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 disen- gage 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 operators posi- tion).

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

mechanical lock is used.

TP 600-4103-01 -ZT-UV

4. Always follow the engine manual instructions for storage preparations before storing the unit 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 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 distri-

bution.

1. Mow across slopes, not up and down.

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. Never mow down slopes.

6. 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.

7. Keep all movement on slopes slow andgradual. 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 attachments; they can affect the

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

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

10. Do not mow near drop-offs, ditches, or embank- ments. The mower could suddenly turn over if a

wheel !s 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 ifyou cannot back up them.

13. See your authorized dealer/retailer for recommenda- tions 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 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 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.

Select slow ground speed before driving onto slope.

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

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

START OR STOP ON SLOPE.

CHILDREN

Tragic accidents can occur ifthe 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, away from the operator's lap locks the parking brake in PARK position (inset, Figure

1). 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 fur- ther a lever is pushed, the faster the drive wheel will turn.

See 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 to close the choke. Move the lever back 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.

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 the mower deck. To turn the mower on, pull the

switch UP. Push the switch DOWN to turn the mower off. Note that the operator 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.

Fuel Tank

To remove the cap, turn counterclockwise.

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.

,AWARNING

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.

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

fuel next season. See STORAGE instructions for addi- tional 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 room in the tank for fuel expansion.

3. Install and hand tighten the fuel cap.

position and turn the ignition key to OFF. Remove the key. 5.

STARTING THE ENGINE

1. While sitting in the operator's seat, make sure the PTO switch is OFF and the ground speed control levers are locked in PARK positions.

2. Move the engine throttle control fully forward to FAST. Set the choke control to CLOSED.

NOTE: A warm engine may not require choking. In this case, set the choke control to OPEN.

3. Insert the key into the ignitionswitch and turn it to START.

4. After the engine starts, gradually move the choke

control back to OPEN position. Warm the engine by

running it for at least a minute before turning on the PTO switch, or driving the unit.

5. After warming the engine, ALWAYS operate the unit with the throttle set to FAST, especially when mowing.

Turn the PTO switch OFF, set the ground speed con- trol levers to PARK, turn the ignition switch OFF,

remove the key, and wait for all moving parts to stop. Locate the transmission release levers (C, Figure 3)

at the rear of the unit.

Pull both levers back and down to release the trans- missions (position B, Figure 3).

Set the ground speed control levers to DRIVE posi-

tions (levers moved in). The rider can now be pushed by hand.

After moving the rider, set the ground speed control

levers to PARK and push both transmission release levers forward to re-engage the transmissions (posi-

tion A, Figure 3).

DO NOTTOW RIDER

Towing the unit will cause transmission dam- age. Do not use another vehicle to push or

pull this unit.

MOWING

1. Make sure the PTO switch is OFF, the ground speed

control levers are locked intheir PARK positions, and the operator is in the seat.

2. Set the mower cutting height to the desired setting.

3. Start the engine (see STARTING THE ENGINE).

4. Set the throttle to FAST.

5. Turn the PTO switch ON to engage the mower deck.

6. Move the ground speed control levers from PARK positions to drive positions (levers in across the oper-

ator's lap).

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.

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 damaging your lawn by pivoting direct- ly 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!

CHECK / ADJUST PTO CLUTCH

• ILWARNING

To avoid serious injury, perform adjustments only with engine stopped, key removed and tractor on

level ground.

Service interval: 200 Hours. The PTO clutch is engaged and disengaged by the PTO

switch. The clutch powers and brakes the mower blades. Check the PTO clutch adjustment every 200 hours of operation. Also perform the following procedure if the clutch is slipping, will not engage, or if a new clutch has

been installed.

1. Remove key from ignition switch and disconnect spark plug wires to prevent the possibility of acciden- tal starting while the PTO is being adjusted.

2. See Figure 22. Note the position of the 3 adjustment windows (A) in the side of the brake plate and the nylock adjustment nuts (B).

3. Insert a .012"-.015" (2,5-4mm) feeler gauge (C) through each window, positioning the gauge between

the rotor face and the armature face as shown in

Figure 23.

4. Alternately tighten the adjustment nuts (B, Figure 22) until the rotor face and armature face just contacts

the gauge.

5. Check the windows for an equal amount of tension when the gauge is inserted and removed, and make

any necessary adjustments by tightening or loosen- ing the adjustment nuts.

NOTE: The actual air gap between the rotor and arma-

ture may vary even after performing the adjustment pro- cedure. This is due to dimensional variations on compo- nent parts, and is an acceptable condition.

6. Check the mower blade stopping time. The mower blades and mower drive belt should come to a com-

plete stop within five seconds after the electric PTO switch is turned off. If adjustment does not stop a

mower braking problem, replace the electric PTO clutch.

Side to Side Leveling

If the cut is uneven, the mower may need leveling. Unequal or improper tire pressure may also cause an

uneven cut. See CHECK TiRE PRESSURE.

1. With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn

the front wheels straight forward. Turn the engine off, set the ground speed control levers to PARK, and wait for all moving parts to stop.

2. Check for bent blades and replace if necessary.

3. Check the tire pressures. See CHECK TiRE PRES- SURE.

4. Set the cutting height to mid position. Arrange the mower blades so that they are pointing from side-to- side (Figure 38).

5. Measure the distance between the tips of the outside blades and the ground (Figures 37 & 38). If there is more than 1/8" (3mm) difference between the meas- urements on each side, proceed to step 6. If the dif- ference is 1/8" (3mm) or less, proceed to Front To

Back Leveling.

6. See Figure 39. Loosen the outside nut (A) and taptite screw (C), then turn the eccentric nut (B) to raise or

lower the left side of the deck. When the mower deck is level, hold the eccentric nut while tightening the

outside nut. Tighten the taptite screw (C).
