GENERAL OPERATION

t. Read, understand, and follow all instructionsin the

manual and on the unit before starting.

2. Do not put hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.

3. Only allow responsible adults, who are familiar with the instructions, to operate the unit (local regulations

can restrict operator age).

4. Clear the area of objects such as rocks, toys, wire,

etc., which could be picked up and thrown by the blade(s).

5. Be sure the area is clear of other people before mow-

ing. Stop the unit if anyone enters the area.

6. Never carry passengers.

7. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while travel-

ling in reverse.

8. Never direct discharge material toward anyone. Avoid discharging material against a wall or obstruction.

Material may ricochet back toward the operator. Stop

the blade(s) when crossing gravel surfaces.

9. Do not operate the machine without the entire grass catcher, discharge guard (deflector), or other safety

devices in place.

10. Slow down before turning.

11. Never leave a running unit unattended. Always disen- gage the PTO, set parking brake, stop engine, and

remove keys before dismounting.

12. Disengage blades (PTO) when not mowing. Shut off

engine and wait for all parts to come to a complete stop before cleaning the machine, removing the grass

catcher, or unclogging the discharge guard.

13. Operate the machine only in daylight or good artificial

light.

14. Do not operate the unit while under the influence of alcohol or drugs.

15 Watch for traffic when operating near or crossing

roadways.

16. Use extra care when loading or unloading the unit into a trailer or truck.

17. Always wear eye protection when operating this unit.

18. Data indicates that operators, age 60 years and above, are involved in a large percentage of riding

mower-related injuries. These operators should eval- uate their ability to operate the riding mower safely

enough to protect themselves and others from injury.

19. Follow the manufacturer's recommendations for wheel weights or counterweights.

20. Keep in mind the operator is responsible for accidents occurring to other people or property.

21. All drivers should seek and obtain professional and practical instruction.

22. Always wear substantial footwear and trousers.

Never operate when barefoot or wearing sandals.

23. Before using, always visually check that the blades and blade hardware are present, intact, and secure.

Replace worn or damaged parts.

24. Disengage attachments before: refueling, removing an attachment, making adjustments (unless the

adjustment can be made from the operator's posi- tion).

25. When the machine is parked, stored, or left unattend- ed, lower the cutting means unless a positive mechanical lock is used.

26. Before leaving the operator's position for any reason, engage the parking brake, disengage the PTO, stop

the engine, and remove the key.

27. To reduce fire hazard, keep the unit free of grass, leaves, & excess oil. Do not stop or park over dry

leaves, grass, or combustible materials.

28. It is a violation of California Public Resource Code Section 4442 to use or operate the engine on or near

any forest-covered, brush-covered, or grass-covered land unless the exhaust system is equipped with a

spark arrester meeting any applicable local or state laws. Other states or federal areas may have similar

laws.

TRANSPORTING AND STORAGE

t. When transporting the unit on an open trailer, make

sure it isfacing forward, in the direction of travel. If

the unit is facing backwards, wind lift could damage the unit.

2. Always observe safe refueling and fuel handling prac- tices when refueling the tractor after transportation or

storage.

3. Never store the unit (with fuel) in an enclosed poorly ventilated structure. Fuel vapors can travel to an igni- tion source (such as a furnace, water heater, etc.) and cause an explosion. Fuel vapor is also toxic to

humans and animals.

TP 600-2459-06-UV-SIvIA

4. Always follow the operator's manual instructions for storage preparations before storing the tractor for both short and long term periods.

5. Always follow the engine manual instructions for proper start-up procedures when returning the unit to

service.

6. Never store the unit or fuel container inside where

there is an open flame or pilot light, such as in a water heater. Allow unit to cool before storing.

SLOPE OPERATION

Slopes are a major factor related to loss-of-control and tip- over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution, if you cannot back up the slope or if you feel uneasy on it, do not operate

on it. Control of a ride-on machine sliding on a slope will not be

regained by the application of the brake. The main reasons for loss of control are: insufficient tire grip on the ground, speed too fast, inadequate braking, the type of machine is unsuitable for its task, lack of awareness of the ground con- ditions, incorrect hitching and load distribution.

1. Mow up and down slopes, not across.

2. Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles.

3. Choose a slow speed so that you will not have to stop or change speeds while on the slope.

4. Do not mow on wet grass. Tires may lose traction.

5. Always keep unit in gear especially when traveling down slopes. Do not shift to neutral and coast down-

hill.

6. Avoid starting, stopping, or turning on a slope. If tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.

7. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction,

which could cause the machine to rollover.

