1. SAFETY PRECAUTIONS

3. Precautions before Operating Your Tractor

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 assistance. Do not use the seat belt if the tractor does not have the Roll-Over Protective Structure (ROPS).

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”)

1-3

Sc2400 Operator’s Manual

1. SAFETY PRECAUTIONS

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.

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.

4. Safe Practices for Operating Your Tractor

1. Starting Your Tractor

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.

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.

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.

Sc2400 Operator’s Manual

1. SAFETY PRECAUTIONS

2. Working with Your Tractor

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.

3. Considerations for Safety of Children

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

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.

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.

DO NOT:

●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.

6. Traveling on a Road

1. SAFETY PRECAUTIONS

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.

8. Operating the Power Take Off (PTO)

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

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. Use the 3-point hitch only in conjunction with the implement that is specifically designed for use with 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.

10. Safety Frame (Roll-Over Protective Structure) (ROPS) Precautions

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.

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.

1. SAFETY PRECAUTIONS

11. Safe Practices for Servicing Your Tractor

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.

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.

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”).

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.

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.

Sc2400 Operator’s Manual

1. SAFETY PRECAUTIONS

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.

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.

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.

8. OPERATING THE TRACTOR

WARNING

ALWAYS decrease tractor speed before turning, when traveling on a rough terrain or before stopping to prevent roll-over.

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 remain alert to behaviors of children when operating the tractor because they are usually very curious about moving machines.

ALWAYS remember that children may have moved from a point you last viewed them.

Accident Hazard

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 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.

ALWAYS maintain good communication with all others working the same area before and during operation of the tractor.

Do not get in or out of the moving tractor.

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.

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.

NEVER allow children to operate the tractor.

NEVER allow children to play on the tractor or implement.

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”.

2. Safely Driving the Tractor on Roads

WARNING

Avoid injury. Be cautious when driving the tractor at a transport speed:

●We recommend that the user / operator use the turn signal / hazard lights when traveling on public roads. Before operating the tractor on a public roadway, be aware of relevant state or local regulations in effect. An implement safety lighting kit is available from your local Cub Cadet Yanmar dealer.

●If local laws permit road travel, flash the hazard lights and display the Slow Moving Vehicle (SMV) emblems when traveling on public roadways.

When operating the tractor on a road, strictly observe the following precautions:

●ALWAYS ensure that the Slow Moving Vehicle (SMV) emblem and hazard lights are clean and clearly visible. If a towed or rear-mounted implement jeopardizes visibility of these safety devices, install the Slow Moving Vehicle (SMV) emblem and hazard lights on the implement.

(A) Typical example of installed Slow Moving

Vehicle (SMV) emblem

●Turn the hazard lights and headlights ON, unless prohibited by law.

●Drive the tractor slowly so that the tractor is under control at all times. Slow down for travel on a slope, rough road, sharp turns or when transporting a heavy rear-mounted implement.

●Disengage the 4-wheel drive to prevent excessive tire wear.

●NEVER coast downhill.

●Check whether the front wheel gearing is engaged.

●Remember that the braking characteristics differ

between the 2- and 4-wheel drive modes. ALWAYS be aware of the current drive mode and use properly.

●ALWAYS slow down before turning. High-speed turns may cause the tractor to tip over.

●Strictly observe all the currently effective local traffic and safety laws and regulations.

●ALWAYS travel at a speed that allows the tractor to remain controlled and stable.

●Avoid engaging differential lock while traveling on a road. Your tractor can lose control.

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.

6. About the Power Steering

WARNING

●NEVER operate the steering wheel suddenly, especially while traveling on a paved road. Otherwise, an accident can occur.

The power steering feature is operative only when the engine is running. Note that when the engine is running at a lower speed, the steering wheel will need slightly greater force. This is considered normal operation.

IMPORTANT:

●Fully turning the steering wheel will cause the relief valve to trip and an audible signal will sound. This situation may be ignored only for a short duration. NEVER operate the steering in relief for a prolonged period.

●Turning the steering wheel while the tractor is not running can promote damage on the tires and rims. Avoid such an action whenever possible.

7. About the 12V DC Outlet

This can be used when the key switch is in "ON" position. It can be used as a power source for electrical goods.

IMPORTANT: Avoid damage.

●Do not connect a light or load of more than 120 watts.

●Do not use as a cigarette lighter.

●Do not use when wet.

●Long-term usage of the 12V DC outlet with the

engine stopped causes the battery to run out.

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.

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.

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.

ALWAYS allow the tractor to fully cool down before accessing the engine, muffler, radiator or other hot components.

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.

■ 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

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 that space.

NEVER inhale the emission gas.

■ 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.

●Refuel outdoors or in a well-ventilated area.

●Wipe away spilled fuel immediately.

●To prevent static electric discharge, use a clean

approved non-metal fuel container.

●To prevent static electric discharge, use a clean approved plastic funnel that has no metallic screen mesh or filter.

IMPORTANT: Be careful to avoid damage.

●Dirt and water in the fuel can damage the engine.

●Remove dirt and debris from the fuel tank opening.

●Use clean, fresh, stabilized fuel.

●At the end of operation for the day, fill the fuel tank

to prevent condensation from occurring in the fuel tank.
