GENERAL OPERATION

1. Read, understand, and follow all instructions in 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

mowing. 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

travelling 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 and operational.

10. Slow down before turning.

11. Never leave a running unit unattended. Always disengage the blades (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 power

equipment-related injuries. These operators should evaluate their ability to operate the equipment 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 position).

25. When the machine is parked, stored, or left unattended, 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 (if equipped), disengage

the blades (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

can cause hearing loss though extended periods of exposure.

TRANSPORTING AND STORAGE

1. When transporting the unit on an open trailer, make sure it is facing 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 practices when refueling the unit after transportation

or storage.

3. 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.

4. 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 walk-behind or 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 conditions, incorrect hitching and load

distribution.

1. Mow up and down the face of 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 loose traction.

5. Avoid starting, stopping, or turning on a slope. If tires lose traction (i,e. machine stops forward motion on a

slope), disengage the blade(s) (PTO) and drive slow off the slope,

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

which could cause the machine to rollover.

7. Use extra care while operating machines with grass catchers or other attachments; they can affect the

stability of the unit. Do not use on steeps slopes.

8. Do not try to stabilize the machine by putting your foot on the ground (ride-on units).

9. Do not mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if

a wheel is over the edge of a cliff or ditch, or if an edge caves in.

10. Do not use grass catchers on steep slopes.

11. Do not mow slopes if you cannot back up them.

12.See your authorized dealer/retailer for recommendations of wheel weights or

counterweights to improve stability.

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

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

15. Do not turn on slopes unless necessary, and then, turn slowly and gradually uphill, if possible. Never

mow down slopes.

TOWED EQUIPMENT (RIDE-ON UNITS)

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. See attaching a trailer under OPERATION.

3. Never allow children or others in or on towed equipment,

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.

Select slow ground speed before driving onto slope.

Use extra caution when operating on slopes with rear- mounted grass catchers.

Mow up and down the face of slopes, not across. Use caution when changing directions and DO NOT

START OR STOP ON A 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.

CONTROL FUNCTIONS

The information below briefly describes the

function of individual controls. Starting,

stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks please read the entire section.

Ground Speed Levers /

Parking Brake

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

wheel and the right lever controls the right rear drive wheel and parking brake.

Pushing the levers out to the side, away from the operator's lap, locks the parking brake in PARK position

(inset, Figure 1). This is the proper position for starting the rider. Pulling the levers in across the operator's lap

puts the levers 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

further a lever is pushed, the faster the drive wheel will

turn.

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 gasoline/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 moisture 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 always use fuel stabilizer, especially before storage of 30 days or longer. Use fresh

fuel next season. See STORAGE instructions for

additional information, Never use engine or carburetor cleaner products in the

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 2 inches (5 cm) of

room in the tank for fuel expansion.

3, Install and hand tighten the fuel cap,

WARNING

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. 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.

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 four-

wheeled vehicles, The drive wheels are also your

steering 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

responsive, 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.

Avoid turf damage! To avoid turf damage, keep both

drive wheels moving while executing turns. Pivoting on one wheel, or dragging a wheel through a turn will damage your lawn.

Locate a smooth, flat 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.

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

WARNING

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

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

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.

Forward Travel

Figure 5. Forward Travel Figure 6. Reverse Travel

Reve rse Trave I

Practice Turning Around a Corner

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

mowing.

NOTE: Toprevent damaging your lawn by pivoting 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

simultaneously. Repeat several times.

Executing Turns Turning In Place

Figure 7. RightTurn Figure 8. 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 a Y-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. Be sure to keep both wheels turning to avoid turf damage.

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 experienced

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 better your control of the rider will be!

Mower Drive Belt Replacement

1. Park the rider on a level surface. Disengage the PTO, turn off the engine and set the ground speed control

levers to PARK. Remove the key.

2. Use the idler pulley arm (C, Figure 40) to release belt tension and remove the mower drive belt (A) from the

PTO pulley (E).

3. Remove the belt from the remaining deck pulleys.

Note: It is not necessary to remove the mower deck.

4. Install the new belt (A) as shown in Figure 40.

STORAGE

Before Storage

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:

• Turn the mower blades OFF, set the ground speed control levers to START / PARK, & remove the key from the ignition switch.

• 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

separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in

storage. To avoid engine problems use fuel stabilizer, especially

before storage of 30 days or longer.

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.

After Storage

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 operating.

NOTE: Specifications are correct at time of printing and are subject to change without notice.

The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers)

code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM, horsepower values are derived at 3600

RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to- engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating

conditions (temperature, humidity, altitude), and engine-to-engine variability, Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