8. Use extra care while operating machines with grass catchers or other attachment; they can affect the sta- bility of the unit.

9. Do not try to stabilize the machine by putting your foot on the ground.

10. Do not mow near drop-offs, ditches, or embank- ments. The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge

caves in.

11. Do not use grass catchers on steep slopes.

12. Do not mow slopes you cannot back up.

13. See your authorized retailer for recommendations of wheel weights or counterweights to improve stability.

14. Remove obstacles such as rocks, tree limbs, etc.

15. Use slow speed. Tires may lose traction on slopes even through the brakes are functioning properly.

16. Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

TOWED EQUIPMENT

1. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.

2. Follow the manufacturer's recommendations for weight limit for towed equipment and towing on

slopes.

3. Never allow children or others in or on towed equip- ment.

4. On slopes, the weight of the towed equipment may cause loss of traction and loss of control.

5. Travel slowly and allow extra distance to stop.

6. Do not shift to neutral and coast down hill.

WARNING

Never operate on slopes greater than 17.6 percent (10 °) which is a rise of 3-1/2 feet (106 cm) vertically in 20 feet (607 cm) horizontally.

When operating on slopes use additional wheel weights or counterweights. See your retailer to determine which weights are available and appropriate for your unit.

Select slow ground speed before driving onto slope.

In addition to front and rear weights, use extra caution when operating on slopes with rear-mounted grass

catcher.

Mow UP and DOWN the slope, never across the face, use caution when changing directions and DO NOT

START OR STOP ON SLOPE.

CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the unit and the mowing activity. Never assume that children will remain where you last saw them.

1. Keep children out of the mowing area and under the watchful care of another responsible adult.

2. Be alert and turn unit off if children enter the area.

3. Before and during reverse operation, look behind and down for small children.

4. Never carry children, even with the blade(s) off. They may fall off and be seriously injured or interfere with

safe unit operation. Children who have been given

rides in the past may suddenly appear in the mowing

area for another ride and be run over or backed over by the machine.

5. Never allow children to operate the unit.

6. Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure

vision.

EMISSIONS

1. Engine exhaust from this product contains chemicals known, in certain quantities, to cause cancer, birth defects, or other reproductive harm.

2. Look for the relevant Emissions Durability Period and Air Index information on the engine emissions label.

IGNITION SYSTEM

1. This spark ignition system complies with Canadian ICES-O02.

SERVICE AND MAINTENANCE

Safe Handling of Gasoline

1. Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

2. Use only approved gasoline containers.

3. Never remove the gas cap or add fuel with the engine running. Allow the engine to cool before refueling.

4. Never fuel the machine indoors.

5. Never store the machine or fuel container where there is an open flame, spark, or pilot light such as near a

water heater or other appliance.

6. Never fill containers inside a vehicle or on a truck bed

with a plastic bed liner. Always place containers on the ground away from your vehicle before filling.

7. Remove gas-powered equipment from the truck or

trailer and refuel it on the ground, if this is not possi-

ble, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dis-

penser nozzle.

8. Keep nozzle in contact with the rim of the fuel tank or

container opening at all times until fueling is com-

plete. Do not use a nozzle lock-open device.

9. if fuel is spilled on clothing, change clothing immedi-

ately.

10. Never over fill the fuel tank. Replace gas cap and tighten securely.

11. Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

12. If fuel is spilled, do not attempt to start the engine but

move the machine away from the area of spillage and

avoid creating any source of ignition until fuel vapors

have dissipated.

13. Replace all fuel tank caps and fuel container caps

securely.

Service & Maintenance

1. Maintain or replace safety and instruction labels as necessary.

2. Never run the unit in an enclosed area where carbon monoxide fumes may collect.

3. Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.

4. Never tamper with safety devices. Check their proper

operation regularly and make necessary repairs if they are not functioning properly.

5. Keep unit free of grass, leaves, or other debris build- up. Clean up oil or fuel spillage.

6. Stop and inspect the equipment if you strike an

object. Repair, if necessary, before restarting.

7. Never make adjustments or repairs with the engine running unless specified otherwise in the owner's

manual.

8. Do not remove the fuel filter when the engine is hot

as spilled gasoline may ignite. Do not spread fuel line clamps further than necessary. Ensure clamps grip

hoses firmly over the filter after installation.

9. Do not use gasoline containing METHANOL, gasohol

containing more than 10% ETHANOL, gasoline addi- tives, or white gas because engine/fuel system dam- age could result.

