1-2

Sc2450 Operator's Manual

1. SAFETY PRECAUTIONS

2. 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 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, 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 “Chapter 13. MAINTENANCE”)

Sc2450 Operator's Manual

1-3

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 only front or rear mounted implements, install an appropriate weight(s) or counter balance 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.

3. 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.

9. Do not attach or use towed equipment by a drawbar or a drawing device/attachment. Usage of the drawbar or drawing device/attachment is/ are not allowed in this tractor.

Sc2450 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.

Sc2450 Operator's Manual

1. SAFETY PRECAUTIONS

4. Operate 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 4-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.

1. SAFETY PRECAUTIONS

1. Disengagement of the 4-wheel drive is recommended.

2. Remember that the braking characteristics differ between the 2-wheel drive and 4-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.

1. SAFETY PRECAUTIONS

7. Operate 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.

8. Use the 3-Point Hitch (Option)

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.

9. 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 re-weld 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

10. 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 “Chapter 15. SERVICE THE ELECTRICAL SYSTEM”.

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 “Check the Cooling System” on page 14-12 in “Chapter 14. PERIODIC SERVICE”).

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.

Sc2450 Operator's Manual

15.Keep the tractor securely supported while changing the wheels. Be sure to tighten the wheel bolts at the specified tightening torque.

1-9

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.
