95 % (by volume) of approved mineral
oil derived diesel fuel. Such bio-diesel fuels are
known in the market place as B5 diesel fuels.

■ Coolant
WARNING
Avoid injury:
●Fluids released under pressure from the
cooling system can cause severe burns.
Pressure build-up in the cooling system can,
when the radiator cap is removed, cause the
coolant to gush out explosively.
●Stop the engine and allow it to cool off.
●Do not remove the radiator cap before the
radiator and the engine are sufficiently cool
such that they can be touched with bare hands.
Carefully loosen the cap to the first stop to
allow the pressure to be completely released.
Only then, remove the cap completely.
[The following coolants are recommended]
• High Quality Permanent Type Antifreeze
(Ethylene Glycol with corrosion and rust inhibitor
chemicals)
Before using the coolant, study the instructions and
data on its container to be sure it is suitable for the
engine.
Use a conditioned coolant, or before use, add a
conditioner to the coolant.
Prepare the coolant by mixing 50% antifreeze with
50% distilled or deionized water, and then pour this
coolant into the radiator. This coolant is intended not
only to cool the engine but also to protect the radiator

WARNING
Avoid injury.
●ALWAYS allow radiator to cool before
removing the radiator cap. The radiator will be
hot and can cause burns. When the radiator
cap is removed, pressure build-up in the
cooling system can cause the coolant to spray
out explosively.
●ALWAYS shut the engine down and allow it to
cool.
●NEVER remove the radiator cap before the
radiator and the engine are sufficiently cool
such that they can be touched with bare hands.
●Loosen the radiator cap carefully to the first
stop, allowing excessive pressure to escape.
Only then remove the radiator cap. If the tractor
is equipped with a coolant reserve tank, add
coolant or water to the reserve tank, not to the
radiator. (See “Checking the Cooling System”

WARNING
Be careful to avoid injury:
●Remember that vapor from diesel fuel is explosive and flammable.
●The exhaust from the engine contains carbon monoxide that can
lead to carbon monoxide poisoning, possibly causing serious
illness or even death. To avoid the danger of poisoning from the
exhaust gas, NEVER run the engine in a closed building that is not
positively ventilated.
●NEVER wash the tractor while the engine is running.
●Run the engine as shortly as possible when moving the tractor into
and from the place of storage.
●When fuel is in the fuel tank, NEVER store the tractor in a building
where fuel vapor can come into contact with open flame or spark.
●Before storing the tractor indoors, allow the engine to cool off.
1. Preparing the Machine for Storage
If planning to store the tractor for a long period, follow the procedure
described below.
The procedure is intended to ensure that the tractor is readily prepared for
operation when it is removed from storage.
1. Repair any worn or damaged parts. Replace the parts as necessary.
Tighten any loose bolts and nuts.
2. Repair scratched or chipped metal surfaces to prevent rusting.
3. Remove grass clippings and debris from the tractor.
4. Clean below the deck and remove grass clippings and debris from
inside the chute and bagger.
5. Remove the ballast from the tractor.
6. Wash the tractor and apply wax to the metal and plastic surfaces.
7. Run the tractor for 5 minutes to dry the belts and pulleys.
8. Apply a light coat of clean engine oil to pivots and wear points to
prevent rusting.
9. Lubricate the grease fittings.
10. Check the tire pressure. Adjust the tire pressure slightly higher than
specified.
11. Change the engine oil and run the engine for about 5 minutes to
circulate the oil throughout the entire engine block and the internal
moving parts.
12. Lower any implement to the ground. Apply grease to
the exposed areas on the hydraulic cylinder piston
rods.

2. Preparing the Fuel and Engine for Storage
■ Fuel
If using stabilized fuel, fully fill the fuel tank with stabilized fuel.
NOTE:
●By filling the fuel tank, the amount of air remaining in the tank decreases,
and this can help prevent deterioration of the fuel in the tank.
If stabilized fuel has not been used.
1. Park the tractor safely and securely in a well-ventilated place.
NOTE:
●Assuming that this is the last time the tractor is operated for the season,
use all the fuel in the fuel tank.
2. Run the engine until all the fuel in the tank is used.
3. Turn the key to the OFF position.
IMPORTANT: Be very careful to avoid damage.
●In degraded fuel, varnish can occur and clog the fuel injector components
and adversely affect engine performance.
●Mix stabilizer into fresh fuel before filling the fuel tank.
4. Mix fresh fuel and fuel stabilizer in a separate container.
Observe the stabilizer manufacturer's instructions for mixing.
5. Fill the fuel tank with the stabilized fuel.
6. Run the engine for several minutes to allow the fuel-stabilizer mixture to
be circulated through the fuel system.
■ Engine
If the tractor is scheduled to be stored for longer than 60 days, prepare the
engine for storage.
1. Change the engine oil and filter while the engine is still warm.
2. Service the air filter if necessary.
3. Remove dust and debris from the engine air intake screen.
4. Clean the engine and engine compartment.
IMPORTANT: Avoid damage.
●ALWAYS disengage the clutch before storing the tractor. If the clutch is
engaged for a long period, the clutch plate may develop rust, causing the
clutch not to disengage when the tractor is operated next time.

8.
Remove the battery.
Clean the battery and battery posts. Check the electrolyte level.
Close the fuel shut-off valve.
Store the battery in a cool, dry, dark place. However, the temperature of
that place must not become low enough to freeze the electrolyte in
battery.
9. Store the tractor in a dry, safe place. If the tractor is stored outdoors,
protect it with a waterproof cover. Jack up the tractor and place blocks
under the front and rear axles to allow the tires to be lifted off the
ground. Do not allow the tires to be exposed to direct sunlight or
extremely high temperature.