10. If the fuel tank must be drained, it should be drained outdoors.

11. Replace faulty silencers/mufflers.

12. Grass catcher components are subject to wear, dam- age, and deterioration, which could expose moving

parts or allow objects to be thrown. Frequently check components and replace with manufacturer's recom-

mended parts, when necessary.

13. Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when

servicing them.

14. Check brake operation frequently. Adjust and service as required.

15. Use only factory authorized replacement parts when making repairs.

16. Always comply with factory specifications on all set- tings and adjustments.

17. Only authorized service locations should be utilized for major service and repair requirements.

18. Never attempt to make major repairs on this unit unless you have been properly trained, improper

service procedures can result in hazardous operation, equipment damage and voiding of manufacturer's warranty.

19. On multiple blade mowers, take care as rotating one blade can cause other blades to rotate.

20. Do not change engine governor settings or over- speed the engine. Operating the engine at excessive

speed can increase the hazard of personal injury.

21. Disengage drive attachments, stop the engine,

remove the key, and disconnect the spark plug wire(s)

before: clearing attachment blockages and chutes, performing service work, striking an object, or if the

unit vibrates abnormally. After striking an object, inspect the machine for damage and make repairs

before restarting and operating the equipment.

22. Never place hands near the moving parts, such as a hydro pump cooling fan, when the tractor is running.

(Hydro pump cooling fans are typically located on top of the transaxle).

23. Units with hydraulic pumps, hoses, or motors: WARN-

iNG: Hydraulic fluid escaping under pressure may

have sufficient force to penetrate skin and cause seri- ous injury. Ifforeign fluid is injected into the skin it

must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene

may result. Keep body and hands away from from pin holes or nozzles that eject hydraulic fluid under high

pressure. Use paper or cardboard, and not hands, to search for leaks. Make sure all hydraulic fluid con-

nections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. If leaks occur, have the unit serviced imme-

diately by an authorized service center.

24. WARNING: Stored energy device, improper release of springs can result in serious personal injury.

Springs should only be removed by an authorized service center.

25. Models equipped with an engine radiator: WARNING: Stored energy device. To prevent serious bodily injury

Figure 1. Controls

The information below briefly describes the function of individualcontrols. Starting, stopping, driving, and mowing require the combined use of several controls applied inspecific sequences. To learn what combination and sequence of controls to use for various tasks please read the entire section.

Ground Speed Levers

These levers control the ground speed of the rider. The left lever controls the left rear drive wheel and the right lever controls the right rear drive wheel.

Pushing the levers out, away from the operator's lap locks them in PARK positions (inset, Figure 1). Pulling the levers in across the operator's lap puts them in DRIVE positions.

From DRIVE position, moving a lever forward increases the FORWARD speed of the associated wheel. Pulling back on a lever increases the REVERSE speed. The fur- ther a lever is pushed, the faster the drive wheel will turn.

See the DRiViNG PRACTICE for steering instructions.

_ Throttle Control

The throttle controls engine speed. Always operate at FULL throttle when mowing. Move the lever forward to the detent for FULL throttle (FAST). Move the throttle back to decrease engine speed to IDLE (SLOW).

Choke

Close the choke for cold starting. Open the choke once the engine starts. A warm engine may not require chok- ing. Move the lever forward past the FULL throttle detent

to close the choke. Move the lever back to the detent to open the choke.

Mower Height of Cut Adjustment

To adjust cutting height, rotate the turn crank clockwise to raise the mower deck and counterclockwise to lower

the mower deck.

ignition Switch

The ignition switch starts and stops the engine; it has three positions:

OFF Stops the engine and shuts off the

electrical system.

RUN Allows the engine to run and powers the

electrical system.

START Cranks the engine for starting.

NOTE." Never leave the ignition switch in the RUN posi-

tion with the engine stopped. This drains the battery.

B Hour Meter

The hour meter measures the number of hours the key has been in the RUN position. The hour meter will flash an oil change indicator at 5 hours, and a lubrication reminder every 50 hours. These reminders will automati- cally reset themselves.

NOTE." The hour meter will register the passage of time

when the key is in the RUN position, even if the engine is

not running.

PTO Switch

The PTO (Power Take-Off) switch engages and disen- gages an electric clutch attached to the engine crank- shaft. This electric clutch drives and stops the mower deck. To turn the mower on, pull the switch UP. Push the switch DOWN to turn the mower off. Note that the opera- tor must be seated firmly in the rider seat for the PTO to

function.

Transmission Release Levers

The transmission release levers deactivate the transmis- sions so that the unit can be pushed by hand. See

PUSHING THE UNIT BY HAND for operational informa- tion.

Seat Adjustment Knob

The seat can be adjusted forward and backward. Tip the seat forward, loosen the adjustment knob, slide the seat to the desired position, and tighten the knob.

Fuel Tank

To remove the cap, turn counterclockwise.

Parking Brake

DRIVE Releases the parking brake. PARK Locks the parking brake.

GENERAL OPERATING SAFETY

Before first time operation:

• Be sure to read all information in the Safety and Operation sections before attempting to operate this

rider and mower.

• Become familiar with all of the controls and how to stop

the unit.

• Drive in an open area without mowing to become accus-

tomed to driving the unit.

Pull the parking brake lever up to engage the parking brake (PARK position). Move the lever fully down to dis- engage the parking brake (DRIVE position).

NOTE: Tostart the unit the parking brake must be in PARK position.

,WARNING

If you do not understand how a specific control functions, or have not yet thoroughly read the

CONTROL FUNCTIONS section, do so now.

Do NOT attempt to operate the rider without first

becoming familiar with the location and function of ALL controls.

CHECKS BEFORE STARTING

• Check that the crankcase oil is filled to full mark on dipstick.

• Adjust the seat position and make certain you can

reach all controls. Fill the fuel tank with fresh fuel.

FUEL RECOMMENDATIONS

For daily operation: Use only unleaded gasoline with a pump sticker octane rating of 87 or higher. Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is approved as a fuel. Methyl Teriary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE by volume) are approved as a fuel. No other gaso- line/alcohol or gasoline/ether blends are approved. Do

not use fuel additives other than fuel stabilizer. For storage: CAUTION: Alcohol blended fuels (called

gasohol or using ethanol or methanol) can attract mois- ture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine, and let it run until the fuel lines and carburetor are empty (see STORAGE for fuel draining procedure). Use fresh fuel next season. See

STORAGE instructionsfor additional information. Never use engine or carburetor cleaner products inthe

fuel tank or permanent damage may occur. To add fuel:

1. Remove the fuel cap (B, Figure 2).

2. Fill the tank. Do not overfill. Leave room in the tank for fuel expansion.

3. Install and hand tighten the fuel cap.

tLWARNING

Never allow passengers to ride on the unit. Before leaving the operator's position for any

reason, engage the parking brake, disengage the PTO, stop the engine and remove the key.

To reduce fire hazard, keep the engine, rider and mower free of grass, leaves and excess grease.

Do not stop or park rider over dry leaves, grass or combustible materials.

DRiViNG PRACTICE-

BASIC DRIVING

WARNING: Never operate on slopes greater than 17.6% (10°). See SLOPE OPERATION in the safety section. Zero turn riders operate differently from other bur- wheeled vehicles. The drive wheels are also your steer- ing wheels. If you cannot drive the unit on a hill, you will not be able to steer the unit on it. Operating zero turn units on slopes requires extra caution.

The lever controls of the zero turn rider are very respon- sive, and learning to gain a smooth and efficient control of the rider's forward, reverse, and turning movements will take some practice.

Spend some time going through the following maneuvers and becoming familiar with how the unit accelerates,

travels, and steers -- before you begin mowing --is absolutely essential to getting the most out of the zero turn rider.

Locate a smooth, fiat area of your lawn -- one with plenty of room to maneuver. (Clear the area of objects, people and animals before you begin.) Operate the unit at mid-throttle during this practice session (ALWAYS operate at full throttle when mowing), and turn slowly to prevent tire slippage and damage to your lawn.

Smooth Travel

The lever controls of the zero turn rider are

highly responsive. The BEST method of

handling the ground speed control levers is in three steps -- as shown in Figure 4.

FIRST place your hands onto the levers as

shown. SECOND, to go forward

gradually push the levers forward with your palms.

THIRD, to speed up move the levers farther

forward. To slow down smoothly, slowly move

the levers back toward neutral.

Figure 4. Move Control Levers Gradually

We suggest you begin with the Smooth Travel procedure to the right, and then advance through the forward, reverse, and turning maneuvers.

You must set the parking brake to DRIVE prior to moving the control levers out of park position.

WARNING

Do not mow in reverse unless absolutely necessary. Always look down and behind before and while travelling in reverse.

Forward Travel

Forward Travel Practice

Gradually move both ground speed control levers evenly FORWARD from neutral. Slow down and repeat.

Reverse Travel Practice LOOK DOWN & BEHIND, then gradually move both

ground speed control levers evenly BACK from neutral. Slow down and repeat.

NOTE: Practice backing up for several minutes before attempting to do so near objects. The rider turns as

sharply in reverse as when going forward, and backing

up straight takes practice.

Reverse Travel

Figure 5. Forward Travel Figure 6. Reverse Travel

Practice Turning Around a Corner

While traveling forward allow one handle to gradually return back toward neutral. Practice several times before

mowing.

NOTE." Toprevent piveting directly on the tire tread, it is best to keep both wheels going at least slightly forward.

Practice Turning in Place

To "zero turn" means to turn in place. To turn in place, gradually move one ground speed control lever forward

from neutral and one lever back from neutral simultane- ously. Repeat several times.

Executing Turns

Figure 7. RightTurn Figure 8. Turning in Place

Turning In Place

ADVANCED DRIVING

Executing an End=Of=Row Zero Turn

Your zero turn rider's unique ability to turn in place allows you to turn around at the end of a cutting row rather than having to stop and make aY-turn before starting a new row.

For example, to execute a right end-of row zero turn:

1. Slow down at the end of the row.

2. Move the LEFT ground speed control lever forward slightly while moving the RIGHT ground speed control lever back to

center and then slightly back from center.

3. Begin mowing forward again.

This technique turns the rider RIGHT and slightly overlaps the row just cut --eliminating the need to back up and re-cut missed grass.

As you become more familiar and experi- enced with operating the zero turn rider, you

will learn more maneuvers that will make your

mowing time easier and more enjoyable.

Remember, the more you practice, the bet= ter your control of the rider will be!

Figure 31. Cutting Height Adjustment

A. Cutting Height Adjustment Crank

WARNING

Keep open flames and sparks away from the battery; the gasses coming from it are highly explosive. Ventilate the battery well during charging.

A dead battery or one too weak to start the engine may be the result of a defect in the charging system or other electrical component. If there is any doubt about the cause of the problem, contact a Sears Parts & Repair Center. If you need to replace the battery, follow the steps under Cleaning the Battery & Cables in the Regular Maintenance Section.

To charge the battery, follow the instructions provided by the battery charger manufacturer as well as all warnings included in the safety rules sections of this book. Charge the battery until fully charged (until the specific gravity of the electrolyte is 1.250 or higher and the electrolyte tem- perature is at least 60° F). Do not charge at a rate higher than 10 amps.

ENGINE ADJUSTMENTS

The carburetor is designed to deliver the correct fuel-to- air mixture to the engine under all operating conditions.

The main fuel jet is calibrated at the factory and is not adjustable. The low idle fuel adjusting needle is also set

at the factory and normally does not need adjustment.

Figure 32. Brake Adjustment A. Brake Rod

B. Adjustment Nut C. Brake Lever

To ensure proper operation at altitudes above 5000 feet, it may be necessary to have an authorized Kohler dealer install a special high-altitude jet kit in the carburetor. If a high-altitude kit as been installed, the engine must be converted back to the original jet size before it is operat- ed at lower altitudes. If not, overheating and engine damage can result.

Before you store your unit for the off-season, read the Maintenance and Storage instructions in the Safety Rules section, then perform the following steps:

• Disengage the PTO, set the parking brake, & remove the key.

Check all fluid levels. Check all maintenance items.

• Battery life will be increased if it is removed, put in a cool, dry place and fully charged about once a month. If the battery is left in the unit, disconnect the negative cable.

It is important to prevent gum deposits from forming in the essential fuel system parts such as the carburetor, fuel filter, fuel line, and fuel tank during storage. Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to the sepa- ration and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in stor- age.

To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Follow these instructions;

1. Stop the engine, remove the key, and allow the engine to cool.

2. Place a suitable container below the fuel filter (A, Figure 39") to catch spilled fuel, and place a contain-

er suitable to hold the contents of the fuel tank next to the unit.

3. Using locking pliers, clamp the fuel line between the

fuel filter (A) and fuel tank.

4. Spread the clamp on the fuel filter only far enough to

slide the clamp away from the filter.

5. Disconnect the fuel line from the fuel filter.

6. Route the fuel line into a suitable container, remove

the locking pliers, and drain the fuel tank.

7. Reconnect the fuel filter, and secure with the clamp.

8. Start and run the unit until all fuel is consumed.

WARNING

Never store the unit (with fuel) in an enclosed, poorly ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion.

Fuel vapor is also toxic to humans and animals.

WARNING

Gasoline is highly flammable and must be handled with care. Never fill the tank when the

engine is still hot from recent operation. Do not allow open flame, smoking or matches in the area. Avoid over-filling and wipe up any spills.

Before starting the unit after it has been stored:

Check all fluid levels. Check all maintenance items.

• Fill with FRESH fuel.

• After starting, allow the engine to warm before oper- ating.
